Why Do Onions Make Us Cry?

Onions are one of the most common staple foods around the globe. Ironically, for a vegetable so delicious, they can often be tear-jerkers.

Read on to learn why onions cause your eyes to tear and sting, and what you can do to minimize discomfort.

Why Does Cutting Onions Cause Tearing?

Onions produce a sulfur compound called propyl sulfoxide that is stored in the cells of the onion bulb (the part of the onion we eat). Onions grow underground, where they can be eaten by all types of creatures. This odorous sulfuric compound acts as a deterrent to small animals with big appetites.

When one slices into an onion and breaks open its cells, the sulfur compound is released and mixes with the moisture in the air — turning it into smelly and irritating sulfuric acid. When this chemical rises up and comes in contact with your eyes, it stings!

To keep your eyes from potentially being damaged from this chemical exposure, your brain triggers your eyes to tear and flush out the irritating gas particles. Once enough tears have flushed out the sulfuric acids particles from the eye, clear vision and comfort is usually restored. Although your eyes may sting and feel unpleasant, symptoms are temporary and the sulfuric acid won’t damage your eyes.

How Can I Reduce Eye Discomfort When Chopping Onions?

Most experienced chefs will tell you that chilling your onions in the fridge for at least 30 minutes before slicing them will reduce the amount of tearing they cause. Propyl sulfoxide escapes slower in cooler temperatures, reducing the amount of sulfuric acid in the air.

You can also try cutting the onions at arm’s length, or direct the odorous air away with a small fan. Some say that chopping onions immersed in water also helps. Another option is to wear kitchen goggles to protect your eyes.

Furthermore, try to use fresh onions whenever possible. The longer an onion has been stored, the more likely it will induce tearing and discomfort. Try to avoid slicing near the root end of the bulb, as that area has the highest concentration of sulfuric compounds.

Still Having Eye Problems Out of the Kitchen?

If you frequently suffer from eye irritation — and not just while cutting onions — we can help. At Lakeline Vision Source, we treat a wide range of eye conditions and can provide you with the treatment and relief you seek.

Why Are Eye Exams Important?

To ensure healthy vision, children and adults should visit their eye doctor every year for a routine comprehensive eye exam to determine whether their vision has changed, and to check for eye diseases and other health problems.

What Can Eye Exams Detect?

In addition to assessing your vision, a comprehensive eye exam can diagnose eye disease. Eye diseases can go undetected for years because their symptoms may not become apparent until the condition is at a more advanced stage. Glaucoma, diabetic retinopathy, and macular degeneration are prime examples. Unfortunately, by then it may be too late to prevent irreversible vision loss and even blindness.

For children, an eye exam can also help detect visual dysfunction, which can manifest as learning disabilities, developmental delay, or behavioral issues.

By undergoing annual comprehensive eye exams you are proactively taking measures to protect you and your child’s eye health. The earlier a visual problem is diagnosed, the better the outcome. Annual eye exams are all the more important if you have a family history of visual problems.

Older Adults Need More Frequent Monitoring

As you age, your vision changes in subtle and not-so-subtle ways. With age comes the risk of developing retinal detachment, diabetic retinopathy, glaucoma and macular degeneration. Age-related farsightedness — a natural part of the aging process — tends to develop when a person is in their 40s. For this reason older adults should visit their eye doctor more frequently for regular monitoring.

Eye Exams Can Reveal Your Overall Health

Your eyes are the windows to your overall health and reveal much more than eye problems. An eye doctor can often detect issues such as diabetes or high blood pressure by analyzing your eyes’ blood vessels. Your inflamed retina may signal a potential autoimmune disorder; blurry vision may indicate fluctuating blood sugar levels; and the bulging of the eyes may signal thyroid disease.

Protect your eye health and overall wellness by contacting Lakeline Vision Source today. We can help identify potential health problems early on, preventing irreversible damage.

Pink Eye? It Could Be Coronavirus

How to prevent conjunctivitis and protect your eyes

When you have a virus, especially one that causes a hacking cough, runny nose, and other symptoms of a common cold or flu, it’s typical for your eyes to also get puffy and red. You may be suffering from viral conjunctivitis, also known as pink eye.

How do viruses get into your eyes?

It’s rather simple. When you’re sick, you can easily transfer viruses to your eyes by sneezing, coughing into your hands, or blowing your nose – and then touching the area around your eye.

The coronavirus – pink eye connection

According to the American Academy of Ophthalmology (AAO), doctors have discovered that COVID-19 can cause conjunctivitis. If you’re standing within six feet of an infected person, and they cough or sneeze, the virus can enter your eye. Alternatively, if someone sneezes and virus particles land on the shopping cart that you take and push around a store, and then you touch your eyes without washing your hands first – you’re giving the virus direct access.

However, despite the apparent ease with which coronavirus can infect eyes, the AAO reports that only about 1 – 3% of all patients with the virus contract pink eye.

Preventing pink eye

Like always, prevention is the most effective medicine! Eye care professionals recommend following these tips to help prevent getting viral conjunctivitis:

  • Wash your hands correctly

The CDC instructs people to wash their hands in accordance with these steps: wet your hands, turn off the tap, apply soap, lather and scrub for 20 seconds, turn on tap and rinse. Air dry your hands, use a disposable paper towel and discard it immediately, or use a clean (not shared) towel.

  • Keep your fingers away from your face

No rubbing or wiping your eyes! Even if you don’t feel any symptoms of coronavirus, it’s essential not to touch any part of your face. To wipe away tears or remove makeup, use a clean tissue.

  • Don’t share your personal things

As generous as you may feel about letting others use your personal items, now’s the time to keep things to yourself. For example, the CDC recommends not sharing eye drops, makeup, makeup brushes, contact lenses cases, pillowcases, or towels. Pink eye is highly contagious.

  • Consider wearing glasses instead of contacts

While there’s currently no evidence to prove that wearing contacts raises your risks of contracting the novel coronavirus, there’s some evidence that shows you can get Covid-19 by touching a contaminated surface and then touching your eyes. In general, contact lenses wearers touch their eyes more often than people who wear eyeglasses, so it may be smart to make a temporary switch from contact lenses to glasses. However, this is only a friendly recommendation and not a hard-and-fast rule. If you prefer to stick with wearing contacts, washing your hands thoroughly can help keep you and your eyes safe.

Treatment for conjunctivitis

Regardless of whether your pink eye is caused by coronavirus or a different virus, there is no treatment for viral conjunctivitis. Usually, it goes away on its own within one to two weeks.

To alleviate your painful symptoms, eye doctors recommend:

  • Taking an over-the-counter pain medication, such as acetaminophen, ibuprofen or any anti-inflammatory drug
  • Applying a warm compress on your eye for a few minutes; take care to use a clean wash cloth each time and for each eye
  • Use artificial tears (lubricating eye drops) to soothe your eye irritation; don’t touch the bottle tip to your eye

Are you sick and have pink eye symptoms?

Now is not the time to make a DIY diagnosis. Eye redness, even if you have a virus, doesn’t necessarily indicate that you have conjunctivitis. A wide range of other conditions can lead to the same symptoms. Contact an eye doctor near you for help to figure out what’s causing your eye pain. Don’t visit your eye care practice without calling for guidance first, because extra precautions must be taken with patients who may have COVID-19.

Eye Pain – Causes and Treatment

What’s causing my burning eyes, and what should I do?

Eye pain is a very general term that people use to describe symptoms they feel in, on, around, or behind their eyes. The pain may be felt in just one eye or both eyes. Sometimes it’s entirely obvious what’s causing the problem – such as an injury or a torn contact lens. But other times, figuring out the root of the problem can be more challenging. Contact Lakeline Vision Source to book an urgenteye exam in Cedar Park, Texas – we’ll diagnose your problem and provide treatment to bring relief.

Pinpoint your pain

The eye doctor diagnoses the problem and provides treatment to soothe your eye pain; it helps if you can identify exactly what part of the eye hurts, for example:

  • Cornea: the clear outer surface of your eye
  • Sclera: the whites of your eyes
  • Conjunctiva: the thin membrane that coats your sclera and inner eyelid
  • Iris: colored section of your eye, with the pupil in the center
  • Orbit: eye socket; the bony depression where your eye and its muscles are located
  • Extraocular muscles: responsible for rotating your eye
  • Eyelids: external covering over your eyes that protect and spread lubrication

Common causes of eye pain

The following is a review of the most typical causes of eye pain that we treat in our Cedar Park, Texas , eye clinic:

  • Conjunctivitis: also known as pink eye, this is an eye infection that leads to swelling of the conjunctiva. Classic symptoms include bloodshot eyes, oozing discharge, itchiness, burning eyes, and the feeling that you need to keep rubbing your eyes. When it is a bacterial infection, your eye doctor will prescribe antibiotic eye drops or ointment as treatment.
  • Blepharitis: an infection or inflammation of the eyelid that is often irritating and is a common cause of dry eye symptoms
  • Corneal abrasions: these are the same as corneal scratches, which can be quite painful. Vigorous rubbing of your eyes can actually cause corneal abrasions, as well as any foreign object contacting your delicate eye surface. Generally, corneal scratches heal within a few days without complications.
  • Corneal infections (keratitis): a bacterial or viral infection can cause your cornea to become infected or inflamed. Improper hygiene of contact lenses is the usual cause of corneal infections.
  • Foreign bodies: when any object gets stuck in your eye, even a speck of dirt, it can irritate it. Flushing out the item will usually bring relief within a short period.
  • Dry eyes: this type of eye pain usually starts more gradually than a corneal scratch or foreign object and often causes stinging or burning eyes. Lubricating eye drops are often enough to restore comfort.
  • Migraine headaches: the pain is usually concentrated behind only one eye and it’s often accompanied by pain elsewhere on the same side of your head
  • Sinus infection: the symptoms are typically more mild than pain from a migraine
  • Stye: this is an inflamed spot on the edge of your eyelid, which generally goes away after a few days – especially if you apply warm compresses to your eyelid several times a day
  • Optic neuropathy: the pain caused by this condition is usually severe, and immediate medical attention is required. When left untreated, it can cause permanent vision loss. Usually, the eye pain is accompanied by reduced visual acuity and a dimming of your color vision. Moving your eyes will make the pain worse.

When to see an eye doctor for eye pain

Certain cases require emergency medical care, while other types of eye pain require a visit to your eye doctor – but they are not as urgent.

Emergency eye care is needed when:

  • Eye pain is accompanied by fever, headache, and unusual light sensitivity
  • You experience sudden vision changes
  • You also experience vomiting or nausea
  • The pain is triggered by a foreign object or chemical splashed in your eye
  • You suddenly see halos around lights
  • There is inflammation in or around your eyes
  • It’s difficult to move your eye or keep it open
  • Blood or pus is coming out from your eyes

Don’t take chances with your vision!

Even if you don’t have any of the above eye emergency symptoms, you should still regard any eye pain as a reason to visit your eye doctor. To keep your vision safe for as long as possible, schedule an eye exam with our eye doctor near you in Cedar Park, Texas , as soon as possible.

At Lakeline Vision Source, we put your family’s needs first. Talk to us about how we can help you maintain healthy vision. Call us today: 512-918-3937 or book an appointment online to see one of our Cedar Park eye doctors.

Blinking and Dry Eye: The Clear Connection

Are Your Eyes Causing Motion Sickness?

FOLLOW US:

Do I Have Symptoms of Dry Eye?

The symptoms of dry eye can range from mild to very painful. How do you know if you’re suffering from this common condition? And what can you do about it?

The best way to get a diagnosis of dry eye – or rule it out with certainty– is with an eye exam. Contact Lakeline Vision Source to book an eye exam in Cedar Park, Texas . Our optometrists know what to look for when inspecting for dryeye syndrome and develop a personalized treatment plan to comfort your sore eyes.

Common signs of dry eye

Typically, these symptoms affect both eyes and can be a good indicator that you are indeed suffering from dry eye syndrome:

  • Stinging or burning in your eyes
  • Itchy eyes
  • Stringy mucus inside or around your eyes
  • Light sensitivity
  • Eye redness
  • A sensation that something is stuck in your eyes
  • Wearing contact lenses is uncomfortable
  • Difficulty with nighttime driving
  • Watery eyes
  • Blurred vision
  • Eye fatigue

Link between watery eyes and dry eyes

Many people mistakenly think that because their eyes are watering excessively, they can’t possibly have dry eye syndrome. Not true! As our Cedar Park, Texas , eye doctor explains, dry eyes can lead to reflex tearing. This condition occurs because the insufficient moisture on your eye surface irritates your eye, and your body then floods the area with tears to compensate for the dryness. However, because these tears are composed mainly of water – without the lubricating lipids that are necessary for healthy tears – they evaporate rapidly and can’t properly disperse moisture over your eye’s surface.

Risk factors for dry eye

Along with the above symptoms, if you have any of the usual risk factors for dry eye – then the likelihood of experiencing this irritating vision condition is even higher. The most common risk factors include:

  • Over age 50, because tear production tends to decreased as you age
  • Being female, especially if hormonal changes are occurring due to pregnancy, using birth control pills, or menopause
  • Not eating enough vitamin A, which you can find in carrots, broccoli, and liver
  • Not eating enough omega-3 fatty acids, found mainly in walnuts, fish, and vegetable oils
  • Wearing contact lenses

At-home fixes for dry eyes

There are several ways to help alleviate your irritating symptoms of dry eye, in addition to visiting our eye care center for dry eye treatment. The following tips can be very effective:

  • If your home or office is heated or air-conditioned, the lack of moisture in the air may be your problem. Use a humidifier, or place plants and dishes of water around the room. Keeping a bottle of eye mist handy to spray when your eyes feel dry may also help.
  • When outdoors, wear wraparound sunglasses to protect your eyes from the wind, dust, and sun’s rays – all elements that contribute to dry eye pain.
  • Take care to remove all eye makeup from your lids and lashes nightly, using quality antiseptic wipes that work gently.
  • Change your contact lenses regularly to prevent the buildup of irritating protein deposits. Even better, consider wearing daily disposable lenses instead, or ask about contacts for dry eyes.

Diabetes? Tips to Help Prevent Vision Loss from Diabetic Eye Disease

Get help now to avoid vision damage

Diabetes puts you at an elevated risk for certain eye diseases, including glaucoma, cataracts, diabetic retinopathy. Fortunately, there are ways to lower this risk and help keep your vision clear and healthy. Even if you’ve already been diagnosed with a diabetic eye disease, we can help you reverse the damage and promote healthy vision for the future.

If you have diabetes, following these tips from our Cedar Park eye care specialist will go far towards preserving the health of your eyes and eyesight!

Control your blood sugar levels

When blood sugars rise above the normal parameters (the general aim is to have an A1c at or below 7%, as recommended by your physician), they can affect the shape of your eye’s lens. This can lead to blurred vision, which will return to normal after your blood sugar returns to stable, normal levels. Additionally, high blood glucose can damage your tiny ocular blood vessels, which is a symptom of diabetic retinopathy and can cause vision loss.

Get a yearly comprehensive eye exam

Diabetic eye disease typically presents no symptoms during the early stages. Only a dilated eye exam can detect the signs of a problem on your retinal tissue or optic nerve. By getting an eye exam at our Cedar Park eye care center every year, our optometrist will be able to identify the start of diabetic retinopathy or another condition – and you’ll be able to get treatment as soon as possible, before any damage occurs.

Keep blood pressure and cholesterol at healthy numbers

Both high cholesterol and hypertension can increase your risk for diabetic eye disease. By eating nutritiously, exercising, and making healthy lifestyle choices, you can help keep cholesterol and blood pressure in check – helping your eyes and your general health. Veggies, leafy greens, and fruits all fortify your body with essential vitamins and minerals necessary for healthy vision.

Don’t smoke

Smoking puts you at a significantly higher risk for diabetic retinopathy and other ocular diseases related to diabetes. If smoking is a part of your lifestyle habits, quit as soon as possible to prevent vision loss.

Wear UV protection on your eyes

UV rays endanger the lasting health of your eyes and vision for everyone. If you have diabetes, it’s smart to be extra vigilant about protecting your eyes when you’re outdoors. Choose sunglasses with 100% UVA and UVB protection.

Treat vision damage

If you have been diagnosed with diabetic retinopathy and it has already progressed to the point that it threatens your vision, your eye doctor will likely discuss laser treatment with you. Laser procedures for retinopathy shine a beam of light into the back of your eye to burn or cauterize the leaky blood vessels. The procedure isn’t painful because the retina doesn’t have many nerve endings. Laser treatments are generally very effective at preventing further ocular damage and vision loss.

Don’t delay – book a diabetic eye exam today!

At our Cedar Park eye care office, we use advanced diagnostics to pick up on the signs of diabetic eye disease as soon as possible – so you can benefit from treatment as soon as possible! This is the most reliable way to prevent vision loss from diabetes.

At Lakeline Vision Source, we put your family’s needs first. Talk to us about how we can help you maintain healthy vision. Call us today: 512-918-3937 or book an appointment online to see one of our Cedar Park eye doctors.

What Is 20/20 Vision?

If your last eye exam revealed that you have 20/20 vision, you probably walked out of the eye care center with a big smile! It’s a great feeling to be able to see without eyeglasses or contact lenses. However, did you know that 20/20 vision is not the same as having perfect vision? So what is it?

At Lakeline Vision Source, when Dr. Eric Hammond, OD announces the results of your eye exam, he is reporting on your visual acuity, which is the clarity of your eyesight. These numbers describe how well your eyes can see an object that’s 20 feet away. If you can see it clearly, then your vision is considered “normal” – but not “perfect.” That’s because even if you have 20/20 vision, you could still have problems with peripheral vision, color vision, eye coordination, focusing, or depth perception. To find out your visual acuity and total eye health, book an eye exam with our Cedar Park, Texas , optometrist near you.

How does my eye doctor test visual acuity?

Typically, every eye exam and vision screening includes having you read the Snellen Eye Chart. This diagnostic tool appears as lines of block letters and numbers printed in progressively smaller sizes. The first line will display one huge letter, such as an “E”, and as you move down the chart row by row, the letters get smaller, and there are more of them per line. The lower down on the chart you can read correctly, the closer you are to being diagnosed with 20/20 vision. The bottom row (eight down) is 20/20 vision.

What if I don’t have 20/20 vision?

Don’t worry, you’re in good company! Statistics say that almost half of US adults don’t have 20/20 vision.

Depending on what your visual acuity is, you may need vision correction with prescription eyeglasses, contact lenses, or LASIK refractive surgery, to help you achieve 20/20 vision, or close to it. But not everyone can get to 20/20 – even with corrective treatment. In other words, some people can only see at 60 feet what others with normal vision can see at 20 feet (=20/60 vision). However, that doesn’t mean you can’t see well enough to function. For example:

  • If our eye care professional detects that you have 20/40 vision, it’s still enough to get a driver’s license.
  • If you have 20/80 vision, you should still be able to read headlines in a newspaper and tell the time on an alarm clock placed 10 feet away.
  • If your visual acuity deteriorates to 20/200 vision, you’ll be classified as legally blind.

Can I have better than 20/20 vision?

Sure, especially if you’re a bird of prey! Falcons see about eight times better than humans, with a visual acuity of about 20/2. All jokes aside, even humans can have vision that’s sharper than 20/20, such as 20/15. That means you can back up five feet during your eye exam and still read the Snellen eye chart the same as a person with normal vision standing five feet closer to the chart.

Why do I need good vision?

There are lots of reasons why it’s smart to invest in good vision by visiting our Cedar Park eye care center near you for regular eye exams. Don’t underestimate the value of sharp, healthy vision in your life! Here are a few important benefits of 20/20 vision:

  • Reading with ease: reading is essential for day-to-day life, whether you read the newspaper, your smartphone, documents at work, letters and bills, or just want to enjoy a good novel.
  • Comfort: without sharp vision, you’ll need to squint all the time, leading to headaches and muscle strain.
  • Safety: activities such as driving and biking become extremely hazardous if you can’t see. Even if you’re just taking a walk, having sharp visual acuity will help prevent you from tripping and falling.
  • Quality of life: clear eyesight goes far towards your quality of life! Without sharp vision, who knows what scenes and wonderful moments you’ll miss out on?

At Lakeline Vision Source, we’ll help you to see the best that you can see! Contact our Cedar Park, Texas , optometrist to schedule an eye exam near you today.

You Feel Chilled, But Your Eyes Are On Fire!

8 Causes of Burning Eyes and Blurry Vision

You’re probably familiar with the feeling of burning or stinging eyes, but you may not always know what’s causing this irritation. A variety of causes can be behind this type of pain. To pinpoint the exact culprit, visit our Cedar Park, Texas , eye doctor for an eye exam. To prepare you for your visit to Lakeline Vision Source, here’s a heads up about the possible diagnoses that you may hear:

1. Eye Allergies

Allergic conjunctivitis, which is a type of pink eye caused by allergens, is a classic cause of burning eyes. Allergens, such as pollen, dust, and pet dander, irritate the delicate membrane that covers both the inside of your eyelids and your eyes. Just like in all allergies, your body overreacts to a harmless substance that triggers an immune response. To protect your body from what it perceives as a health threat, your immune system releases antibodies (immunoglobulin) that travel through your body releasing chemicals that prompt an allergic reaction – giving you burning eyes often accompanied by itching.

2. Dry eyes

In general, eyes burn when they dry out, and vision can be blurry. How and why do dry eyes happen? The healthy eye surface is coated in a lubricating tear film that has three layers: a mucous layer that helps to disperse tears evenly, a thick and watery middle layer, and an outer layer that has an oily composition. This oily outer surface is essential for preventing evaporation of the water layer. The oil comes from sweat glands in your eyelids that are stimulated by blinking. That’s why blinking can often clear your fuzzy vision. However, if your oil glands get blocked, blinking becomes less effective, and the tears can dry out. The outcome is burning eyes that blinking can’t alleviate.

3. Eye contact with a foreign substance

We’re constantly touching our face and rubbing our eyes, which makes it easy to put your eyes in contact with a number of offensive substances, such as moisturizers, soap, sunscreen, chlorine, spices, and any residue on your fingers. Even your most expensive face wash or flecks of makeup can cause extreme eye irritation. If your eyes suddenly flare up in pain, pay attention to any new products you started using.

4. Blepharitis – eyelid inflammation

One symptom of blepharitis is a gritty sensation and/or burning eyes. This eyelid inflammation can make your eyelids red, crusty, and itchy. It can stem from a bacterial infection, an allergic reaction to makeup, or other health conditions such as rosacea.

5. Sunburnt eyes

You may not have known this, but your eyes can get a sunburn. Known as photokeratitis, sunburnt eyes occur due to overexposure to UV rays, usually from the sun. These dangerous rays can damage your cornea and conjunctiva, causing burning eyes and blurry vision (among other more serious symptoms).

6. Overuse of contact lenses

Wearing your contact lenses for too long can lead directly to eye pain, including stinging eyes and blurry vision that’s so bad you can’t read the page in front of you.

7. The common cold

Certain viruses, such as the common cold or the flu, can also lead to burning eyes.

8. Uveitis or orbital cellulitis

These serious sight-threatening conditions are uncommon, but burning eyes are one of the warning signs. That’s why it’s so important to visit our Cedar Park, Texas , eye doctor for a precise diagnosis of what’s causing your symptoms – so you can get treatment before any vision damage has occurred.

When to Call Your Cedar Park Optometrist

Contact your eye doctor immediately if you experience any of the following symptoms along with burning or stinging eyes:

  • Pain
  • Excessive light sensitivity
  • Oozing discharge from your eye
  • Blurry vision
  • Eye floaters or flashes of light
  • Double vision

Also, if your burning eyes continue for more than a few days – even without any of the above symptoms, contact us at Lakeline Vision Source to book an urgent eye exam.

VR Goggles Safety Guide for Your Vision

Learn how to use the Oculus and protect your eyes from Computer Vision Syndrome & blue light

Virtual reality goggles are rapidly becoming the hottest must-have gaming device. They immerse you fully into a different world, a fantastic realm. And let’s face it, who doesn’t want to be transported to a new and fascinating place?

All you need to do is put a pair of VR goggles over your eyes and you can dash around, battle the enemy, race, and fly away.

However, we also need to face reality and consider the safety of these clever VR goggles, such as the Oculus. Our Cedar Park, Texas , addresses your questions about the effects of this technology on vision and long-term eye health.

Do VR goggles lead to computer vision syndrome (CVS)?

Most types of VR headsets contain LCD monitors that project images at each eye, and the resulting stereoscopic effect creates an illusion of 3D. In order to accomplish this, the monitors must be placed very close to the eyes. As a result, eye strain and the irritating symptoms of CVS are a real-world concern.

Also, especially with young kids who tend to wear headsets like the Oculus for hours on end, prolonged exposure to this unnatural visual position can interfere with the healthy development of focusing, depth perception, and tracking.

Another common symptom of CVS that may occur is “cybersickness”, a type of motion sickness characterized by dizziness and nausea that can continue to disturb you even after you remove the VR goggles. It results from the mismatch of visual information and body posture.

In an interesting twist, while the bothersome and unhealthy symptoms of CVS are definitely a concern, VR goggles can also be used to enhance vision development. When used under the guidance of a qualified optometrist, some VR goggles can improve visual acuity, strengthen eye muscle weakness, and boost eye-hand coordination, reaction time, eye coordination, and depth perception.

What about blue light and CVS?

The jury is still out about the long-term effects of HEV (high energy visible light), also known as blue light, but research indicates that it may raise your risk of developing eye disease in the future. In addition, blue light flickers – which can stress your eyes and lead to headaches and other problems associated with CVS.

Fortunately, these fears about the hazards of blue light don’t have to get in the way of your high-tech leisure. Newer VR goggles are available with protective blue light filters built-in to the lens. Ask our team Lakeline Vision Source about the latest, eye health friendly VR headsets.

How can you enjoy VR and avoid CVS?

Taking a few precautions can enable you to embrace the innovative tech of virtual reality and keep your vision safe. Our Cedar Park, Texas , eye doctor shares these tips:

  • Limit your (and your kid’s) time wearing the Oculus and exploring VR. Play for a half-hour at a time, and take a break every 5 minutes to walk around and reestablish your equilibrium.
  • Choose a slow speed for your main character and avoid making any quick or sudden movements within your VR world
  • Adjust the lenses of your VR goggles to meet the particular needs of your eyes.
  • Set your VR goggles for low brightness and a comfortable contrast
  • Don’t use headsets like the Oculus when you’re feeling sleepy or under the influence of alcohol, medication, or other drugs

Real-life Eye Exams are Essential for Your Eye Care

Is School Work Causing Computer Vision Syndrome in Your Child?

Eye health tips for students from our Cedar Park eye doctor

The start of fall means back-to-school for kids of all ages – and our team at Lakeline Vision Source wishes everyone a smooth and successful return to the classroom!

When your child enters school after a summer of outdoor fun, many of the summer’s vision hazards are left behind. Yet, that doesn’t mean all eye health risks are eliminated! Nowadays, the majority of learning is computer based – exposing students’ eyes to the pain and dangers of blue light and computer vision syndrome. Fortunately, a variety of helpful devices and smartphone apps are available to block blue light and keep your child’s vision safe and comfortable.

To help you safeguard your child’s vision for the upcoming semesters and the long term of life, our Cedar Park optometrist explains all about computer vision syndrome and how to prevent it.

Symptoms of computer vision syndrome

It’s smart to familiarize yourself with the signs of computer vision syndrome. If your child complains about any of these common symptoms, you can help prevent any lasting vision damage by booking an eye exam with our Cedar Park eye doctor near you:

  • Eye irritation and redness
  • Neck, shoulder and back pain
  • Blurry vision
  • Dry eyes, due to reduced blinking
  • Headaches

Basics of blue light

Students spend endless hours in front of digital screens, be it a computer monitor, tablet, or smartphone. There is homework to be done, research to be conducted, texting with friends, and movies and gaming during downtime. All of this screen time exposes your child’s eyes to blue light.

Many research studies have demonstrated that flickering blue light – the shortest, highest-energy wavelength of visible light – can lead to tired eyes, headaches, and blurry vision. Additionally, blue light can disrupt the sleep/wake cycle, causing sleep deprivation and all the physical and mental health problems associated with it. As for your child’s future eye health, blue light may also be linked to the later development of macular degeneration and retinal damage.

How to avoid computer vision syndrome

Our Cedar Park eye doctor shares the following ways to block blue light and protect against computer vision syndrome:

  • Computer glasses, eyeglasses lenses treated with a blue-light blocking coating, and contact lenses with built-in blue light protection are all effective ways to optimize visual comfort when working in front of a screen. These optics reduce eye strain and prevent hazardous blue-light radiation from entering the eyes.
  • Practice the 20-20-20 rule; pause every 20 minutes to gaze at an object that’s 20 feet away for 20 seconds. This simple behavior gives eyes a chance to rest from the intensity of the computer or smartphone screen, preventing eye fatigue.
  • Prescription glasses can be helpful when using a computer for long periods – even for students who don’t generally need prescription eyewear. A weak prescription can take the stress off of your child’s eyes, decreasing fatigue and increasing their ability to concentrate. Our Cedar Park optometrist will perform a personalized eye exam to determine the most suitable prescription.
  • Moisturize vision with eye drops. One of the most common symptoms of computer vision syndrome is dry eyes, namely because people forget to blink frequently enough. Equip your child with a bottle of preservative-free artificial tears eye drops (available over the counter) and remind them to blink!
  • Blue light filters can be installed on a computer, smartphone, and all digital screens to minimize exposure to blue. A range of helpful free apps are also available for download.
  • Limit screen time for your child each day, or encourage breaks at least once an hour. Typically, the degree of discomfort from computer vision syndrome is in direct proportion with the amount of time your child spends viewing digital screens.
  • Set the proper screen distance. Younger children (elementary school) should view their computer at a half-arm’s length away from their eyes, just below eye level. Kids in middle school and high school should sit about 20 – 28 inches from the screen, with the top of the screen at eye level.

For additional info, book a consultation and eye exam at Lakeline Vision Source

When you and your child meet with our Cedar Park eye doctor, we’ll ask questions about your child’s school and study habits to provide customized recommendations on the most effective ways to stay safe from computer vision syndrome and blue light. Our optometrist stays up-to-date with the latest optic technologies and methods to prevent painful vision and eye health damage from using a computer, so you can depend on us for contemporary, progressive treatment.
