blue light

Why Are Blue Eyes More Sensitive To Light?

Did you know that blue eyes don’t contain any blue pigment? They appear blue due to how the light reacts with the structures of the iris.

In fact, the top layer of a blue iris doesn’t contain any pigment at all. This lack of pigment is the reason that blue-eyed people may be more sensitive to bright light and have a greater need to wear sunglasses than their brown-eyed counterparts.

Why Do Your Eyes Need Sun Protection?

Eyes of all colors need shielding from the sun’s harmful ultraviolet (UV) rays. Exposure to UV light can contribute to the formation of short-term and long-term eye conditions such as corneal sunburn and macular degeneration.

That’s why it’s so important to choose high-quality sunwear with 100% UV blocking lenses, and to throw on a sun hat for an added layer of protection.

UV protection is important for individuals of all ages—especially children—who are more susceptible than adults to the sun’s harmful rays, and tend to spend more time outdoors. It is estimated that up to 80% of a person’s lifetime exposure to UV rays happens before the age of 18.

Why are Blue Eyes More Sensitive to Light?

Lighter colored eyes like blue, hazel and green have less of a pigment called ‘melanin’ than brown eyes do.

Melanin helps protect the retina from UV damage and blue light, putting those with blue eyes at a higher risk of developing UV-related eye damage.

If you have blue eyes, you may have experienced this first-hand. Bright light may be uncomfortable or you may want to reach for your shades as soon as you leave the house on a sunny day.

That’s why optometrists urge blue-eyed patients to be particularly vigilant about UV protection, so as to mitigate their chances of developing eye disease and other complications.

Q&A:

Frequently Asked Questions with Eric Hammond OD

Q 1: Should I wear sunglasses even when it’s not sunny outside?

  • A: Yes! You should wear your sunglasses whenever outdoors during the day, even on an overcast, winter day. UV light can pass through clouds and reflect off surfaces like car windows and pavement.

Q 2: What type of sunglasses are the most suitable for blue eyes?

  • A: The most protective sunglasses are wraparound sunglasses that protect the eyes from every angle. You can also opt for photochromic lenses, which offer total UV protection but only become tinted when exposed to outdoor sunlight, and turn clear when you come indoors again. Your optometrist can help you choose the best lens and frame options for your needs and lifestyle.

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

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.
