Are there ever days when you leave your soft contact lenses in for too long? We don't need to tell you that things are at their best when they're new. It's helpful to know that the same rule applies to your contacts. There is no shortage of reasons not to keep them in your eyes for any longer than you've been advised to. Although it might be tempting to wear them just one more time, if you want your eyes to look healthy, adhere to the replacement timetable your optician gives you. In other words, if you've been told to change them every two weeks, then change them every two weeks, because they're not made to be worn any longer than they're supposed to.
You might think, is it so bad to get just a couple more wears out of them? To understand this idea, let's take a look at protein - although not the edible sort, but the natural protein that is a main component of the tears and eye fluids that builds up gradually on the surface of your lenses which forms a thin haze. Unclear vision is just the beginning.
Eventually these proteins transform and confuse your immune system, which begins to think that the buildup is something foreign, and the body's reaction can be expressed as inflammation in the eye. Which means you won't be seeing your best. Dust and pollen also build up on the lens, slowly make it less clear Even when you do all you can to take excellent care of your contact lenses, as time goes on, they become less clear and smooth, just due to regular wear and tear.
So basically, it's best to stick to the schedule your optometrist has instructed you to. Everyone's eyes are unique, so only your eye care professional should determine the right contact lens replacement routine for you. When you dispose of and replace your lenses when you're told to, you will never even see the difference that is so obvious when you wear them any longer than you're meant to.
