Have there been times when you've left your soft contact lenses in for just a few days longer than your optometrist instructs? It's a basic fact that things are a whole lot better when they're new. You won't be surprised to hear that the same rule also applies to your lenses. It's a bad idea to keep them in your eyes longer than you've been advised to. Even though it might seem okay to wear them just one more time, if you want to help your eyes stay healthy, don't overlook the lens timetable your optician gives you. This means that if your optician tells you to use a new pair monthly, then change them every month, because they're not made to be worn any longer than they're supposed to.
A lot of people think to themselves, can't I get a few more days out of them? To better comprehend this, let's talk about protein - not the type you stir into your shakes, but the natural protein in your eyes that gradually accumulates on the surface of your lenses which forms a thin haze. Blurry eyesight is just the beginning.
Eventually these proteins evolve and confuse your immune system, which begins to think that the buildup is something foreign, and the body's reaction can be expressed as eye irritation, itching and redness. Which means your eyesight suffers. But even when people take great care of their contacts, sooner or later they stop being as clear and smooth, due to normal deterioration.
It's best to adhere to the routine your eye care professional determines for you. When you dispose of and replace your lenses when you're told to, you'll never even see the difference that is so obvious when you use them longer than you're supposed to.
