Are there ever days when you leave your disposable contact lenses in for just a bit too long? It's a basic fact that generally, things are a whole lot better when they are at their freshest. Guess what? The same principle is also applicable to your contact lenses. It's a bad idea to leave them in your eyes for any more time than you're supposed to. Although you might be tempted, if you want your eyes to see their very best, don't overlook the wearing and changing schedule recommended to you by your optician. In other words, if your optician tells you to wear a new pair every two weeks, then change them every two weeks, because they're not made to withstand reuse.
You might think to yourself, is it so bad to get just two or three extra wears out of them? To better comprehend this, let's take a look at protein – and we don't mean the kind you eat, but the natural protein in your tears that gathers over time on the surface of your lenses, forming a mild haze. Blurry eyesight is just the beginning.
As time goes on, these proteins evolve and trick your immune system into thinking the buildup is something foreign, and the body's reaction can result in eye irritation, itching and redness. And this means that you won't be seeing your best. External elements like pollen or dust can also accumulate on the lens, which also makes vision blurry. But even when people take great care of their contacts, over time they stop being as clear and smooth, which is the result of normal deterioration.
It's best to keep to the routine your optometrist has instructed you to. If you dispose of and replace your lenses at the correct times, you will never even recognize the difference that becomes quickly apparent when you wear them for longer than you're supposed to.
