Do you ever end up leaving your disposable contact lenses in for just a few days extra? It's a basic fact that lots of things are just plain better when they are fresh. Well, the same applies to your lenses. You should never keep them in for longer than you've been instructed to. Even though it might seem harmless to use them just one more time, if you want your eyes to look healthy, don't ignore the replacement and wearing regime that your eye care professional decides on. This means that if you've been instructed to change pairs daily, change them daily, because they're not made to withstand reuse.
You might think to yourself, would it be so bad if I got a couple additional days 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 that is a main component of the tears and eye fluids that builds up gradually on the surface of your lenses which forms a mild haze. Blurry eyesight is just the initial result.
Sooner or later, these proteins change form and make your immune system think the accumulation is something foreign, which in turn can be expressed as eye irritation, itching and redness. And this means that a toll is taken on your vision. Dust and pollen also build up on the lens, slowly make it less clear Even when you're strict about caring for your contacts, as time goes on, they become less smooth and clear, which is the result of normal deterioration.
The best thing to do is stick to the schedule your eye care professional determines for you. When you replace your lenses on schedule, you will never detect the difference that is so apparent when you wear them for longer than you're supposed to.
