Have there been times when you've left your disposable contact lenses in for just a bit too long? Everyone knows that generally, things are better when they haven't been used too much. It's no surprise that the same idea can be used to understand the importance of changing your contacts. As a rule, you shouldn't leave your lenses in for longer than necessary. Of course, it might be tempting, if you want to help your eyes stay healthy, keep to the lens schedule your optician determines. This means that if you're told to use a new pair daily, change them daily, because they can't withstand reuse.
So many people think, is it so bad to get just a couple additional days out of them? To explain this, let's take a look at protein - not the type you stir into your shakes, but the natural protein in your eyes that slowly accumulates on your lenses and creates a mild haze. Blurry vision is just the beginning.
Sooner or later, these proteins transform and confuse your immune system, which begins to think that the buildup is a foreign particle, and the body's reaction can lead to inflammation in the eye. 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 sight less clear. But even when people take great care of their contacts, eventually they'll become less smooth and clear, due to normal wear and tear.
So basically, it's best to keep to the routine your optician has instructed you to. If you throw out and replace your lenses on schedule, you'll never even recognize the difference that is so apparent when you use them longer than you're supposed to.
