Fresh Lenses: Why?

Have you ever left your disposable contact lenses in for a little too long? It's a fact of life that lots of things are in in top form when they are fresh. You won't be surprised to hear that the same principle can also help you understand how often you should change your lenses. You should never leave your lenses in your eyes for longer than you're supposed to. Of course, it might seem okay to wear them just one more time, if you care about your eyes, don't overlook the replacement and wearing timetable your optician determines. This means that if your optician tells you to change them daily, change them daily, because they can't withstand extended wear.

So many people think, can't I just squeeze a few more days out of them? To explain this, let's talk about protein - not the type you stir into your shakes, but the natural protein in your eyes that builds up gradually on your lenses and forms a mild haze. Blurry vision is only the first symptom.

Sooner or later, these proteins change form and confuse your immune system, which begins to think that the formation is something foreign, and this can lead to inflammation in the eye. And when this occurs, you won't be seeing your best. Dust and pollen also build up on the lens, slowly make it less clear. But even when people take great care of their contacts, sooner or later they'll become less smooth and clear, which is the result of normal wear and tear.

So basically, it's best to keep to the schedule your optician has instructed you to. Everyone's eyes are different, so only your optometrist should determine the right contact lens replacement routine for you. When you throw out and replace your contact lenses on schedule, you'll never even see the difference that becomes so apparent when you wear them for longer than you're supposed to.
