Are you someone who leaves your disposable contact lenses in for just a few days longer than your optometrist instructs? Everyone knows that lots of things are just plain better when they are fresh. You won't be surprised to hear that the same principle can be used to understand the importance of changing your contact lenses. It's not a good idea to leave your lenses in your eyes for any longer than you're supposed to. Of course, it might seem okay, if you care about having healthy eyes, don't ignore the replacement timetable given to you by your optometrist. This means that if your optometrist tells you to change them monthly, then change them every month, because they're not made to withstand reuse.
So many people think, can't I get a few more days out of them? To answer this, let's take a look at protein – and not the kind inside your burger, but the natural protein in your eyes that gathers over time on the surface of your lenses and forms a light haze. Blurry eyesight is just the initial result.
Sooner or later, these proteins change form and confuse your immune system, which begins to think that the buildup is a foreign particle, and this can lead to itchy, swollen and irritated eyes. This leads to a situation where a toll is taken on your vision. But even when people take great care of their contacts, sooner or later they become less smooth and clear, just due to regular deterioration.
It's smart to commit to the schedule your eye care professional decides on for you. If you change your lenses on schedule, you will never even see the difference that becomes quickly apparent when you wear them any longer than you're meant to.
