Do you ever end up leaving your soft contact lenses in for just a few days longer than your optometrist instructs? It's a pretty accepted fact that lots of things are just plain better when they haven't been used too much. Well, the same idea can also help you understand how often you should change your lenses. There are so many reasons why you shouldn't leave them in for longer than you're supposed to. Despite that fact that it might seem okay to use them just one more time, if you want your eyes to see their very best, follow the replacement and wearing schedule recommended to you by your optician. This means that if your optician tells you to change pairs every two weeks, then change them every two weeks, because they can't be worn any longer than that.
A lot of people think to themselves, is it so bad to get just a few more days out of them? To answer this, let's talk about protein - not the type you stir into your shakes, but the natural protein in your tears that builds up gradually on the surface of your lenses and forms a light haze. Unclear vision is just the start.
After some time, these proteins transform and make your immune system think the buildup is something foreign, and this can result in eye irritation, itching and redness. This leads to a situation where your eyesight suffers. Dust and pollen also build up on the lens, slowly make it less clear. But even when people take great care of their contacts, over time they stop being as smooth and clear, due to normal deterioration.
It's best to keep to the plan your optician has instructed you to. When you dispose of and replace your lenses on schedule, you will never detect the difference that is so obvious when you overwear them.
