How often do you leave your disposable contact lenses in for more time than recommended? Everyone knows that generally, things are at their best when they're new. Guess what? The same principle also applies to your contacts. It's a bad idea to keep your contacts in for any longer than necessary. Of course, it might be tempting, if you want your eyes to see their very best, follow the lens timetable your optician gives you. So, if you're told to change them daily, change them daily, because they're not made to withstand reuse.
You might ask, would it be so bad if I got 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 that is a main component of the tears and eye fluids that builds up gradually on your lenses and forms a light haze. Unclear vision is just the start.
After some time, these proteins evolve and confuse your immune system, which begins to think that the formation is a foreign particle, and the body's reaction can result in eye irritation, itching and redness. And this means that you won't be seeing your best. External particles like pollen or dust can also build up on the lens, which also makes vision blurry. Even if you take perfect care of your contacts, over time they become less clear and smooth, which is the result of normal wear and tear.
So keep to the schedule your eye care professional has instructed you to. Everyone's eyes are different, so only your optometrist should decide on the appropriate contact lens replacement schedule for you. When you change your contact lenses on schedule, you'll never notice the difference that becomes so apparent when you wear them for longer than you're supposed to.
