How often do you leave your disposable contact lenses in for an extra few days? It's a fact of life that so many things are in their best condition when they haven't been used too much. It's important to know that the same rule also applies to your lenses. As a rule, you shouldn't leave your lenses in your eyes for any more time than you need to. Of course, it might seem harmless to use them just one more time, if you want your eyes to see their very best, follow the replacement timetable that your eye care professional decides on. So, if your optometrist tells you to change them daily, change them daily, because they can't be worn any longer than that.
You might ask, can't I get a couple more days out of them? To explain this, let's take a look at protein - and not the kind inside your burger, but the natural protein that is a main component of the tears and eye fluids that builds up gradually on the surface of your lenses which forms a light haze. Unclear vision is just the start.
Over time, these proteins evolve and confuse your immune system, which begins to think that the accumulation is something foreign, and the body's reaction can be expressed as itchy, swollen and irritated eyes. This leads to a situation where your eyesight suffers. Dust and pollen also build up on the lens, slowly make it less clear Even if you take the best possible care of your contacts, over time they'll become less smooth and clear, which is the result of normal wear and tear.
The best thing to do is stick to the routine your optician has instructed you to. Nobody has the same eyes, so only your eye care professional should decide on the correct contact lens replacement schedule for you. When you change your lenses at the correct times, you'll never even see the difference that becomes so apparent when you wear them for longer than you're supposed to.
