Are there ever days when you leave your disposable contact lenses in for just a few days extra? It goes without saying that things are in their best condition when they haven't been used too much. It's no surprise that the same principle can be used to understand the importance of changing your lenses. As a rule, you shouldn't keep your contacts in your eyes longer than you need to. Of course, it might seem harmless, but if you want your eyes to look healthy, keep to the lens regime that your eye care professional decides on. So, if your optician tells you to change them daily, change them daily, because they can't withstand extended wear.
You might think, would it be so bad if I got two or three additional days out of them? To answer this, let's talk about 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 gradually accumulates on your lenses and forms a thin haze. Foggy vision is just the initial result.
After some time, these proteins evolve and make your immune system think the buildup is something foreign, and the body's reaction can lead to eye irritation, itching and redness. This leads to a situation where your eyesight suffers. Even when you do all you can to take good care of your contact lenses, as time goes on, they'll become less smooth and clear, just due to regular deterioration.
The best thing to do is commit to the routine your eye care professional determines for you. When you dispose of and replace your lenses when you're told to, you will never even see the difference that becomes quickly apparent when you wear them any longer than you're meant to.
