Have you ever left your disposable contact lenses in for just a few days extra? It goes without saying that generally, things are just plain better when they haven't been used too much. It's helpful to know that the same can also help you understand how often you should change your contact lenses. There are so many reasons why you shouldn't keep your lenses in for any more time than necessary. Although you might be tempted to use them just one more time, if you want to help your eyes stay healthy, don't overlook the wearing and changing schedule recommended to you by your optician. In other words, if your optician tells you to replace them monthly, then change them every month, because they're not made to withstand reuse.

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 the surface of your lenses which forms a mild haze. Blurry vision is just the start.
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 result in inflammation in the eye. And when this occurs, your eyesight suffers. Dust and pollen also build up on the lens, slowly make it less clear Even when you're thorough about caring for your contacts, eventually they'll become less smooth and clear, which is the result of normal wear and tear.
