Are there ever days when you leave your disposable contact lenses in for too long? It goes without saying that generally, things are just plain better when they haven't been used too much. You won't be surprised to hear that the same rule can be used to understand the importance of changing your lenses. You should never leave them in your eyes for any more time than you're supposed to. Even though you might be tempted to wear them just one more time, if you want to help your eyes stay healthy, adhere to the replacement and wearing routine your optician determines. This means that if your optometrist tells you to replace them monthly, then change them every month, because they're not made to be worn any longer than they're supposed to.
You might ask, can't I just squeeze two or three extra days out of them? To explain this, let's take a look at protein – not the dietary kind, but the natural protein in your tears that gradually accumulates on the surface of your lenses, creating a mild haze. Blurry vision is just the beginning.
Over time, these proteins transform and make your immune system think the formation is a foreign particle, and this can lead to itchy, swollen and irritated eyes. This leads to a situation where you won't be seeing your best. Dust and pollen also build up on the lens, slowly make it less clear Even when you're thorough about caring for your contacts, sooner or later they become less smooth and clear, just due to regular wear and tear.
It's smart to adhere to the plan your optometrist determines for you. When you replace your contact lenses at the correct times, you'll never detect the difference that becomes quickly apparent when you use them longer than you're supposed to.
