Are you someone who leaves your soft contact lenses in for just a few days longer than your optometrist instructs? It goes without saying that things are in in top form when they're new. You won't be surprised to hear that the same rule can be used to understand the importance of changing your contact lenses. It's not a good idea to leave your contacts in your eyes for any more time than you need to. Of course, it might not seem so bad to wear them just one more time, if you care about having healthy eyes, adhere to the lens regime your optician gives you. In other words, if your optician tells you to change pairs daily, change them daily, because they're not made to withstand reuse.
You might think to yourself, can't I get two or three extra days out of them? To understand this idea, let's take a look at protein – and not the kind inside your burger, but the natural protein in your eyes that gathers over time on your lenses which forms a mild haze. Blurry vision is only the first symptom.
As time goes on, these proteins transform and make your immune system think the formation is something foreign, and the body's reaction can be expressed as itchy, swollen and irritated eyes. And this means that you won't be seeing your best. Dust and pollen also build up on the lens, slowly make it less clear. But even when people take great care of their contacts, sooner or later they'll become less clear and smooth, just due to regular deterioration.
It's best to commit to the routine your optometrist determines for you. When you change your contact lenses when you're told to, you'll never even recognize the difference that becomes quickly apparent when you wear them for longer than you're supposed to.
