Are you someone who leaves your disposable contact lenses in for too long? It's a basic fact that things are better when they haven't been used too much. It's helpful to know that the same principle can also help you understand how often you should change your lenses. As a rule, you shouldn't leave them in your eyes longer than you're supposed to. Of course, it might seem harmless to wear them just one more time, if you want to help your eyes stay healthy, adhere to the replacement and wearing regime recommended to you by your optician. So, if you've been told to change them monthly, then change them every month, because they can't withstand reuse.
You might think to yourself, is it so bad to get just a couple additional wears out of them? To understand this idea, let's take a look at protein - although not the edible sort, but the natural protein that is a main component of the tears and eye fluids that gradually accumulates on the surface of your lenses, creating a light haze. Unclear vision is only the first symptom.
After some time, these proteins transform and make your immune system think the formation is something foreign, which in turn can lead to inflammation in the eye. And when this occurs, you won't be seeing your best. Other factors can also attribute to this, like the build up of dust or pollen on the lens But even when people take great care of their contacts, sooner or later they stop being as smooth and clear, which is the result of normal deterioration.
It's best to adhere to the routine your optometrist has instructed you to. Nobody has the same eyes, so only your optometrist should determine the best contact lens replacement schedule for you. If you dispose of and replace your lenses on schedule, you'll never even recognize the difference that becomes so apparent when you wear them any longer than you're meant to.
