Have you ever left your soft contact lenses in for longer than you're supposed to? It's a basic fact that lots of things are a whole lot better when they are fresh. It's no surprise that the same also applies to your contacts. It's a bad idea to leave your lenses in your eyes for longer than you're supposed to. Despite that fact that it might seem okay, if you want your eyes to see their very best, don't ignore the lens timetable given to you by your optometrist. So, if your optician tells you to change them monthly, then change them every month, because they can't withstand extended wear.
You might ask, would it be so bad if I got a few additional days out of them? To better comprehend this, let's talk about protein - and not the kind inside your burger, but the natural protein that is a main component of the tears and eye fluids that gathers over time on the surface of your lenses and creates a mild haze. Foggy vision is only the first symptom.
Eventually these proteins transform and trick your immune system into thinking the formation is something foreign, and this can lead to inflammation in the eye. Which means you won't be seeing your best. External elements like pollen or dust can also build up on the lens, which also makes vision blurry. But even when people take great care of their contacts, as time passes, they'll become less smooth and clear, due to normal wear and tear.
So basically, it's best to stick to the routine your optometrist advises for you. Nobody has the same eyes, so only your optometrist should decide on the correct contact lens replacement routine for you. When you replace your contact lenses when you're told to, you will never even see the difference that is so obvious when you overwear them.
