Have there been times when you've left your disposable contact lenses in for just a few days extra? It's a basic fact that so many things are a whole lot better when they're new. It's helpful to know that the same rule applies to your contact lenses. There are so many reasons why you shouldn't keep them in for longer than you're supposed to. Even though it might not seem so bad, if you want your eyes to see their very best, keep to the replacement timetable recommended to you by your optician. So, if your optician tells you to change pairs daily, change them daily, because they can't withstand reuse.
You might think to yourself, would it be so bad if I got a few more wears out of them? To explain this, let's take a look at protein - and not the kind inside your burger, but the natural protein contained in your eye fluids that gathers over time on your lenses which forms a light haze. Foggy vision is just the beginning.
Over time, these proteins evolve and make your immune system think the buildup is something foreign, which in turn can be expressed as inflammation in the eye. This leads to a situation where your vision won't be working at its 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, eventually they become less smooth and clear, which is the result of normal wear and tear.
The best thing to do is commit to the routine your optometrist advises for you. When you change your contact lenses on time, you will never notice the difference that becomes so apparent when you overwear them.
