Do you ever end up leaving your disposable contact lenses in for just a few days extra? It's a fact of life that things are a whole lot better when they're new. It's no surprise that the same rule is also applicable to your lenses. As a rule, you shouldn't leave your contacts in for longer than you need to. Even though it might seem harmless, if you want your eyes to look healthy, don't ignore the lens routine recommended to you by your optician. So, if your optometrist tells you to replace them daily, change them daily, because they're not made to withstand reuse.
You might think, can't I get a couple extra wears out of them? To understand this idea, let's take a look at protein – not the type you stir into your shakes, but the natural protein in your tears that gradually accumulates on the surface of your lenses, forming a light haze. Blurry vision is just the start.
After some time, these proteins transform and trick your immune system into thinking the formation is a foreign particle, which in turn can be expressed as itchy, swollen and irritated eyes. And this means that your eyesight suffers. Dust and pollen also build up on the lens, slowly make it less clear. But even when people take great care of their contacts, over time they stop being as smooth and clear, due to normal wear and tear.
The best thing to do is keep to the routine your eye care professional determines for you. Everyone's eyes are unique, so only your eye care professional should decide on the best contact lens replacement routine for you. If you change your lenses when you're told to, you will never even recognize the difference that is so obvious when you overwear them.
