Have there been times when you've left your soft contact lenses in for more time than recommended? Everyone knows that a lot of things are in their best condition when they're fresh. It's important to know that the same rule is also applicable to your contact lenses. There is no shortage of reasons not to keep them in for any longer than you've been instructed to. Although it might seem okay, if you care about your eyes, don't ignore the lens schedule your optician gives you. In other words, if you've been instructed to wear a new pair every two weeks, then change them every two weeks, because they can't be worn any longer than that.
So many people think, can't I just squeeze a couple 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 builds up gradually on the surface of your lenses, creating a thin haze. Blurry vision is just the initial result.
If this continues, these proteins evolve and trick your immune system into thinking the buildup is a foreign particle, and this can result in eye irritation, itching and redness. This leads to a situation where a toll is taken on your vision. External elements like pollen or dust can also build up on the lens, which also makes sight blurry. But even when people take great care of their contacts, as time passes, they stop being as clear and smooth, just due to regular deterioration.
The best thing to do is adhere to the plan your optician advises for you. Everyone's eyes are different, so only your eye care professional should determine the right contact lens replacement schedule for you. If you dispose of and replace your contact lenses on schedule, you'll never even see the difference that becomes quickly apparent when you wear them any longer than you're meant to.
