Are there ever days when you leave your disposable contact lenses in for just a few days extra? It's common knowledge that things are a whole lot better when they are fresh. It's no surprise that the same can also help you understand how often you should change your lenses. There is no shortage of reasons not to keep your lenses in for longer than you've been instructed to. Even though it might seem okay to wear them just one more time, if you want to help your eyes stay healthy, follow the replacement schedule your optician gives you. So, if you're told to wear a new pair 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 extra days out of them? To better comprehend this, let's talk about protein - not the type you stir into your shakes, but the natural protein in your eyes that builds up gradually on the surface of your lenses, forming a thin haze. Unclear vision is only the first symptom.
Eventually these proteins evolve and make your immune system think the buildup is something foreign, and this can result in eye irritation, itching and redness. This leads to a situation where you won't be seeing your best. Dust and pollen also build up on the lens, slowly make it less clear Even if you take perfect care of your contacts, over time they'll become less smooth and clear, which is the result of normal deterioration.
It's best to adhere to the schedule your optician has instructed you to. Everyone's eyes are different, so only your optometrist should determine the right contact lens replacement routine for you. If you replace your contact lenses on schedule, you will never even see the difference that is so obvious when you overwear them.
