Are you someone who leaves your soft contact lenses in for more time than recommended? We don't need to tell you that lots of things are a whole lot better when they're new. It's helpful to know that the same can be used to understand the importance of changing your lenses. It's a bad idea to keep your contacts in longer than you need to. Even though it might not seem so bad, if you want to help your eyes stay healthy, don't ignore the replacement schedule your optician determines. This means that if your optometrist tells you to change pairs monthly, then change them every month, because they're not made to withstand reuse.
You might think, would it be so bad if I got two or three extra days out of them? To answer this, let's examine protein - not the dietary kind, but the natural protein found in your tears that gathers over time on the surface of your lenses which forms a light haze. Unclear vision is just the start.
If this continues, these proteins evolve and make your immune system think the formation is a foreign particle, and the body's reaction can be expressed as inflammation in the eye. 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 vision blurry. Even when you're thorough about caring for your contacts, over time they'll become less clear and smooth, which is the result of normal wear and tear.
So basically, it's best to stick to the plan your optometrist has instructed you to. Everyone's eyes are unique, so only your eye care professional should determine the best contact lens replacement routine for you. When you change your lenses at the correct times, you'll never notice the difference that is so apparent when you overwear them.
