Are you someone who leaves your soft contact lenses in for an extra few days? We don't need to tell you that so many things are in in top form when they're fresh. Well, the same idea can be used to understand the importance of changing your lenses. There is no shortage of reasons not to keep your lenses in your eyes for any more time than you've been instructed to. Although it might be tempting to use them just one more time, if you care about having healthy eyes, stick to the lens timetable given to you by your optometrist. So, if your optician tells you to change them every two weeks, then change them every two weeks, because they're not made to withstand reuse.
You might ask, is it so bad to get just a few more days out of them? To better comprehend this, let's talk about protein – and not the kind inside your burger, but the natural protein that is a main component of the tears and eye fluids that gradually accumulates on the surface of your lenses which forms a mild haze. Unclear vision is just the start.
As time goes on, these proteins change form and make your immune system think the accumulation is a foreign particle, and this can result in inflammation in the eye. This leads to a situation where a toll is taken on your vision. External particles like pollen or dust can also build up on the lens, which also makes eyesight less clear. Even if you take perfect care of your contacts, eventually they stop being as smooth and clear, due to normal deterioration.
So commit to the routine your eye care professional advises for you. Everyone's eyes are different, so only your optometrist should determine the correct contact lens replacement routine for you. When you dispose of and replace your contact lenses on time, you'll never detect the difference that is so obvious when you overwear them.
