Do you ever leave your soft contact lenses in for an extra few days? We don't need to tell you that a lot of things are at their best when they are at their freshest. It's important to know that the same can be used to understand the importance of changing your contacts. You should never leave them in for any more time than you're supposed to. Although it might seem okay to wear them just one more time, if you want your eyes to see their very best, adhere to the lens schedule that your eye care professional decides on. This means that if you've been told to replace them every two weeks, then change them every two weeks, because they can't be worn any longer than that.
You might ask, is it so bad to get just two or three more wears out of them? In order to better understand this, let's examine protein - although not the edible sort, but the natural protein in your eyes that gradually accumulates on your lenses which forms a thin haze. Blurry vision is just the beginning.
After some time, these proteins transform and confuse your immune system, which begins to think that the formation is something foreign, which in turn can result in itchy, swollen and irritated eyes. 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, sooner or later they stop being as clear and smooth, just due to regular deterioration.
It's best to commit to the schedule your eye care professional has instructed you to. Everyone's eyes are different, so only your optometrist should decide on the right contact lens replacement schedule for you. If you throw out and replace your contact lenses at the correct times, you will never even recognize the difference that is so obvious when you use them longer than you're supposed to.
