The Importance of Changing Your Contact Lenses

Have you ever left your disposable contact lenses in for just a few days longer than your optometrist instructs? It goes without saying that so many things are better when they haven't been used too much. Guess what? The same rule applies to your contact lenses. You should never keep your contacts in your eyes longer than you're supposed to. Although you might be tempted to use them just one more time, if you care about your eyes, adhere to the lens regime your optician determines. So, if you've been instructed to wear a new pair daily, change them daily, because they can't be worn any longer than that.

You might think, can't I get a few extra days out of them? To explain this, let's take a look at protein - not the dietary kind, but the natural protein in your tears that gathers over time on the surface of your lenses, forming a thin haze. Blurry vision is just the start.

As time goes on, these proteins transform and confuse your immune system, which begins to think that the buildup is something foreign, which in turn can lead to eye irritation, itching and redness. This leads to a situation where your vision won't be working at its best. External particles like pollen or dust can also accumulate on the lens, which also makes eyesight less clear. Even when you're thorough about caring for your contacts, over time they stop being as clear and smooth, due to normal wear and tear.

It's smart to stick to the routine your optician has instructed you to. If you dispose of and replace your contact lenses on schedule, you will never even recognize the difference that becomes quickly apparent when you wear them any longer than you're meant to.
