Fresh Contact Lenses: Why?

Are there ever days when you leave your disposable contact lenses in for longer than you're supposed to? It's a pretty accepted fact that things are at their best when they haven't been used too much. Guess what? The same principle is also applicable to your lenses. There are so many reasons why you shouldn't keep them in for any longer than you've been instructed to. Despite that fact that it might seem okay to use them just one more time, if you want your eyes to look healthy, don't overlook the replacement and wearing routine your eye doctor gives you. In other words, if you've been instructed to wear a new pair monthly, then change them every month, because they can't be worn any longer than that.

You might think, can't I just squeeze a few extra wears out of them? To answer this, all us to look at protein - and we don't mean the kind you eat, but the natural protein that is a main component of the tears and eye fluids that gathers over time on the surface of your lenses, forming a light haze. Blurry eyesight is just the beginning.

If this continues, these proteins transform and confuse your immune system, which begins to think that the formation is something foreign, and the body's reaction can lead to itchy, swollen and irritated eyes. This leads to a situation where you won't be seeing your best. Even when you're strict about caring for your contacts, sooner or later they stop being as clear and smooth, just due to regular wear and tear.  Soft contact lenses are made of different materials with different contours and lens thickness.  Your eye doctor ensures proper initial fit of the lenses.  However, the soft lens does not always hold its original shape, and can "warp" with handling.  Overwearing a lens that does not fit properly anymore can cause damage to the eye. Seasoned contact lens wearers may not know this, as they have adapted to the feeling of the contact lenses.  So even if the lenses "feel" comfortable, ensure that the eyes are still bright, white and healthy by regular contact lens checkups.

So adhere to the plan your eye doctor determines for you. Everyone's eyes are unique, so only your optometrist should decide on the correct contact lens replacement routine for you. When you dispose of and replace your lenses when you're told to, you will never even recognize the difference that becomes so apparent when you use them longer than you're supposed to.
