Have you ever left your soft contact lenses in for just a few days longer than your optometrist instructs? It's common knowledge that things are in their best condition when they haven't been used too much. You won't be surprised to hear that the same rule applies to your lenses. As a rule, you shouldn't keep your lenses in your eyes longer than you've been advised to. Despite that fact that it might seem harmless to use them just one more time, if you care about having healthy eyes, don't overlook the wearing and changing timetable your optician determines. This means that if your optometrist tells you to use a new pair daily, change them daily, because they can't withstand extended wear.
You might think to yourself, would it be so bad if I got two or three additional days out of them? To explain this, let's take a look at protein - although not the edible sort, but the natural protein in your eyes that gradually accumulates on your lenses and forms a light haze. Blurry eyesight is only the first symptom.
Sooner or later, these proteins evolve and confuse your immune system, which begins to think that the formation is a foreign particle, which in turn can be expressed as itchy, swollen and irritated eyes. This leads to a situation where you won't be seeing your best. Other factors can also attribute to this, like the build up of dust or pollen on the lens Even when you do all you can to take great care of your contact lenses, as time goes on, they stop being as smooth and clear, just due to regular wear and tear.
The best thing to do is commit to the plan your optometrist has instructed you to. Nobody has the same eyes, so only your optometrist should determine the best contact lens replacement routine for you. If you throw out and replace your lenses on schedule, you will never even see the difference that becomes so apparent when you wear them any longer than you're meant to.
