Are there ever days when you leave your disposable contact lenses in for a little too long? It's common knowledge that lots of things are at their best when they haven't been used too much. Well, the same can also help you understand how often you should change your contacts. There is no shortage of reasons not to leave your lenses in for any longer than you've been advised to. Although you might be tempted, if you want your eyes to look healthy, stick to the replacement and wearing timetable given to you by your optometrist. This means that if your optician tells you to use a new pair every two weeks, then change them every two weeks, because they're not made to withstand reuse.
You might think to yourself, is it so bad to get just a couple 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 builds up gradually on your lenses, creating a mild haze. Foggy vision is just the initial result.
After some time, 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 eye irritation, itching and redness. Which means your eyesight suffers. 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, due to normal wear and tear.
It's smart to stick to the schedule your eye care professional advises for you. When you dispose of and replace your lenses when you're told to, you'll never notice the difference that is so obvious when you wear them any longer than you're meant to.
