If wear contact lenses, then you have probably heard many times that you have to keep them clean when wearing them. This means washing them each day so that dust, bacteria, and other debris does not get into your eye. There are two types of contact lenses, those that can be used for a few months, and those that are disposable. Disposable contact lenses are becoming more popular because they do not have to be washed. You can keep them in your eye for a certain amount of time and then you can throw them away. But for those who do not have disposable lenses, cleaning them each day is important.
