Doing good jod of contact lenses hygiene is indeed very important for our eyes. This is because that the contact lenses are directly in touch with our eyeballs, which makes it easily for our eyes to get infected by viruses or bacteria if the lenses are not clean. In addition, wearing eye contact lenses can to some extent hinder the normal transportation of the water and oxygen from the air outside the eyes through the cornea, and if the contact lenses are not clean or wearing them for too long, the eyes will get dry and fatigue, or even cause corneal lesion. Also, in some cases the contact lenses which have been put on the front of the eyeballs can move to somewhere else, which can cause friction to the cornea and lead to corneal ulceration. Therefore, you should pay attention to use lens care solution to clean the contact lenses every time before you wear them, and store them in clean lens container filled with fresh care solution everyday after taking them off.
