Why does the edge of contact lens always break?
Contact lenses are fragile and easy to be damaged, especially at the edge. If you don't pay attention to them, you may get scratches or cracks. The surface of the damaged lens is no longer smooth, and the sense of friction in the eyes increases, which makes people feel that there are foreign matters, and it will also cause great damage to the eyes. So, how are these damages caused and how can they be prevented?
Contact lenses with poor quality usually have low strength and are prone to rupture. The best way is to replace a new pair of lenses. The use of unqualified nursing liquid products will also affect the quality of lenses. Sales of contact lenses and their supporting products need to have the corresponding qualifications, purchase to choose a regular shop with a license.
When operating the lens, the action must be gentle, and the lens may be damaged inadvertently due to hard scrubbing or too long fingernails. When using tweezers, do not take off the rubber head, otherwise the lens will be scratched.
Contact lenses become brittle and hard when dehydrated, so they must be kept moist at all times. When not wearing, put it into the glasses box and keep it in the care solution. It should be noted that the care solution in the glasses box should not exceed two thirds, and the lens should not float on the surface of the care solution, so as to prevent the lens from breaking when the cover is covered.
When using contact lenses, be sure to handle the lenses carefully to prevent damage caused by violent operation. And as long as the lens is slightly scratched or damaged, it can no longer be worn. Because the surface tension of the lens changes at this time, it is relatively easier to break, and it will also wear the eyeball and cornea, breed bacteria and cause infection, and ultimately cause incalculable damage to the eyes.
