Contact lenses are designed to improve a person’s vision, but if not used properly they can also hurt your eyes.
The most common mistakes are people sleeping while wearing contact lenses that are not designed for overnight use, as well as users not replacing lenses when they’ve hit their expiration date. The most common problem they see is people wearing their contact lenses for too long. Contact lenses may still feel comfortable after their two-week or one-month recommended stint, so people continue to wear them. Contact lenses should be discarded when they expire regardless of how they feel.
However, said the most dangerous mistake people make is to “top off” solutions used to clean contact lenses. Leaving even a small amount of old solution in a lenses case and then putting in new solution can create problems. Among them is the fact the mixed solution can dilute the liquid’s ability to kill germs. It is recommended emptying any old solution and then letting the contact case dry before adding new solution.
The first is not to sleep with your contact lenses in, it can increase the risk of infection by 6 to 8 times. The contact lens solution should never be topped off. “Adding new solution to used solution can lower germ-killing power” . The third suggestion is to replace contact lenses as recommended by your eye doctor.
