Using contact lenses may lead to an eye infection. Contact lenses sit directly on the eye, and if they are not cleaned and stored properly, bacteria can accumulate on the lenses and cause an infection. Symptoms of an eye infection include redness, pain, sensitivity to light, and discharge. To prevent eye infections when wearing contact lenses, it is important to wash your hands thoroughly before handling them, clean and disinfect them regularly, and avoid wearing them for too long or while sleeping. It is also important to follow your eye doctor's instructions for proper use and care of your contact lenses. Convex lenses, biconcave lenses, and concave lenses are not likely to lead to an eye infection, as they are not worn directly on the eye and do not come into contact with it. These types of lenses are used to correct vision problems and do not pose a risk of infection unless they are contaminated and come into contact with the eye.
