Contact lens infection is a condition where harmful microorganisms, such as bacteria, fungi, and viruses, infect the eye through contact lenses. If left untreated, contact lens infection may be very painful and, depending on their origin and severity, result in vision loss and even blindness.
The most common infection brought on by contact lenses are corneal infections (keratitis), which affects the transparent dome that covers the pupil and iris in front of the eye. For worse cases, contact lens infection may cause scarring in the cornea. Such severe case may require corneal transplant if it causes total vision loss.
