Label TextThese lenses are used in eye exams to determine if someone has any optical aberrations. The exam determines what kinds of lenses will be needed if the patient requires eyeglasses. The lenses here have three different shape variations: concave, convex, and cylindrical. Concave lenses are used to correct nearsightedness, convex lenses correct farsightedness, and cylindrical lenses correct astigmatism.
