glare, a strong, dazzling light that may cause discomfort to the eye. Visual problems that result from glare often involve inadequate lighting conditions; they particularly affect individuals with cataracts or other disease conditions. The condition is relieved somewhat by using incandescent rather than fluorescent lighting, wearing a visor, wearing special antiglare lenses, and using a matte-black cardboard typoscope for reading words on a glaring white paper.
