Four Types of Glare: 2. Disabling Glare

By editor

Glare is defined as a visual condition in which the observer feels either discomfort and/or exhibits a lower performance in visual tests (e.g. visual acuity or contrast sensitivity). This is produced by a relatively bright source of light--called the glare source--within the visual field. A given bright light may or may not produce glare depending upon the location and intensity of the light source, the background luminance, the state of adaptation of the eye or the clarity of the media of the eye. Although the term "glare" is used many times in a general sense, there are actually four different types of glare. The second type of glare is Disabling Glare. Disabling Glare is caused by light too bright for the eye and reduces/blocks vision due to retinal veiling (this is like a veil or haze over the retina). The solution for this type of glare is fixed tint or photochromic lenses.
