Four Types of Glare: 4. Distracting Glare
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 fourth type of glare is Distracting Glare. Distracting Glare is primarily an annoyance created by light reflecting off the surface of a lens, or internally reflecting within a spectacle lens. This kind of glare may cause eye fatigue, annoyance and distraction. It is also experienced at night around headlights or street lights. An anti-reflective treatment is the solution for this problem.For further information or to book an appointment please call any of our three Rochester, NY Cornerstone Eye Associates locations in Gates (585-328-0153), Brighton (585-244-2200) or Irondeqouit (585-266-7880).
