Background
Glare is a poor lighting phenomenon, and occurs when the brightness of a light source is extremely high or the difference between the brightness of the background and the brightness of the center of the field of view is large.
Glare is a great injury to the eyes. Due to the stimulation of high bright light, the pupil is excessively contracted, the ciliary body is spastic, the eyes are continuously adjusted and adapted, and the visual fatigue and the ametropia are easily caused, especially to outdoor workers, driving groups and office groups. The retina is stimulated by high light, so that the retina in an originally appropriate state is damaged, the visual function is affected, and the vision is degraded. Glare not only causes visual discomfort, but also intense glare can impair vision and even cause blindness.
Besides causing damage to eyes, glare may also cause mild aversion and headache to the body, and in severe cases, may also affect driving safety, especially during night driving. The glare caused by the lamp light at night or the street lamp or the lamp light reflected by the ground or the back forms a sharp contrast with the dark night, the human eyes need adaptive time in the environment change with high brightness difference, especially when the brightness changes into the dark, the excessive strong light enters the human eyes to 'bleach' (the purple blue hydroformylation in the cone cells is too fast) the retina, the contrast of the scene to be watched is reduced, the dark adaptation needs longer time, when the brightness changes sharply, the human eyes can easily feel 'blind', the road condition can not be distinguished instantly, accidents can easily occur, and traffic accidents can occur. Meanwhile, the strong light can also cause accelerated retina glycolysis reaction, and symptoms of eye fatigue, such as eye ache, scalp tension and other discomfort, appear after the triple symptom of eye movement is strengthened.
