What Causes Glare?
Glare may be regarded as light in the wrong place. The more concentrated the light, the more disturbing the effect. In essence, glare is the light brilliance surrounding the object of regard. While it is good to have an object surrounded by an ambient area of a lower illumination, if the object illumination is lower than the surroundings, the light constitutes glare. Glare is one of the most potent causes of eye strain. Glare has to be always contended with on ice and snow where the reflection of light is high, necessitating appropriate glare glasses. During reading, glare is the reflection of light of a shiny page, or even of shiny objects kept on the table. The reading surface of the table should be of a dull matt texture and the book appropriately tilted to prevent the reflection of light from the book or the table into the eyes.
