摘要

The anti-glare spectacle lens is characterized by the fact that it has an upper region with strong attenuation of the light and a region below that with a lesser attenuation. The limit of the area (3) between the area (1) with the strong light attenuation and the area (2) with lesser light attenuation is essentially straight at least in the middle portion of the glass and is situated between 1 mm and 8 mm above the main viewing point D for video screen work. According to the invention the light attenuation achieved in the upper region is more than 30%.
