Ultra violet rays are lights not visible by man with wavelength between 280nm and 400 nm. This radiation reaches the earth at different intensities according to the season, geographical position and altitude. UV has a beneficial role for human health associated with bone strengthening by the metabolization of vitamin D and as a regulator of the immune system. However, it is noted that it promotes irreversible epithelial damage as mutations. The standardization and quality of eyeglass lenses are certified by INMETRO based on international standards. This study discusses the durability of the treatment present in lenses, the efficiency and presence of a protective filter in the products available to the consumer today.
