The protection level of sunglass lenses is indicated by a category number. Category 1 lenses are suitable for cloudy and dim conditions where contrast-enhancing lenses are needed. Category 2 lenses provide light sun protection, and category 3 lenses are a great choice for summer use. Category 4 lenses are so dark that they are not recommended for driving. Cat 4 lenses are ideal for activities like boating and spring snow conditions, where light comes both directly from the sun and reflected off snow or water surfaces.
Lenses always have a specific base color. Gray is a neutral choice. Brown, reddish, and purple enhance color contrast. Yellow and orange are effective in low-light conditions. The mirror coating on the lens is different from the color visible on the inside of the lens. The sole purpose of the mirror coating is to reduce glare, and its color does not affect the lens’s other functional properties — so simply choose the color you like best, as long as the other features meet your needs!
Polarized lenses are particularly effective near water and for activities like fishing. They reduce glare from the water’s surface and allow visibility beneath the surface – a useful feature for fishing. However, polarization can make viewing certain screens more difficult.
Photochromic lenses darken automatically according to the conditions: the brighter the light, the darker the lenses become.
