Category 4 Sunglasses

Category 4 sunglasses have dark lenses for use in environments where high glare or intense sunlight is experienced. Category 4 lenses let in 8% (or less) of light – this makes them suitable for activities like skiing, mountain climbing, high altitude hiking and desert trekking. Included are photochromic models with light adjusting lenses that darken to Category 4. Category 4 lenses are also suitable for eyes that are sensitive to sunlight.
