The manufacturer says 100% UVA and UVB protection. Are you suggesting that these claims need to be verified somehow?


From the ANSI website (www.ansi.org):

"One safety issue that consumers do tend to be aware of is protection from ultraviolet radiation (UVA and UVB). Mr. Wood notes that the amount of UVA and UVB protection depends upon how a consumer intends to use the sunglasses, the two types of use classified as Normal Use (from home to the car to the office) or High and Prolonged Exposure (at the beach, fishing, skiing). Lenses are also classified for intended function as special, dark, general purpose or cosmetic tint. The combination of the intended function and the type of use gives a total of eight UV transmittance specifications."
