*CAT - Is an abbreviation for the English word "Category". The designations CAT 1 - 4 indicate the tint level of sunglasses. However, the tint level has nothing to do with the UV protection of sunglasses; the number merely indicates how strong the glare protection and the tint (lighter or darker) of the sunglasses is.
