Boss 1752/SFew things can elevate a look and put you in a good mood like these BOSS sunglasses for men can. Its impossible not to notice the exquisite structure in two materials. The eco acetate insert along the top of the frames adds intensity. The finish is impeccable, even on the versions with a visible metal core on the inside. The versions with mirrored lenses ensure optimized vision. This style can be fitted with prescription sun lenses.
