Polarized Glasses Attachment Sport Clip On Polarized glasses are sunglasses whose lenses are equipped with a special light filter. This mainly filters light reflections from water or metallic surfaces, which is emitted at a certain exit angle. (Depending on the angle of light, the effect of polarized lenses is strong or sometimes not at all.) The glasses are well suited for drivers and especially for anglers or sailors, as the eyes do not tire so quickly and you can stay focused longer. The polarized glasses attachments have a 100% UV protection factor of 400 With the attachment you have a lens opacity up to class 3 and therefore these glasses are well suited for very strong sunlight and still approved in the STVO.
