Our Shaka unisex sunglasses feature a retro wayfarer style with a large TR90 frame and TAC polarized lenses.
TR90 is a super-polymer compound that is extremely lightweight, incredibly sturdy, but very flexible.
TAC is the acronym for Tri Acetate Cellulose used in lens construction. These lenses are comprised of a scratch resistant plastic and block 99% of all UV rays up to 400 nanometers.
Frame color: outside frame matte brown and green camo – inside frame matte blue
Lens color: amber
Amber lenses brighten vision on cloudy days and in low light situations by blocking blue light and reducing glare. Amber lenses also increase contrast and visual acuity, which is most effective against green and blue backgrounds. They are a good choice for fishing in brackish water, golfing, cycling, driving, and water sports.
