Our Bombora sunglasses feature a medium TR90 frame and TAC polarized lenses. Along with spring hinges, the rubber nose pads and rubber non-slip temple grips create a snug fit.
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 is matte black – inside frame is frost lime green and frost blue
Lens color: smoke mirror blue
Blue Mirrored lenses have a reflective blue coating made up of thin layers of titanium and silicon oxides. They can eliminate up to 97% of infrared rays, in particular in the blue spectrum to enhance color.
