Our Tornado Bifocal sunglasses are comprised of a large frame with small, vented rubber nose pads. It sports a decorative metal accent at the hinges featuring TR90 frames and polycarbonate polarized lenses. Available strengths are: +1.50, +2.00, and +2.50. Your order arrives packaged in a microfiber pouch which doubles as a cleaning cloth.
TR90 is a super-polymer compound that is extremely lightweight, incredibly sturdy, but very flexible.
Polycarbonate (PC) lenses are lighter than glass, scratch resistant, shatter resistant, and offer improved visual clarity over the TAC lenses.
Matte Black frames are a popular choice with a muted black look that adds a touch of class.
Smoke lenses keep colors neutral while the medium to dark gray, smoke tint blocks the sunlight. This results in less light reaching the eyes and makes bright sunlight easy on the eyes.
