Revo's Serilium+ polarized lenses layer precision-applied coatings to filter UV, HEV blue light, and infrared while boosting contrast and color. This pair features Terra tinted lenses, chosen to complement the frame and deliver the visual contrast the wearer notices first. Originally engineered for NASA, Revo's Light Management System uses up to six layers of coatings to deliver unmatched optical clarity. Polarization eliminates reflected glare; anti-reflective treatment sharpens the rear-surface experience.
