All OTIS fixed-tint lenses block 100% of harmful UVA, UVB and HEV light to provide superior protection from solar damage causing intraocular melanoma and macular degeneration, as well as reducing eye fatigue and reducing the visible signs of ageing, while maintaing true color and depth perception.
Lens 'Base Curve' is a measure of the front curvature of the lens. The higher the number, the greater the curve. Sizing: 59 - 18 - 128 (mm). For sizing help see our Frame Dimension Guide.
