Mineral Glass is created from natural elements like sand and soda ash. It’s endlessly recyclable and harmless to humans and animals alike. Its high resistance to scratching and lack of distortion make it the world’s best lens material. It really does have to be Mineral Glass.
100% UVA/UVB PROTECTION
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 aging while maintaining true color and depth perception.
6 BASE LENS CURVE
Lens 'Base Curve' is a measure of the front curvature of the lens. The higher the number, the greater the curve. 6 base lenses are generally flatter across the front. 8 base lenses have a greater curve for a more 'wrapped' look.
Sizing: 56.8 - 15.5 - 135 (mm). For more information on sizing visit our Frame Dimension Guide.
