MINERAL GLASS

Mineral Glass is created from natural elements like sand and soda ash. It's endlessly recyclable and harmless to humans and animals alike. It's high resistance to scratching and lack of distortion make it the world's best lens material. It really does have to be Mineral Glass.

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. 50.5 - 21 - 147 (mm). 

HANDMADE ACETATE FRAMES

Made with premium quality acetate (originating from renewable resources wood pulp & cotton fibre), the ideal material for making durable eyewear. Its hue is embedded within the product rather than sprayed onto the surface, retaining colour brightness and preventing peeling & fading. OTIS handmade frames have stainless steel wires injected into the temples for adjustability - a task best performed by an Eye Care Professional.

VISSOTTICA HINGES WITH STAINLESS STEEL SCREWS

OTIS frames are produced with high quality 3, 5 and 7 barrel hinges. These premium grade Vissottica brand hinges are extremely durable and boast 100% corrosion resistance.
