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.
ECO ACETATE FRAMES
Our Eco-Acetate frame is made from renewable resources widely present in nature.

4 BASE LENS CURVE
Lens 'Base Curve' is a measure of the front curvature of the lens. The higher the number, the greater the curve. 4 and 6 base lenses are generally flatter across the front. 8 base lenses have a greater curve for a more 'wrapped' look.
Frame Sizing: 48.5 - 23.5 - 145 (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.

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.
