Standard Lenses (Non-Polarised)
OTIS standard lenses are all made from mineral glass that is scratch-resistant, environmentally friendly and distortion free. They have a fixed tinting that won’t peel or fade over time and block 100% of harmful UVA, UVB and HEV light, providing superior protection from solar damage, while maintaining true colour and depth perception.
Mineral Glass Lenses
OTIS mineral glass lenses are naturally scratch resistant, optically correct and more sustainable than the plastic alternatives that go in most other eyewear. This makes them easily the best sunglass lenses on the planet.
All of our frames are made with high quality Italian designed Visottica hinges. These premium grade Vissottica brand hinges are extremely durable and boast 100% corrosion resistance.
TR90 Grilamid Frames
High performance and low weight ratio. TR90’s high-performance property profile and processability makes it an ideal optical engineering plastic. The transparency, rigidity and impact strength of Grilamid compare favourably to other transparent polymers like polycarbonate. It is the lightest engineering plastic in existence, maximising wearer comfort.
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 colour and depth perception.
Lens Base 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.
