Otis The Insider 90-1701P Matte Black / Grey Polarised Lenses

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 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. 4 and 6 base lenses are generally flatter across the front. 8 base lenses have a greater curve for a more 'wrapped' look.

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.

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.
