Scratch-Resistant 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.

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

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.

Handcrafted Quality – Each frame is carefully handcrafted and brought to life. This means every single frame is checked and finished to the highest standard.⁠⁠

Visottica Hinges – Your sunglasses’ hinges get folded thousands of times throughout their lifetime so it's critical they’re made to last. All OTIS frames use high-quality, Italian-designed Visottica hinges to keep things together, use after use after use.

Plastic-Free Packaging

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.
