Lens Excellence

We only make premium eyewear from naturally sourced, distortion-free, scratch resistant mineral glass lenses.

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 optical clarity, high resistance to scratch and lack of distortion make it the world's best lens material.

A hybrid glass half the weight and twice the strength of standard crown glass, delivering unparalleled clarity - making it the perfect lens material. 


Precision-ground mineral glass creates the ultimate distortion-free vision and is the most stable lens material in the world.

Scratch resistant

Mineral glass is recognized as industry-leading and the most scratch-resistant lens material available on the planet. 

Permanent Tinting

Mineral glass is created in permanent lens tints and provides the most stable colour contrast of any lens material. OTIS lenses can never warp, peel or fade over time. 

Thermal Hardening

A process by which the natural toughness of mineral glass is even further enhanced to increase durability. 


OTIS's proprietary Light Improvement Technology Lens provides the ultimate polarized color enhancement, anti-reflective and hydrophobic properties in scratch-resistant and distortion-free mineral glass.
