What makes OTIS so unique?

Environmentally friendly. Scratch resistant. Optically correct.

Every OTIS lens is made from non-toxic natural materials like sand and soda ash. At the end of their long life, they’re also endlessly recyclable. 

They are thermally hardened, enhancing their already natural scratch resistance and durability. 

They’re also ground, polished and precision tested for clarity control, making them 100% optically correct. 

It’s hard to think of a better lens material than mineral glass. Just check out how they are made in the clip below...
