The RAV 7™ series Optical Monomers produce high quality low index (1.50) ophthalmic lenses.
They are characterized by a high scratch and weather resistance, are tintable and have optical performance close to mineral glass.
Apart from ophthalmics, RAV 7™ extends its use to applications in the marine environment and use in welding masks, as well as photographic filters.
