LENSES

Nylon - Nylon (polyamide) lenses are produced through injection moulding and are directly coloured in the moulding mass. They undergo anti-scratch treatment, are shock resistant and offer excellent protection from UV rays.

CR 39 - CR 39 is also called hard resin or organic glass, a valid and highly efficient alternative to glass. CR39 offers good UV protection, have high impact resistance, and in comparison with other plastics CR 39 is much more non-scratch even without non-scratch surface treatment and they are lightweight and assure minimum chromatic aberration.

LENS CATEGORIES

FRAMES

Acetate - Cellulose acetate is one of the most versatile of all plastic frame materials and the most commonly used. It is a very adaptable material that can have a wide range of possible colour combinations, they are hypoallergenic and have high mechanical strength and chemical resistance.

Polyamide (nylon) - Safilo uses two kinds of polyamide (nylon) materials: TROGAMID and GRILAMID. Both these plastic materials have a high performance and do not cause any type of allergies.

Grilamid - grilamid is a thermoplastic material for injection moulding. Research in the field of plastics has recently led to the use of grilamid TR 90 LX, a grade of nylon that meets all the requirements needed for a material used for spectacle frames. Grilamid is extremely strong, very lightweight, is easy to heat and shape if needed. Another advantage of having grilamid frame is that they are resistant to perspirations, cosmetics and detergents.

Metal- Metal frames use special alloys such as nickel silver, Monel, copper/beryllium, bronze and special bronzes. Thanks to their specific characteristics, these alloys are particularly suited for the production of frames and frame components.
