LENSES

Nylon (Polyamide) lenses are produced through injection moulding and they are directly coloured in the moulding mass or in a second moment with uniform or shadowed colours.

Here are the advantages of this material:

• It has class 1 optical quality

• It offers excellent protection against UV radiations

• It undergoes an anti-scratch treatment 

• It is shock-resistant

•  It offers better resistance to cracking under stress.

CR 39: It is also called hard resin or organic glass. CR 39 has been used in the optical field since the Fifties and represents a valid alternative to glass to obtain good quality sunglass lenses. CR 39 is the name of the initial liquid compound that is catalysed with peroxide and injected in glass moulds. After a twenty-hour thermal cycle lenses can be extracted: they will be graduated or afocal depending on the internal curvature of the moulds.

Why using CR 39 lenses?

•  They offer good protection from UV radiation.

• They have a high impact resistance in comparison with other plastics CR 39 is much more non-scratch even without non-scratch surface treatment.

•  They are lightweight: thickness being equal, their weight is half the weight of glass lenses.

•  They assure minimum chromatic aberration.

FRAMES

Acetate: Cellulose acetate is one of the most versatile of all plastic frame materials and the most commonly used. It is obtained from cotton flock s and wood pulp, and it can have a great variety of colours, with either a single colour or multiple colours. This material is very adaptable, has a wide range of colours and great for a variety of shapes and surface finish. It is durable and hypoallergenic.

Injected Plastic: This type of frame is produced by injecting the liquid form of plastic into a very precise mould. Injected frames allow for a more contoured fit on the face and bridge. They are thinner and lighter to wear. This process allows the ability to replicate intricate patterns.

Monel Metal & Titanium: This is the most widely used metal in the high-quality manufacturing of sunglasses. Other metals can include Titanium, Stainless Steel and Flexon. Monel metal is a mixture of any of a broad range of metals such as nickel, copper and iron. This metal keeps strength when shaped and is corrosion and stress-resistant.
