Dior Acetate Frames are easy to adapt and lenses are easily inserted, Acetate frames come in a great variety of styles and are made of hypoallergenic material.
Dior CR39 Lenses
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.
CR39 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.
Advantages of
CR39 sunglass lenses:
- Offer good protection from UV radiation
- High impact resistance
- CR39 has a higher threshold against scratching than other plastics even without a non-scratch surface treatment
- Lightweight: thickness being equal, their weight is half the weight of glass lenses
- Minimum chromatic aberration.
Base lens curvature is the base curve or front curve of the lens measured in diopters (light bending capacity of a lens). Higher numbers mean increased curvature.
Dior Cottage 1 Sunglasses meet the Australian and New Zealand standard 1067:2003 category 2. Category 2 Sunglasses offer medium sunglare reduction and good UV protection.
