Why to Choose CR-39 Optical Lenses?
The UV rays in sunlight can be harmful to the eyes.
Lenses that block 100% UVA and UVB help to ward off the damaging effects of UV radiation.
Photochromic lenses and most quality sunglasses offer UV protection.
Why to Choose CR-39 Optical Lenses?
Crystal Vision (CR) are top quality lenses made by one of the world’s largest lens company.
CR-39, or allyl diglycol carbonate (ADC), is a plastic polymer commonly used in the manufacture of eyeglass lenses.
The abbreviation stands for “Columbia Resin #39”, which was the 39th formula of a thermosetting plastic developed by the Columbia Resins project in 1940.
Owned by PPG, this material is revolutionising lens making.
Half as heavy as glass, far less likely to shatter, and optical quality nearly as good as glass.
CR-39 is heated and poured into optical quality glass moulds – adapting the qualities of glass very closely.
Scratch-Resistance
Scratches on lenses are distracting,
unsightly and in certain conditions even potentially dangerous.
They can also interfere with the desired performance of your lenses.
Scratch-resistant treatments toughen up the lenses making them more durable.
Anti-reflective Treatments(AR)
For fashion, comfort and clarity, anti-reflective treatments are the way to go.
They make the lens nearly invisible, and help cut glare from headlights, computer screens and harsh lighting.
AR can enhance the performance and appearance of just about any lenses!
