These lenses are not coated.
UV400 TREATED LENSES
These lenses are treated with a chemical dye to block out harmful ultra-violet (UV) rays.
HARD COAT (HC)
These lenses are coated with a protective coating that increases the abrasion resistance of the lens material. It is strongly recommended that all plastic lenses be hard-coated.
COLOUR HARD COAT TINTABLE (HCT)
Special type of hard coating that can be tinted with colour dyes. These coatings are generally slightly softer than normal coatings applied to plastic lenses.
HARD MULTI-COAT (HMC)
The Hard Multi-Coat is an integration of 2 types of coating
- Hard Coat - to increase the abrasion resistance of the lens
- Anti-Reflection Coat (AR) - to increase the transmittance of the lens and reduce surface reflections
- Hydrophobic Top Coat - repels water to keep the lens surface clean
