HARD COAT AND HARD MULTI COAT LENSES

SCRATCH-RESISTANCE AND ANTI-REFLECTIVE COATINGS

Vivo Optics’ extensive range of coatings can be applied to almost all types of lenses.

UNCOATED (UC)

This refers to a plain lens with no coatings.

UV400 TREATED LENSES

This lens is treated with a chemical dye that blocks out ultraviolet (UV rays of up to 400 nm wavelength, thus providing UV protection.

HARD COAT (HC)

This protective coating makes the lens surface scratch-resistant by increasing the abrasion resistance of the lens material. It is best to have all plastic lenses hard-coated.

HARD MULTI-COAT (HMC)
This combines 2 types of coating:

1. Hard Coat that is sturdy and scratch-resistant
2. Anti-reflection Coat (AR) that reduces surface reflection
