Layering cutting-edge coatings on lenses can help them go the extra mile, as these added layers can maximise durability and clarity, with improved wearability and protection. Vivo Optics’ extensive range of coatings can be applied to almost all types of lenses.

GENERAL COATING GUIDE

coating-1

UNCOATED (UC)

This refers to a plain lens with no coatings.

coating-2

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.

coating-3

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.

coating-4

Colour Hard Coat Tintable (HCT)

This special type of hard coating can be dyed (tinted) with the colour you want. It is generally softer than normal coatings applied to plastic lenses.

coating-5

Hard Multi-Coat (HMC)

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