About the Coating
_________________________________________________________________________________________________________________________________________________
Hard coating make the uncoated lenses are easily subjected and exposed to scratches.
AR coating means hard&multi-coated,protect the lens effectively from reflection,enhance functional and charity of your vision.
Super hydrophobic coating make the lens waterproof,antistatic,anti slip and oil resistance.
Different coating with different performance, we have Uncoated(UC), hard coating(HC), AR(HMC+EMI), Blue Cut and Mirror coating and Tintied different color with sunglasses.
Anti-Reflective
- Eliminate reflections, Increase the transmission!
- Decreases unwanted glare, eliminating ghost image.
- Makes the lenses appear somewhat invisible.
Anti-Smudge
- High contact angle, repel oil and water, make lenses more stain-resistant.
- Super-cleanable.
Anti-Static Electricity/Anti-Radiation
- Help relieving digital eye strain.
- Stay Clean, repels dust articles.
