Lens Coatings

Coatings are applied to the surface of lenses to reduce reflection and glare, which enhances your vision. They also make your lenses last longer and are scratch-resistant.

There are two coatings options to choose from:

1. Diamond

Caledonian Optical's flagship coating, designed to give the wearer outstanding levels of glare protection. Combined with high quality Antistatic, Super-Hydrophobic and Oleophobic layers, the lenses are significantly protected against the build-up of contaminants such as dust, grime and water from landing and staying on the lens. Thus, giving exceptional clarity throughout the day.

And to protect the lens further, extra hardcoat layers are built into the process to provide an outstanding resistance to scratches.

Our iC Diamond coating is regularly tested to ensure consistency throughout. It goes through the following procedures: Saltwater Boiling test, Steel Wool Abrasion test, Eraser Abrasion test, Humidity test, Dry Heat Crack test & Hydrophobic properties test.

2. Intero

Our Intero coating solves the reflectance issue by absorbing UV rays hitting the back of the lens. Thus providing the best all round UV protection.

All high index lenses we provide have 100% UV filter imbedded in the material, which prevents UV rays passing through the front of the lens. All standard AR coatings can reflect UV rays from the back surface of lens into the eyes. This can be as much as 50% of exposure. Our Intero coating solves the reflectance issue by absorbing UV rays hitting the back of the lens. Thus providing the best all round UV protection.
