Lens Treatments

man wearing glasses in the sunA lens treatment is a special additive that either bonds with the lens, or is built into the lens during the lens manufacturing process. Lens treatments are available as individual additions to lenses, and are also commonly bundled into single lens products for convenience and maximum benefit to your eyes.





Eye Health Protection

UV Protection

The Broad spectrum technologyTMeliminates UV rays reflected into the eye from the back side of the lens, without any compromise on lens transparency, for long-term eye health.

The Eye-Sun Protection Factor (E-SPFTM)** is a new index developed by Essilor, endorsed by an independant 3rd party, certifying the global UV protection your lenses are providing to your eyes and the skin around your eyes. As with the index used the rate skincare and sunscreen products efficiency, the higher the value the better the level of protection. All lenses are not equal in terms of UV protection: Crizal offer the best protection on the market.*


Blue-Violet Light Protection

– It provides optimal clarity of vision and durable transparency by offering the most complete protection against the ennemies of clear vision (glare, scratches, smudges, dust, water).

Glare Reduction



prevent light interference on the surface of the lens, thus eliminating glare.

Scratch Resistance

 introduction of an extra thin layer called the SR Booster™(Scratch Resistance) optimizes interaction among the different layers, and boosts or strengthens the whole stack. It considerably increases the scratch resistance of the lens.

Smudge Resistance : Easy to clean

 HSD™ Process (High Surface Density Process) is a technology that optimizes smudge resistance by increasing the density of hydrophobic and oleophobic molecules on the surface of the lens. Consequently, water and smudges are better repelled and the lens is easier to clean. and smudges are better repelled  and the lens is easier to clean.

Dust Repellence: Less light diffusion for optimal Vision



Drawing inspiration from space and fibre optics technologies, Essilor’s R&D  department developed i-Technology™. This exclusive innovation creates an anti-  static layer which repels dust and prevents light diffusion for optimal vision.



Water Repellence: Water slide off without trace

 integration of a layer of hydrophobic molecules on the surface of a Crizal lens minimizes water adherence. Slide-FX™technology developed by Essilor shows that calibrated water drops placed on a Crizal lens will roll into tiny balls and simply slide off without a trace when the lens is tilted.

 Fog Repellence


A top layer with anti-fog properties, activated by the Optifog™Activator™ once a week or more often as needed, offers you long-term fog-free vision, with no distortion or loss of contrast.
