Eye Protect System™

Making eye protection accessible to everyone

We have made it our mission to help our customers provide protection against harmful light. Eye Protect System, an embedded lens protection achieves just that.

Three embedded patient benefits

Harmful light* protection in an aesthetically clear lens

Eye Protect System is the first embedded protection against harmful light in an aesthetically clear lens using a unique lihgt absorption process resulting in three benefits:

  • UVA & UVB are efficiently absorbed by the lens**
  • Up to three times more protective against blue-violet light than standard prescription lenses*** 
  • Enhanced lens aesthetics without altering colour perception
Harmful Light Protection

Technology behind Eye Protect System

Blue Light Filtering Logo
Smart Blue Filter™

The Smart Blue Filter innovation was designed to distinguish harmful blue-violet light from essential blue-turquoise light. Absorbing the former and transmitting the latter. By using specific absorbers for blue-violet light embedded inside the lens such that blue-violet light reaching both the front and the back-surface of the lens is filtered.

Eye Protect System Logo
Aesthetic clarity

The absorber filtering partially blue-violet light attributes a natural yellow-orange colour to the lens which may not be cosmetically appealing for a clear day to day lens. To counteract this, two neutralising molecules were added to the Smart Blue Filter. Specific complementary colour absorbers neutralise yellow residual colour.

Enhanced protection

Combined with Crizal UV

This new embedded innovation offers the key advantage of being compatible with all Crizal® coatings. Building on the existing Crizal UV coating, Essilor combined the embedded Smart Blue Filte feature with E-SPF®, offering an aesthetically clear lens with both UV and blue-violet protection called Eye Protect System.

As such, the lens filters on average 20% of the blue-violet light between 400-455 nm, combined with UV protection [Figure 14]. Its blue light photoprotective effect on retinal cells (RPE) in vitro is equivalent to that offered by Crizal® Prevencia® coating giving a 25% (±5%*) decrease in retinal cell death.

* Harmful light = UV and blue-violet light
** For Eye Protect SystemTM lenses with Crizal Forte® UV, 25% decrease in light-induced retinal cell death versus no filter. For standard lenses: Orma 1.5 or Airwear 1.59 with Crizal Forte® UV, about 7% decrease (mathematically modeled).The E-SPF® index depends on the lens material itself and the coating. E-SPF® is a global index rating the overall UV protection of a lens. E-SPF® was developed by Essilor International and endorsed by 3rd party experts. Lens performance only. The E-SPF® index excludes direct eye exposure that depends on external factors (wearer’s morphology, frame shape, position of wear). Orma 1.5 does not absorb 100% UV light.​
*** Based on In Vitro photoprotection tests on retinal cells. Smart Blue Filter™ lens feature provides a minimum level of efficacy, decreasing light-induced retinal cell death versus no filter: 25% (+/-5%). It depends on the lens material and the coating and can be evaluated by in vitro tests on RPE (Retinal Pigment Epithelium) cells or by mathematical modeling.
