Eye Protect System™


ExamVision, the first loupe with blue light protection in the oculars that does
not change colour perception.




Discover Eye Protect System™ from Essilor, a revolution in protection against harmful UV and
Blue-Violet light *.

Protect yourself - High quality work depends on healthy eyes
Your eyesight is one of your most valuable assets. Working in a bright, high-exposure LED environment means your eyes are vulnerable to harmful UV and Blue-Violet light. Over time harmful light is one contributing factor of eye diseases like cataracts or age-related macular degeneration (AMD **) .


One or more of these factors can put you at risk:


  • Long working hours in high exposure LED environment
  • Being over 45 years of age
  • Genetic disposition to AMD
  • Early signs of AMD

Unique protection embedded in the oculars
Essilor has found that Eye Protect System™ lenses are up to three times more protective against harmful Blue-Violet light than standard prescription lenses, based on in vitro photoprotection tests on retinal cells ***. The Eye Protect System™ lenses with the UV coating Crizal Forte® decreases light-induced retinal cell death with 25%. Eye Protect System™ is a combination of both E-SPF index & Smart Blue Filter feature.

The Eye Protect System™ is embedded in the lens, not an anti-reflective coating.

The Blue-Violet light in the 400-455nm band is the most harmful light in the Blue-Violet light spectrum.


The unique Eye Protect System™ contains light absorbing molecules able to target and partially filter the most harmful Blue-Violent light wavelengths while letting through beneficial blue turquoise light.

Protect your eyes from harmful blue light, without changing colour perception
There is no residual yellow tint and no blue reflections in the Eye Protest System™ lenses. Specific complementary colour absorbers enchance the colour perception, while maintaining aesthetic clarity. The Eye Protect System™ is available in your ExamVision loupe oculars.

NOTE: The Eye Protect System™ is NOT sufficient to protect your eyes when using a UV curing light.

Eye health relies on various factors (age, genetics, smoking, diet). Light is one of the modifiable risk factors on which an ophthalmic lens may act. UV is one contributing factor of cataracts. Blue-Violet light is one contributing factor of AMD (1).

Blue-Violet light photo-protective potency is measured or calculated. Measurements are done through in vitro photobiology experiments conducted by Essilor and a 3rd party. Photosensitized RPE (Retinal Pigment Epithelium) cells are exposed to Blue-Violet light, reproducing the physiological exposure to sunlight of the 40 year old eye. Calculation model is using an interpolation method of spectral data between 400 and 455nm. This model has been designed thanks to correlation between spectral measurements and in vitro test results on outer retina cells, with a dispersion of 5%. For Eye Protect System™ lenses with Crizal Forte® UV coating, 25% (+/-5%) decrease in light-induced retinal cell death versus no filter. For standard lenses: 1.5 or Poly material with Crizal Forte® UV coating, about 7% decrease.
