NEW Blue Light Lens Coating
Zeiss has a new Blue-Violet Light Blocking lens that is not yellow! I haven't done extensive research on blue light but according to the DuraVision BlueProtect lens page on the Zeiss website, "Viewing digital devices at night can disrupt the brain's production of melatonin, causing sleep disturbances and a dysfunction of the natural circadian rhythm." Their website also states that "The American Macular Degeneration Foundation warns that retinal damage caused by blue light may lead to macular degeneration. Evidence suggests that long-term exposure to blue light may contribute to photochemical damage of the retina (known as 'blue light hazard')."
As an Optician selling blue light blocking lenses, the yellow tint that is on the market is a tough sell. The majority of the patients who are interested in the function of the lens opt out because of the color; However, with the new lens from Zeiss, lens color is no longer a reason to lose a sale.
Take a look at the coating, the top frame has the Zeiss DuraVision Platinum Anti Reflective coating and the bottom frame is using the Zeiss DuraVision BlueProtect, notable color difference, but much better than a yellow lens.
