ZEISS DuraVision BlueProtect UV reflects parts of the blue-violet light emitted from LEDs as well as TV, computer or tablet screens, preventing it from entering the eye.
This ZEISS coating reduces the transmission in the spectrum of 380–455 nm (blue light hazard) while keeping the high transmission level above 460 nm.
However, we must always enjoy comfortable vision.
There is a body of evidence to suggest that blue light in the spectrum between 400 and 520 nm with a maximum at 460 nm is important for the proper regulation of melatonin in the body, which influences circadian rhythms (day-night rhythm) and general well-being.
On the other hand, there is a body of evidence to suggest that long-term exposure to blue-violet light below 460 nm, with a maximum at 440 nm, may contribute to photochemical damage of the retina, increasing the risk of macular degeneration over time (known as the ‘blue light hazard’).
Exposure to harmful blue-violet light varies greatly indoors and outdoors. It is important to have adequate blocking of the blue-violet light depending on its intensity.

✓ Address consumers’ health concerns with ZEISS blue-violet light blocking solutions.
✓ Offer a comprehensive portfolio that takes into account the different intensity levels of harmful blue-violet light in indoor and outdoor activities.
ZEISS offers a comprehensive blue-violet light blocking portfolio that meets different consumer requirements for indoor and outdoor activities, filtering different amounts of blue-violet light depending on the activity.
Sunglass lenses or self-tinting lenses with ZEISS PhotoFusion feature 100% UV protection when you’re outdoors in the sun. An optional enhancement for indoors: ZEISS DuraVision BlueProtect UV. This lens coating also filters out blue light with non-tinted lenses.
Tinted or self-tinting lenses partially absorb blue-violet light
ZEISS DuraVision® BlueProtect UV partially reflects blue-violet light
* ZEISS exclusively developed the BPI to simplify the recommendation of an adequate blue-blocking solution depending on the wearer’s activities.
