    DuraVision® BlueProtect - the solution for indoor activities

    DuraVision BlueProtect

    ZEISS DuraVision® BlueProtect reflects parts of the blue-violet light emitted by these sources, preventing light from entering the eye.


    This ZEISS coating reduces the transmission in the spectrum of 380–455 nm (blue light hazard) to a BPI 15 while keeping the high transmission level above 460 nm.

    Our exposure to blue-violet light may not always be the same.

    However, we must always enjoy comfortable vision.

    Blue-violet light is everywhere, although its intensity varies greatly.

    While a typical LCD computer monitor produces a brightness of 250 cd/m2, a clear blue sky at midday is 32 times as bright. Direct sunlight can be thousands of times as bright.

    The two sides of blue-violet light*:

    The two sides of blue-violet light

    Filtering blue-violet light at 440 nm and below should have minor impact on our circadian rhythm (the body’s day-night rhythm), while providing beneficial protection from potential phototoxicity.

    Pro Contra
    Regulates circadian rhythm (day-night rhythm)
    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.
    Increases risk of macular degeneration
    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’).

    Requirements in terms of blue-violet light blocking.
    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.

    The ZEISS Blue-Violet Light Blocking Portfolio -

    made to fit any situation of blue-violet light exposure.

    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.

    ZEISS Polarised Lenses and PhotoFusion by ZEISS are tinted and self-tinting lenses that block different intensities of blue-violet light as well as offering 100% UV protection. A new addition has now been made to the portfolio: DuraVision® BlueProtect by ZEISS, a new coating to partially block blue-violet light; ideal for indoor activities.

    The ZEISS BlueProtect Index (BPI) facilitates the selection of the correct blue-light-blocker solution depending on the most common activities of the wearer, taking 100 as the maximum blocking provided by Skylet® tints.
