DuraVision® BlueProtect – the solution for indoor activities
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*:
|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’).
