ZEISS DuraVision BlueProtect offers protection from the harmful blue light from LED lights, digital devices, TV screens, and computers.
ZEISS DuraVision BlueProtect strongly filters blue light shorter than 440nm. This range is of particular concern to eye care professionals. Reducing the eye’s exposure to this type of blue light helps prevent retinal cell damage and phototoxicity.
ZEISS DuraVision BlueProtect reflects parts of the blue-violet light coming from those sources, hindering the light 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.
The two sides of blue-violet light*:
Blue light regulates the circadian rhythm to ensure alertness in daytime and restful sleep at night. Too much blue light from artificial lights at night can interfere with sleep. ZEISS DuraVision BlueProtect filters the undesirable wavelengths emitted from artificial lights between 440nm and 465nm, while allowing the beneficial blue light through.
