Blue Light: the Good and the Bad

How much blue light do we need?

And how and when should we be protecting ourselves against it?

Can blue light blocking glasses or lenses help?

A debate is raging over the beneficial and damaging effects of blue light. On the one hand, blue light can be a helpful tool in combating seasonal depression and insomnia. On the other hand, blue light can permanently damage the human eye. So what's the deal with blue light? 

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’).

Some people find that light sources with a high proportion of blue light can make them feel more restless at night.


When we find ourselves in a dark room or outside at dusk or at night-time, our eyes switch to a different mode of vision. In low_light the human eye shifts from green sensitivity to the high-energy blue spectrum. That means we perceive blue light more intensely, which can give the sensation of increased glare.


This effect will be familiar to drivers who have been blinded by the glaring headlights of oncoming vehicles, especially those with modern xenon or LED headlights. Eyeglass lenses with a blue light filter can create more comfortable vision in these situations.

EXCLUSIVE TECHNOLOGY! UV protection from all sides.

To offer patients true protection, ZEISS has developed an additional anti-reflective layer on the back of the lens, reducing the indirect light reflected into the eye.

This extra layer complements the protection offered by ZEISS UVProtect Technology in all clear plastic lenses, which blocks direct UV rays from the front.

More than 90% of UV radiation comes directly from the front. However, a small part approaches the eye indirectly from the sides and back. As some UV rays may be reflected onto the eye by the back surface of the lens, ZEISS anti-reflective coatings are designed to have low reflectance in the UV spectral range.

Back surface UV protection is now integrated as a standard feature into all premium ZEISS DuraVision coatings and mirrors.
