Blue Light – is it Bad for Your Eyes?

Natural light contains many types of coloured light- one shade in the visible spectrum is Blue Light. It easily penetrates the eye, passing through the cornea and lens ( the focusing system) to the retina at the back of the eye. The retina is the layer of cells lining the back wall inside the eye. This layer senses light and sends signals to the brain so you can see.

Exposure to Blue Light during daytime helps the body to maintain a healthy circadian rhythm which is the body’s natural sleep-wake cycle.

Exposure to concentrated Blue Light over long periods (eg screen use) can lead to possible damage to retinal cells.

Zeiss has developed a Blue Protect UV coating specifically for people who spend a lot of time exposed to Blue-Violet light from LEDs, TV, computers or tablet screens.

Zeiss Blue Light coatings block specific wavelengths of light and can help to relieve the eyestrain typically associated with Blue Light exposure.
