ZEISS FSV Single Vision DuraVision BlueProtect UV Index 1.56

Description

DuraVision® BlueProtect UV is a coating specifically developed for customers who spend a lot of their time indoors and are exposed to blue-violet light from LEDs as well as TV, computer or tablet screens. ZEISS’ blue light coatings for spectacle lenses block specific wavelengths of light, and can help to relieve the eyestrain perceived by the customers which is typically associated with blue light exposure.

What is blue light and how can blue light coatings help your customers?
Natural light, i.e., sunlight, contains many types of coloured light. One of the shades of light in the visible spectrum is blue light. It accounts for about one third of high-energy visible light (HEV). Blue light ranges from 390 to 500nm on the visible light spectrum, which penetrates the eyes easily, passing through the cornea and lens to the retina. Blue light filter solutions such as blue light lens coatings for spectacles are a suitable solution to this problem. By wearing appropriate lenses with a blue light coating, a reduced amount of blue-violet light can enter the eye. Scientific evidence has indicated there are benefits to blue light exposure, however potential associated risks have also been mentioned (referred to as the dualism of blue light).
