Since the amount of blue light from the devices used at work, school and home is less than that of natural sunlight, and eyestrain hasn't been found to be related to blue light, what can be done to prevent it? However, in reviewing the research, no significant improvement in vision performance or sleep quality has been found from using blue-blocking lenses. Studies have been conducted with adults on the benefits of blue-blocking lenses - whether these lenses alleviated eyestrain and discomfort when using digital devices and if sleep quality improved when the lenses were used in the evening. Some digital devices now offer blue light-filtering settings that reduce the transmission of short wavelengths of light. These products decrease the transmission of ultraviolet light involving wavelengths between 440 and 500 nanometers. Since 2008, research into blue-blocking or filtering products, such as blue-blocking glasses, has increased. Up to 69% of computer users report eyestrain, also known as computer vision syndrome.

In animal studies, prolonged exposure to natural blue light has been shown to damage the retina. Concerns about blue lightĮxposing the retina to shorter light wavelengths is the basis of "blue-light hazard" and contributes to phototoxicity or sensitivity to light. Blue-light exposure can affect the retina - the layer of cells lining the back wall inside the eye that sense light and send signals to the brain so you can see. When the sun is shining, this is natural white light.īlue light has a shorter wavelength with higher energy: 400–500 nanometers. The others are red, orange, yellow, green, indigo and violet.
