Companies selling glasses that filter out the blue light from computers claim that overexposure to blue light causes disruption of the sleep-wake cycle, dry eyes and macular degeneration. Exposure to ultraviolet light from the sun is associated with cataract formation and other eye diseases. However, no measurable UVA or UVB radiation is emitted from computer monitors, tablets or smartphones. Special glasses are therefore not necessary.
Some simple measures are recommended to reduce eyestrain. The simplest is to look away from the computer every 20 minutes and to gaze far away (eg out of a window or down a long corridor). This will relieve the prolonged focusing. Further, when the eyes feel dry use artificial tears to moisten them.
