Computer vision syndrome (CVS) is a condition resulting from focusing the eyes on a computer or other display device for protracted, uninterrupted periods of time and the eye's muscles being unable to recover from the constant tension required to maintain focus on a close object.
Observations from persons experiencing chronic eye strain have shown that most people who claim to be getting enough sleep are actually not.
[4] A routinely recommended approach is to consciously blink the eyes every now and then (this helps replenish the tear film) and to look out the window to a distant object or to the sky—doing so provides rest to the ciliary muscles.
Office spaces with artificially dry air can worsen CVS syndromes, in which case, a desktop or a room humidifier can help the eyes keep a healthy moisture level.
A 2017 randomized controlled trial evaluated macular carotenoid supplements (lutein, zeaxanthin, and mesozeaxanthin) in people with high screen time usage.
A study sponsored by the lens industry has shown blue light-filtering lenses decrease specific aspects of light emissions.
The expansion of technology has led to more individuals utilizing computers and televisions which increase the overall exposure to blue light.
