This report presents a survey of the available literature related to the present scenario of technical devices and methods to quantify visual fatigue and its long-term effects on the eye due to computer-related work, along with psychological and physiological aspects.

The introduction of computers during the 1970s gave rise to a lot of controversial debate. Controversies were wide-ranging, ranging from workplace ergonomics, lighting to health and work stress. The overuse of computers makes adults and children both susceptible to computer-related vision symptoms. Performing both important and enjoyable tasks without breaks until near exhaustion may increase eye focus problems and eye irritations. This calls for computer vision syndrome, which is a widely spreading but largely unknown epidemic among computer users. It is considered the top official health-related problem. In ancient times, human beings used to live in forests, and their primary occupation was hunting. Their visual need was to look at distance, but now the distance-dominated world has suddenly changed to a near-point world, as most jobs are now confined to tables and chairs, working on computers, and small office boundaries.
