It actually all depends on who you speak to and how long they have had to or how well they have visually adapted to using and operating display screen equipment, how long and/or often, they are on screen, in a typical day including outside of work hours, and whether or not they are off-screen at least an hour or two before, not just going to bed but, going to sleep.

Like many other conditions, mostly with names ending in an ‘ia’ and, that are, more or less by and large “subjectively” reported, there are as many opinions as there are professional, academic and/or self-proclaimed experts on the subject either for or against “ it “.

Studies have proven even mild discomfort reduces the efficiency of work, and thereby productivity.

There is also now little to no doubt that workers using computers as part of their daily work will suffer, to a greater or lesser extent, from visual discomfort, eye-strain, Computer Vision Syndrome (CVS), Screen Fatigue and, over time, Work related Upper Limb Disorders (WULD’s) or Muscular Skeletal Disorders (MSD’s).

Health and Education professionals have suggested the need for teachers and students to be conscious of the problem when using computers. As the use of computers has become universal in higher education institutions and the workforce, the prevention of eye-strain, Computer Vision Syndrome or Screen Fatigue and associated discomfort, harm or injuries should be made part of the mainstream risk management.

It is not a problem founded in the individual’s vision: rather it’s the way the user’s computer screen is initially set up. All people are different, all computer screens are not the same and will need optimising for the operator.
