One study reported that individuals who had used a computer for an average of 4-8 hours per day over five years were 1.14 times more likely to develop open-angle glaucoma than those who used computers for 8 hours in front of a computer each day were 1.38 times more likely to develop glaucoma. bending forward to view the screen more clearly.Īvailable evidence also suggests that there is an increased risk of open-angle glaucoma associated with regular computer use for extended periods. Nonocular symptoms such as headaches, shoulder, neck or back pain may also result from over-correction or accommodation postures that aim to reduce eye strain (e.g. Temporary change in ability to see colours and/or.Dry eye syndrome (keratoconjunctivitis sicca).Temporary vision and eye problems which are associated with computer use include: There now exists a substantial amount of evidence that computer use is closely associated with various eye disorders, which are collectively referred to as computer vision syndrome (CVS). Looking at the computer screen for long periods of time, particularly without breaks andĮye and vision problems associated with computer use.Sitting an inappropriate distance from the screen (too close or too far).Working with background lighting which is too bright.Using a screen which is glary or reflects other images.Viewing images or characters on the screen which are too small.The main risk factors for developing eye or vision problems through computer use are: Computer users also have a decreased blink rate and increased ocular surface exposure due to horizontal viewing of the screen, which can increase the tendency for their eyes to become dry. In addition to computer use, other factors that contribute to eye and vision disorders in an office environment include air conditioners, ventilation fans, static build up, airborne paper dust and contaminants. The use of computers allows many of these varied tasks to be combined and performed more efficiently from the desktop, thus reducing the amount of ‘natural’ breaks for office worker’s eyes and increasing the risk for the eyes to become strained. Office work previously included a range of activities, such as typing, reading, writing and filing, which involved a variety of movements and visual demands, and reduced the risk of eye strain. Like the human body, the human eye is not designed for looking at a computer screen for prolonged periods.
