Computer vision Syndrome
Many people spend a considerable part of their working day in front of a computer monitor (VDU). This environment can lead to the user suffering from Computer Vision Syndrome (CVS).
Although there is no reliable evidence to suggest that computer monitors are damaging to the eyes, it is true that users complain of eyestrain more than non-users.
Unlike characters on a printed page, computer screen characters are made up of many pixels, or tiny points of light. These pixels are brightest at the center of the screen and gradually reduce in intensity as you approach the sides of the screen. Your eyes focus differently to make out the characters on the edges of the screen compared to the characters at the center. This constant adjusting of focus creates fatigue and eyestrain that may damage your eyes over time.
Computer vision syndrome can develop if you spend over two hours a day at a computer. This is likely to be owed to fatigue through causes such as:
- Insufficient and infrequent rest periods
- Incorrect positioning of the screen or documents
- Unsuitable lighting
- Poorly designed work area
- An uncorrected eyesight fault such as long sight, short sight, astigmatism, or presbyopia
- The eyes not working ‘as a team’
- Loss of focus
- Burning eyes
- Tired eyes
- Double vision
- Blurry vision
- Neck and shoulder pain
Any of these conditions can be overcome through good design of the working environment, taking frequent breaks, adjusting your screen settings, positioning, lighting, and the use of correct spectacles and lenses.
