More than three decades ago, the introduction of computer transformed the workstations. Moreover, personal computers with Internet capabilities at home has led to a progressive increase in computer usage. This affects our healthy vision.

Before the arrival of computers, office work involved a variety of activities including typing, filing, reading, and writing. Of note is the fact that each activity was sufficiently wide-ranging in the wants of posture and vision. These activities mandated natural break from the previous activity. Nevertheless, the introduction of computers combined these tasks to where most can be achieved without moving from the workstation. While work as such is made easier and faster, it doesn’t fall in line for a healthy vision.

Also, reading text on a paper is generally done while looking downwards; therefore, the eyelid covers a significant portion of the front surface of the eye, thus decreasing the evaporation of tears. Whereas, when we read on the computer screen, the gaze is horizontal which leads to increased evaporation of tears from the eye surface.

Further, compared with an equivalent hard copy reading, a higher percentage of incomplete blinks occur during computer screen reading, which may be the reason for increased visual fatigue. Other eye-related symptoms may include eye strain which includes pain in or around the eyes, blurred vision, headache, and occasional double vision and dry eye, irritated eyes, watery eyes. Brightness or direct glare conditions also cause increased eyestrain and development of neck pain, shoulder pain. The type of light discharged by computer screens affects the alertness and thought performance levels and various 24-hour cycles in one’s body.

Some symptoms like blurred vision need a correction to optimize patient comfort during computer operation.

Some studies have shown that use of font type Verdana for the presentation of individual alphabets on various electronic displays reduces mental workload.

Some other ways in which you can reduce workplace related eye-problems and improve comfort are listed below:

  • Maintain ideal distance from the screen, between 20-40 inches
  • Keep the level of eyes above the top of the screen: Use books to raise and maintain a level
  • Ensure frequent breaks from near-work on the computer screen: 5-10 minutes every hour. Several web alert apps are available to remind you to look away from the screen or take breaks. Install one!
  • Use LCD monitors
  • Use antiglare screen
  • Adjust brightness levels
