 COMMON PROBLEMS AND SOLUTIONS TO REGULAR USE OF ICT TOOLS.

1. Eye Strain

Eyes can become strained after staring at a computer screen for a long time, particularly if working in a bad light, in glare, or with a flickering screen.

Fortunately, eyestrain is usually a temporary problem.

Symptoms include:

• Burning or itching eyes
• Blurring or double vision
• Headache
• Fatigue
• Nausea

Solutions

• Use monitors which don't flicker
• Have blinds at the windows so that the sun doesn't shine directly on the screen
• Use suitable lights that disperse light evenly and don't shine on the screen
• Use a screen filter
• Keep your eyes at least 18 inches from the screen
• Regularly look away from the screen and focus on something in the distance
• Take regular breaks - at least 5 minutes break every hour
• Have regular eye tests and wear glasses if prescribed

2. Backache & Neck Pain

Many computer users suffer serious back and neck problems.  This is probably due to a poor posture or an awkward position while sitting at a computer.

Some of the things that people can do to help avoid back pain are:

• 1.Use a fully adjustable chair. The height of the chair and the seat position should be easy to change.

• 2. Use a footrest so that the legs are kept at a more natural angle

• 3. Use a monitor which is adjustable. Position it so that the neck doesn't have to bend.
• 4. Take regular breaks and walkabout.
• 
  

3. Repetitive Strain Injury (RSI)
