Repetitive Strain Injury (RSI) is damage to the fingers, wrists and other parts of the body due to repeated movements over a long period of time, often while sitting at a computer screen.
For example, tendonitis is an inflammation of a person's tendon and can be caused by prolonged use of a keyboard.
Solutions:
Make sure your posture is correct
Use wrist rests
Take a five-minute break from typing every hour
Back strain
Many computer users suffer serious back problems. This is probably due to poor posture or adopting an awkward position while sitting at a computer.
Solutions:
A fully adjustable chair should prevent poor posture
Footrests can reduce these problems
Screens should tilt and turn to a position that avoids awkward movements
Eye strain
Eyes can become strained after staring at a computer screen for a long time, particularly if working in bad light, in glare or with a flickering screen.
Solutions:
Screen filters can remove a high percentage of rays emitted from a computer screen
Use screens that do not flicker
Take regular breaks - do not work for more than one hour without a break
Lighting must be suitable and blinds fitted to windows to reduce glare
Many employers in different industries, including the computer and software development industry, are obliged to provide their employees with a yearly eye test if they are sitting at a computer screen for more than four hours per day.
