Protect Yourself While Gaming - Tips to avoid eye strain and Proper sitting tips while playing games
by: Paul Wilson
Gaming means long hours at the computer. Self absorbent and an obsessive hobby, incorrect habits and posture are detrimental to health. Problems like musculoskeletal injuries, eyestrain, and disabilities of the hands and wrist like, RSI or Repetitive Strain Injury are common.
Bad posture causes: pain, stiffness of joints, weakness, bad circulation, as well as swelling.
Ensure that:
• The desk is designed especially for computers.
• While seated, the feet are flat on the floor; arms and thighs are parallel to the ground; back is straight; and the arms don’t have to stretch out to reach the keyboard or mouse.
• The keyboard height is such that the elbows are parallel to the ground and level with the keyboard. An ergonomic keyboard is recommended.
• The spine maintains its ‘S’ curve when seated, so use an ergonomic chair and if required, a footstool.
• The mouse is placed at the same height as the keyboard. Use your whole arm not just the wrist when operating the mouse.
• Typing is done with light fingers. The wrists should be flat and not angled to the left or right. To avoid nerve compression the elbow must not be angled more than 90 degrees.
• The arms are raised off the keyboard as often as possible.
• Tasks are alternated so that you are not typing or clicking the mouse continuously.
Another factor is eye strain. Extended computer use can cause: blurred vision, focusing difficulties, as well as headaches.
Reduce risk by ensuring that:
• The light source is angled from the side. The primary light source must not shine on the face or directly on the screen. Lighting should have a 10:3 ratio screen characters should be 10X brighter than background and room lights should be 3X the screen brightness. Use a shaded copy lamp to avoid screen reflections.
• Reflections and glare are eliminated by using an antiglare screen and by tilting the monitor slightly.
• The monitor must be centered so that neither the body nor neck is twisted when viewing the screen.
• The screen is of good quality. The text should be sharp and nor distorted. Change the resolution to a comfortable font size.
• The monitor is a suitable distance away.
• The screen is at eye level or lower.
• Brightness and contrast are reduced to suitable levels.
It is important to:
• Break concentration by looking away from the monitor at far away objects at least once every 15-20 minutes.
• Pause in between to blink your eyes rapidly. This will lubricate the eyes and prevent dryness.
• Schedule regular eye checks.
• Monitor blurred vision, headaches, red eyes, or watering eyes.
• Splash water and wash your eyes at least 3-4 times a day.
• It is advisable to take frequent breaks, either do stretches or take a short walk once every hour for 10-15 minutes.
• Use a well ventilated room.
• Reduce emission in laser printers, photocopiers, and scanners.
Problems can be eliminated and the risk reduced by inculcating good posture and working habits.
