EYE PROBLEMS

People nowadays often spend hours in front of computer everyday, which lead to eyestrain, blurred vision, and even headaches and shoulder pain; actually these are warnings from our body.

If your eyes regularly become dry and red, and you just let it become a habit, your eye not just apparently turn black and turn red on the eyeball. Time after time, you need to face the problems of vision degeneration and poor coordination of visual nerves.

EYE PROBLEMS CAUSES IMPROVEMENT MEASURES
  • Eye strain
  • Blurred vision
  • Slow in focusing
  • Double vision
  • Headaches
  • Blurred letters on the screen.
  • Reflection of ceiling light, or glare from windows.
  • Ciliary muscle strain caused by looking at a near screen for too long.
  • Frequent change of focus as eyes move to and fro between screen and document causes ciliary muscle strain.
  • Frequent adjustment and accommodation is needed as eyes move to and fro between document with “black letters on white background” and screen with “white letters on dark background”.
  • Symptoms such as eye strain, blurred vision, slow in focusing, double vision, headaches appear when the ciliary muscles are tired and cannot focus properly.
  • Use lampshade to divert ceiling light downwards to avoid glare.
  • To avoid reflection and glare from the screen, do not place the screen by the window and do not sit with your back facing the window. Consider using curtains to prevent too much light coming in from outside.
  • To avoid reflection and glare from the table, use table and countertops with non-reflective matt surfaces.
  • Choose dark letters and light background on the screen to enhance contrast, and use a filter to reduce the brightness.
  • Regularly wipe the screen with tissue paper or dry cloth to remove dust that affect the clarity.
  • Place the screen slightly below eye level so that the eyes are looking slightly downwards.
  • Document and the screen should be at the same distance, around 40-60 centimeters, to the eyes. This saves the eyes from frequent accommodation.
  • Use accessory light for the document if needed.
  • Take 5-10 minutes rest after using the computer for 30-40 minutes.
  • Itchy eyes
  • Red eyes
  • Watery eyes
 
  • Heat generated and disperse from the back of the computer monitor accelerates tear evaporation.
  • Air-conditioning in computer room dries up the air and accelerate tear evaporation.
  • Over concentration on near screen reduces blinking frequency, which leads to inadequate tear replacement and makes the eyes itchy and red.
  • On the other hand, dryness and itchiness of eyes can stimulate excessive tear production, causing watery eyes.
  • Avoid placing the back of the monitor too close to wall, otherwise the heat will be reflected towards your eyes.
  • Avoid air-conditioning or setting the temperature too low, as long as the computer is not damaged.
  • Intentionally increase the frequency of blinking so that tears can be swept over the eyes for lubrication and moisture.
  • Use artificial tear to lubricate the eyes if needed.
 

If you find yourself suffering from any of the above problems, you may have visual defect. Please have your eyes checked as soon as possible.
