Dealing With Computer Vision Syndrome



What is Computer Vision Syndrome

Computer Vision Syndrome (CVS) is a group of eye, vision and other related problems that results from prolonged computer use. Eye fatigue and strain are some of the telltale signs of CVS.

Symptoms of CVS

General Fatigue
Tension
Arm Wrist and Shoulder Pain                                                                                                 Tearing.
Causes of Eye Strain:
Eyestrain, or asthenopia, may be because of several factors; environmental and/or visual conditions associated with prolong focus on close activities such as working on a computer or even reading a book. Note that there are muscles of the inner eye and it has the capacity to tighten, and when it does it may result to eye irritation and the consequence can be headache, fatigue, double vision, red eyes, eye pain, and blurred vision.
What to do

Vision breaks

Take a break, allow your eyes some time to rest. Focus on distant objects at hourly intervals.

Get Suitable lighting
Eyestrain may also be a consequence of excessive internal or external bright lights. Outdoor light sources could be sunlight entering via a window or an intense internal lighting.
  • Avoid all external light rays especially when it reflects on your screen or directly into your eyes. Position your screen so that windows are to the side of it instead of in front or back.
  • Avoid sitting directly opposite a window or a light house that falls directly into your eyes.
  • Avoid use of laptops or other smart device when you are directly under the sun.
  • Reduce interior lighting by using fewer light bulbs or use lower intensity bulbs. If possible,
  • Avoid working under overhead fluorescent lights use floor lamps when possible.                           
Control it at the source
  • Adjust your computers brightness/contrast controls. 
  • Reduce, or eliminate the effects of glare on your computer screen; you can use a monitor glare screen or hood, tilt or change your monitor position.                                                     

Checks You may Need

A.     Inappropriate use of eyeglass
    Are your glasses personally or professionally recommended? If prescribed or professionally recommended, are they “out of date prescription eyeglasses?”.  
B.     Font sizes on the computer screen
    Depending on the condition of your eyes, for instances, small font sizes could cause eye strain if you belong to the class of persons who  have difficulty reading small fonts.
C.     Contrast levels
       Poor contrast between text and background on the monitor can also be a factor.
D.   Obvious screen flickers
