What are the main causes of Computer Vision Syndrome (CVS)?

  1. Overexposure to blue light on screens
  2. The flicker emitted by HEV waves reaching our eyes

These are the two main causes of CVS that makes it difficult to focus and wears down our vision overtime.

The worst cases of CVS makes it harder to see contrast and blurs our vision and ability to distinguish things clearly. 

Reduce your experience with CVS or reduce it altogether by wearing Iris blue light blocking glasses.

Have you been experiencing Computer Vision Syndrome (CVS)?

Here are the most common Computer Vision Syndrome (CVS) symptoms:

  1. Exhaustion and eye discomfort
  2. Dry and itchy eyes
  3. Double or blurred vision
  4. Headaches and migraines
  5. Neck and shoulder tension

Limiting our screentime to just a few hours per day could reduce the chances of CVS, but it may not be possible if many aspects of our lives involve a screen. 

If you have already been overexposed to blue light, certain symptoms of CVS may require a lot more time to disappear.


How to check if you have Computer Vision Syndrome (CVS):

A detailed eye examination includes the following can help with your CVS diagnosis:

  • Eye Examination: a refraction is used to find out if there may be any potential refractive errors in the sight and diagnose any untreated vision problems (such as astigmatism, farsightedness or nearsightedness).
  • Visual acuity Test: assessing if the near or distance vision has been affected.
  • Eye Coordination Test: assessing how your eyes work together, if they move in unison and if their focus is effective.
  • Eye Coordination Test: this is to test how quickly or slowly your eyes move and whether your focus is effective.
  • Visual acuity Test: Your near and far sighted vision will be tested to see how your eye power has been affected.
  • Eye Examination: A certified optometrist or ophthalmologists can carry out an official test to diagnose you with CVS or other issues.

    Avoid contracting Computer Vision Syndrome (CVS)

    It is nearly impossible to avoid a screen in today’s lifestyle. The first mass-market smartphone was launched in 2007, and ever since then we’ve been unable to tear our eyes away from damaging blue light as we like our friends’ posts, email our colleagues, and watch the latest inspirational talks. 

    While social connection and work are important, hours of exposure to blue light can be harmful in the long run. Symptoms like blurry vision, tired and dry eyes, and headaches are part of Computer Vision Syndrome (CVS) which is caused by too much screen time.

    The best way to prevent CVS while still using our phones and computers for work and play is to wear blue light blocking glasses to filter out the damaging effects of too much screen time. 

    Some symptoms of CVS could be permanent if you have already been exposed to blue light for long periods of time after many years. However, most CVS symptoms can reduce and disappear altogether if you wear blue light blocking glasses and/or be mindful of your screen time and spend more time offline.

    It only takes a few hours of downtime away from screens offline to feel the effects of CVS wear off. If you combine a healthy amount of downtime with blue light blocking glasses, you can significantly reduce the effects of CVS on a daily basis. 

    Should you have any long-term concerns over symptoms of CVS, be sure to visit an optometrist if symptoms cause discomfort and persist.
