Computer Vision Syndrome (CVS)… A Warning for Digital Era Workers

For further information or Booking..

Computer Vision Syndrome (CVS) is an eye condition that occurs from prolonged computer use without taking breaks for the eyes. If you are someone who spends most of the day working on a computer, you should be aware that you are at risk of developing these conditions.

• Eye Muscle Fatigue

Staring at a computer screen requires a great deal of eye strain to focus the images on the screen clearly. Additionally, frequent eye movements are necessary for reading text, which can lead to eye muscle fatigue when the eyes are used continuously for more than 2-3 hours.

• Eye Symptoms

For individuals who do not have pre-existing vision problems, extended periods of intense eye use for several hours can trigger short-sightedness temporarily. However, for those who already have existing vision problems such as nearsightedness, farsightedness, or astigmatism and do not receive corrective measures, it can exacerbate their vision abnormalities.

• Dry Eye Syndrome

Normally, a person blinks approximately 20 times per minute. However, when using a computer, the frequency of blinking decreases due to the need to focus on the screen. Combined with cool and dry indoor environments due to air conditioning, this can easily lead to dry eye syndrome.

• Light Sensitivity

Whether it’s a computer, smartphone, or tablet, we often adjust the brightness settings differently. However, excessively bright or dim settings can cause discomfort to the eyes. Prolonged exposure to such settings can result in light sensitivity symptoms.

Protecting Your Eyes with These Techniques!

• Adjust the distance between yourself and the screen, ensuring that your eyes are at the top edge of the computer screen or positioned about 20 degrees below the eye level. Maintain a distance of approximately 16-30 inches.
• After using your eyes for approximately 20-30 minutes, take a break for about 2-4 minutes. Every two hours, rest your eyes by looking into the distance for about 15 minutes before refocusing on your work.
• Adjust the brightness of your computer screen to a level that is suitable for your eyes. This includes adjusting the overall lighting in your workspace and avoiding direct reflections on the computer screen.
