Do You Have Computer Vision Syndrome?

Do You Have Computer Vision Syndrome?
Approximately 90% of us do.
According to the latest study published in the top science journal Nature, most people who use screen devices for more than 3 hours per day develop Computer Vision Syndrome (CVS).
Blurred vision, visual fatigue or discomfort, diplopia, dry eye, redness, eye strain, irritation, headache, and shoulder, neck, and back pain are all symptoms of CVS.
The reasons for this are listed below, and further down, explained what one can do to avoid additional pain and long-term effects.
CVS has many factors:
• poor sitting posture,
• insufficient eye-to-screen distance,
• insufficient working procedures,
• incorrect viewing angle and distances
• age,
• medical conditions,
• long duration of computer usage,
• improper workstations,
• poor lighting,
• contrast,
• slow refresh rate,
• glare of the display,
• excessive screen brightness,
• imbalance of light between the computer screen and the surrounding working room.
What can help you:
1 - The 20/20/20 Rule
The 20/20/20 rule states that you should look at your screen for 20 minutes before looking at something at least 20 feet away for 20 seconds. (Six meters equals 20 feet).
2 - Ensure better lighting
Overexposure to bright light frequently causes eye strain. When using a screen, the background lighting should be half as bright as it is in most modern offices or spaces.
3 - Blink more
You may not realize it, but you'll be blinking less than usual as you stare at that screen.
Blinking is important for our eyes because it keeps them moist and prevents irritation and dryness.
4 - Take a lot of breaks
This is beneficial not only to the physical health of your eyes but also to your mental health.
Take at least one 10-minute break every hour.
5 - Move, shake and change up your workstation
Many screen postures are static or repetitive movements, such as switching between screens. It can be harmful to constantly twist your head in one direction or to remain motionless. Twist, shake, move, and change how and where you work, such as by using a standing desk.
6 - Adjust screen brightness & use night mode
This holds true for both your computer and your mobile phone.
7 - Get blue light computer glasses.
Wearing specially designed computer glasses to reduce your exposure to harmful blue light emitted by screens is another excellent way to protect your eyes from computer screens.
