Dangers of Blue Light


SoCal Eye recognizes the month of March as Workplace Eye Wellness month, reminding both employers and workers of the importance of wearing certified eye protection. A danger to eyesight that often goes unnoticed is the blue light emitted by tablets and computers. Sunlight is the largest source of blue light, but studies have shown that too much exposure to blue light from screens, such as your computer monitor, TV, or tablet, can cause digital eyestrain or damage to the retina. Symptoms of digital eyestrain include sore, irritated eyes or a difficulty focusing. Studies have also shown that continued exposure to blue light over long periods of time has the potential to damage retinal cells, which puts you at risk for developing vision problems later in life, like age-related macular degeneration or cataracts.

However, not all of us can just avoid being exposed to blue light for long periods of time. The use of computers and phones are unavoidable, especially if your job require it, but there are steps you can take to make sure you eyes get the relief they need.

Here are 7 easy steps you can take to reduce your risk of digital eyestrain:

  1. Consider computer eyewear to protect against blue light
  2. Make sure that your surrounding has proper lighting
  3. Minimize the glare on your computer screen to avoid eyestrain
  4. Upgrade your computer monitor – the bigger the better – as well as adjusting the settings on your display screen: brightness, text size, and color temperature.
  5. Do not forget to blink often to help prevent dryness and irritation
  6. Take frequent breaks from your computer screen.
  7. Schedule a comprehensive eye exam with SoCal Eye each year to keep your eyes healthy.
