The Hazards of BlueLight

We’ve all become accustomed to searching for hazards in the world around us. When driving,we stop at red lights. At the movies, we notice the exit signs. Our eyes are trained to see most of the warnings around us, but they can’t see everything.

Blue light, invisible to the eye, is a growing concern in our modern lives. Computer screens, phones, televisions all emit blue light,and in today’s world, we simply can’t avoid our technology.

New research demonstrates the problems associated with bluelight including:

  • Digital eye strain – Digital eye strain typically includes symptoms such as, dry,irritated eyes and the inability to focus our eyes.
  • Increased risk of macular degeneration – Research suggests that increased blue light exposure can also cause the breakdown of cells in the macula of the eye, leading to macular degeneration.
  • Lower levels of melatonin – Research also suggests that artificial blue light leads to lower levels of melatonin, making it difficult to maintain a regular sleep cycle.

It is important to realize that not all blue light is bad for you—natural blue light, for example, increases mood and alertness. Still, measures can still be taken to reduce the amount light we are exposed to everyday.

Screen covers and protective lenses (lenses made specifically for computer use or lenses with ant-reflective coatings), can both provide protection from the effects of blue light, so if you have questions about blue light and how ton protect your eyes, contact the professionals at Spex Expressions today.
