Exposure to Blue Light Could Increase Your Risk of Age-Related Macular Degeneration

By Mid-Coast Optical | Feb 12, 2014


If you’re like many Americans, your tablet has become an indispensable part of your day. In fact, a recent report found that Americans spend almost 2 ½ hours on their tablets and smart phones every day. But have you ever thought about the impact digital devices could have on your eyes?

There’s a pretty good chance that the screen of your beloved tablet is powered by LED (light-emitting diode) lights. While it certainly saves energy, prolonged exposure to the light emitted from LED technology could be bad for your eyes. The light from LEDs exists in the blue and violet end of the visible-light spectrum. This “blue light” is the most intense form of light visible to the human eye, and new studies have shown that prolonged exposure can impact your eyes and vision. Here’s what you need to know:

  • Exposure to blue light can cause significant damage to retinal cells.

  • Your risk of age-related macular degeneration is increased with exposure to blue light.

  • Prolonged exposure to blue light can aggravate symptoms of epilepsy and migraines..

  • Some evidence suggests that prolonged exposure to blue light may reduce the retinas’ sensitivity to color.

Luckily, there’s no need to end your relationship with your digital device. Reduce your risk of side effects by incorporating these simple steps into your everyday digital routine:

  • Avoid prolonged work on a tablet.

  • When using a tablet observe the 20/20/20 rule.

  • Protect your children’s eyes by limiting their screen time to only one hour a day.

  • Schedule an annual eye exam to find out if you’re at risk for over-exposure to blue light and diseases including age-related macular degeneration.

  • Talk to your eye doctor about Crizal® Prevencia™ lenses.  They’re specifically designed to protect eyes from harmful blue light and UV rays.
