Help Reduce Exposure with Blue Light Glasses*

WHAT CAN YOU DO?

More than half of U.S. adults – 60 percent – spend a minimum of six hours a day, every day on phones, tablets and computers, so it's important to practice good habits to keep your eyes safe from blue light. Because we use our electronic devices so regularly, we are gradually being exposed to more sources of this light for longer periods of time.

• Invest in Blue Light filtering lenses
  These lenses are designed to reduce exposure to blue light from the sun and your digital devices. They're available for prescription and non-prescription glasses.
• Use good ambient lighting
  Keep balanced lighting around your computer work area to avoid high contrast and reduce glare.
• Avoid using digital devices an hour before trying to sleep
  Don't take phones and tablets to bed. The blue light from your phone's display may keep you awake.

Many adults who use devices regularly and who experience eye discomfort didn't do anything to ease their symptoms. Schedule an eye exam to make sure you're doing everything you can to reduce exposure to blue light in your daily environment.
