Beat the Blue™
Blue light is the most harmful light to our eyes and it’s almost everywhere.(1,2) While it’s impossible to completely avoid exposure to blue light, there is something you can do to help protect your eyes today and maintain healthy vision for a lifetime.
What is Blue Light?
Blue light is a component of visible light and you are exposed to it without even realizing it.(1,2) Blue light is not easily filtered by your eyes and overexposure can negatively impact vision.(3,4)
It’s Everywhere, and Unavoidable
Nearly every source of light(2)—whether natural or artificial —emits harmful blue light.(1,2,5) Your eyes are exposed to it all day long, both indoors and out and as the use of technology and digital devices increases, the risk to your eyes increases too.(1,2)
More Digital Devices = More Blue Light
- 60% of Americans use devices more than 5 hours daily(6)
- 76% of Americans use devices in the hour before going to sleep(6)
- 70% of Americans use 2 or more devices at the same time. 75 percent of those people report experiencing symptoms of digital eye strain(6)
- 33% of children use devices 3+ hours daily(6)
- 87% of millennials use 2 or more devices at the same time(6)
- 37% of millennials use devices 9+ hours daily(7)
More Blue Light = Likely More Eye Damage
Not only could blue light damage your eyes now, but it can possibly affect your vision in the long-term.
Digital Eye Strain Short Term Effects(6,8,9),
- Blurred Vision
- Dry Eyes
- Eye Strain
- Eye Fatigue
Blue Light Long Term Effects (3,4,10)
- Retinal Damage
- Poor Glare Recovery
- Reduced Visual Performance
- Age-related Eye Conditions
What Can You Do?
Make lutein part of your daily routine.
Found naturally in certain fruits and vegetables, lutein and zeaxanthin are the ONLY nutrients that are deposited by your body specifically into your eyes to that help filter harmful blue light.(11-13) Unfortunately, your body doesn’t make lutein or zeaxanthin so you need to get these important nutrients through food and/or vitamins containing lutein and zeaxanthin.(14)
Lutein and Zeaxanthin-Rich Foods/Content per Serving(15)
- Spinach cooked – 20.4 mg/cup
- Eggs – 1 large – 0.3 mg
- Broccoli raw- 1.3 mg/cup
- Corn cooked– 2.4 mg/cup
Are You Getting Enough?
Probably not! Studies suggest that you need 10 mg of lutein and 2 mg of zeaxanthin each day. (16,17) Most people only get 1-2 mg from diet alone.(18) Taking a daily vitamin with lutein and zeaxanthin can help ensure you are getting the eye nutrients you need.
