And if you’re like us, you’re curious about the impact all this blue light is having on your eyesight. You’ve heard that blue light keeps us awake at night, suppressing melatonin that nudges us to sleep naturally—and you definitely know at least one person with blue-light-blocking glasses. Chronic overexposure to blue light is what we need to watch out for. While sunlight can be healthy for us for the reasons above, bombarding our eyes with artificial blue light from LED-backlit screens up until we close our eyes at night can disrupt our circadian rhythm. Macular pigment is comprised of two carotenoids called zeaxanthin and lutein that we can only get from our diet in foods like leafy green veggies, carrots, pumpkin, and egg yolks, and this pigment in our eyes absorbs high-energy blue light3. The denser the pigment, the more blue light is blocked. What’s compelling is that scientists and ophthalmologists are currently studying what happens after supplementing with these two carotenoids, and the results of several placebo-controlled clinical trials4 reveal that as little as six months5 of supplementing zeaxanthin and lutein can improve macular pigment density. Eye Shield, a daily supplement from Objective, contains the clinically researched dose of both carotenoids to help protect your eyes from the negative effects of blue light from digital devices, help reduce eyestrain and eye fatigue, and support healthy vision long term. The cool thing is, it isn’t in capsule form—Eye Shield comes in a delicious, easy-to-take stick pack that you can mix with a liquid like juice or a glass of water.
