Wearing the glasses also improved work performance.Īnother small trial, published January 2019 in the Journal of Psychiatric Research, found that amber-tinted blue light glasses worn for two hours before bed improved sleep for individuals with insomnia. An article published in 2021 in Applied Psychology gathered data from 63 managers and found that wearing blue light glasses improved sleep quality and quantity. In short, because blue light isn’t to blame for the headaches and dry eyes you’re feeling, blue light glasses likely won’t help.īut one thing these glasses do seem to help with is sleep. “And the screen should be two feet away from the face and not smack-dab against your face.” “When you’re staring at a screen, a tablet, your phone, whatever, you don’t blink as much as you would in natural conversation, so the eyes can get dryer,” Frempong says. Those symptoms are more likely due to the way we interact with our devices. “The screen-related issues that people are having with their eyes are indeed more likely related to dry eye, eyestrain - things like that,” says Lauren Branchini, MD, an ophthalmologist at UMass Memorial Medical Center and an assistant professor at UMass Medical School in Worcester, Massachusetts. That’s likely because blue light isn’t the only reason for digital eyestrain. And another small study, published January 2019 in Optometry and Vision Science, found that even though a blue-blocking filter used on a computer screen blocked 99 percent of wavelengths between 400 and 500 nanometers, it didn’t alleviate digital eyestrain symptoms any more effectively than a neutral filter.

“There haven’t been any scientific studies that have proven they have any sort of health benefits,” says Vivienne Sinh Hau, MD, an ophthalmologist at Kaiser Permanente in Riverside, California.Īccording to a trial published in February 2021 in the American Journal of Ophthalmology, blue light glasses worn during a two-hour computer task did not change eyestrain symptoms whatsoever. So far, research doesn’t support the idea that blue light glasses can relieve digital eyestrain symptoms, such as headaches, dry eyes, or blurred vision. What Scientific Research Says About Blue Light Glasses Frempong says.Īccording to the American Macular Degeneration Foundation (AMDF), there's no evidence that blue light can damage the eye, and therefore any claims that glasses offer protection against retina damage or eye conditions like macular degeneration aren’t accurate.īut blue light from screens can negatively affect your sleep cycle and contribute to digital eyestrain, according to UC Davis Health. “We don’t need to be worried about blue light causing damage to our eyes,” Dr. Many people fear too much blue light exposure can permanently damage the eyes or increase the risk of macular degeneration, though research doesn’t support these claims.

The glasses have special lenses that block or at least filter out certain light waves from devices and are also said to protect the retina from damage, according to the Cleveland Clinic. “Especially in the pandemic, with kids doing remote learning, lots of parents have come in asking about them,” says Tamiesha Frempong, MD, MPH, an ophthalmologist with Mount Sinai Hospital in New York City.īlue light glasses are designed to provide relief from the uncomfortable side effects associated with staring at screens. Perhaps unsurprisingly, blue-light-filtering glasses (aka blue light glasses) have risen in popularity over the past year. Blue light is all around us and is found naturally in sunlight and artificially in fluorescent light, LEDs, computer monitors, smartphones, and tablet screens, according to UC Davis Health. It didn’t take long before concerns over blue light exposure began to set in. Everything from work meetings to birthday parties started being hosted on the internet. Many of us have been tethered to our devices for years, but when the pandemic hit in March 2020, nearly every aspect of life went online. If you’re like most adults, you may be spending more time in front of screens than ever before.
