Blue Light Glasses?
Blue light glasses- hype or placebo? There is a dearth of research that blue light glasses do anything to prevent eye disease or reduce computer eye strain from high energy blue wavelengths. In fact, groups such as the American Academy of Ophthalmology have gone on record refuting any computer glasses. “I agree with this assessment”, states Dr. Kaminski. “A person is exposed to more high energy blue wavelength light just by stepping outdoors.”
However, there may be a benefit to your sleep patterns. A 2017 study done by the University of Houston found that participants wearing the glasses showed about a 58% increase in their nighttime melatonin levels. “By using blue blocking glasses we … can improve sleep and still continue to use our devices. That’s nice, because we can still be productive at night,” said Lisa Ostrin, PhD, a professor at the university’s College of Optometry, according to a university news release. And who isn’t on their smartphone, laptop, or other electronic device before bedtime?
