“We’re spending more and more time in front of the computer screens. “The reality is that most of the problems we’re having with computers and eyestrain isn’t from blue light it’s from how we use the computers,” said Mohsenin, who also treats patients at the Robert Cizik Eye Clinic and Memorial Hermann-Texas Medical Center. Scientists at the University of Manchester published a study in Current Biology that showed that yellow light disrupted sleep patterns in mice more than blue light.

However, a growing body of research is challenging the notion that blue light is bad. This helps us stay alert and focused during the daytime, but it can interfere with sleep. Studies have shown that blue wavelengths can disrupt the body’s natural circadian rhythm by suppressing melatonin production levels through certain non-image-forming photoreceptors in the eye called melanopsin, a type of photopigment in retinal cells.

It’s hard to recommend something without knowing more details about it.” In fact, I would say that we don’t know if there’s any potential harm in wearing blue block glasses. “We don’t really have any data that supports blue blocking glasses as being better for your eyes when you’re using a computer. “There’s really no evidence that help,” said Amir Mohsenin, M.D., Ph.D., assistant professor in the Ruiz Department of Ophthalmology & Visual Science at UTHealth‘s McGovern Medical School. The ubiquitous bedtime use of laptops, smartphones and tablets can throw off our circadian rhythms, prompting people to look to a fairly unregulated market for a solution to block blue light.Īccording to an American Academy of Ophthalmology report, “it’s not necessary to spend money on special for computer use.” Popular eyewear companies, such as Warby Parker and Felix Gray, are selling lenses that claim to filter out blue light emitted from electronic devices to reduce eyestrain, headaches and sleep issues. Blue light glasses are among the hottest trends in eyewear.
