Blue Light Glasses: Office Ergonomic or Hoax Remedy
Blue light glasses have not been around as long as the aforementioned exercise ball, so not as many studies have been able to look into the proposed benefits. However, a 2015 study conducted by the Minamiaoyama Eye Clinic and Department of Ophthalmology found that these claims do hold some weight. In this study, they concluded that blue light blocking lenses actually do reduce eye fatigue. In 2017 another study came out to support these findings.
However, just as many experts have chimed in to negate - or at least question - the magical properties these glasses seem to have. A clinical spokesperson and ophthalmologist for the American Academy of Ophthalmology, Rahul Khurana, states that digital eyestrain and the negative effects of blue light on your eyes are two separate concerns. “We keep on thinking about blue lights from our computers and smartphones, but the reality is we get more exposure from blue light from the sunlight.” To summarize, the short-wavelength blue light isn't the only culprit - our lifestyle is.
Our eyes are locked onto digital devices for hours each day. Whether it be work , binging Netflix, or checking out the latest TikTok, we've created a pattern of behavior that exposes our retina to a concentrated dose of blue light outside of the natural amount our bodies are designed to handle. To escalate this further, we also rarely experience a change in vision depth. The majority of our day is spent gazing at objects no farther than an arms length away. It should come as no surprise then, that a species built for rising and setting with the sun and staring at rolling hills instead of a 58" flatscreen, experiences discomfort with our new way of life. Not to mention, our eyes are one of the most sensitive and exposed organs on our body. We need to take extra care that they don't get damaged or "wear out" prematurely.
What's the solution?
The American Optometric Association recommends a technique called 20/20/20. Every 20 minutes, you should divert your eyes for 20 seconds from whatever device you've been staring and look at something at least 20 fee away. This gives your eyes a chance to relax and re-focus. However, blue light blocking glasses can be a huge addition to this preventative measure! Many doctors recommend wearing the spectacles at night to prevent the short-wavelength light from disturbing your sleep cycle. And following in Pascal's footsteps, even more suggest than there is little to no harm in trying the glasses out, so it makes a lot of sense to buy a pair - even if the research hasn't given a definitive answer yet.
