JINS, a popular Japanese eyewear company, recently released their JINS SCREEN NIGHT lenses in the U.S. These glasses were developed to alleviate the negative effects that bright blue light from electronic screens can have on our circadian rhythms, quality of sleep, and how we feel in the morning. Modern gadgets tend to be pretty bright, but looking at them with the naked eye is not always the best idea before bedtime. Blue light hitting the eyes essentially acts as a signal for the body to gauge that it’s daytime, so being exposed to lots of it at the wrong time can be detrimental. JINS sent us a pair of glasses with JINS SCREEN NIGHT lenses to try out for a few weeks. Having seen similar products in the past, we wanted to try out whether we’d experience the benefits that such glasses are expected to provide.
While JINS SCREEN NIGHT treatment can be applied to any lenses that JINS produces, ours was a non-prescription pair that simply blocked certain wavelengths of light. These account for about 60% of blue light, so more than half is reflected and filtered out, making the glasses have a definite yellow tint to them. Wearing these glasses during daytime really gave us a good impression about their effect. The world becomes bright yellow with a certain sharpness that’s hard to describe, but wearing them at night while in front of the screen is quite different.
The glasses slightly dull the pop that bright modern screens produce, and at first seem like they are harming image quality. We certainly don’t recommend reviewing CT scans with these glasses, but if you need to get some emailing done or catch up on some reading, they won’t cause you any troubles. As a matter of fact, late at night their effect seems soothing and cuts the harshness of a bright screen, letting you work on things with less strain on the eyes. Over the few weeks we’ve been testing the glasses, we found that we tended to reach for them every time we sat down at the computer during the evening hours. They’re light, unintrusive, and do a good job at preventing harsh light coming in while not impacting image quality significantly.
As far as sleep quality goes following wearing these glasses, that would require a controlled experiment with a number of people. While our time with these glasses certainly cannot be considered a proper study, JINS does point to one recently conducted by scientists from Keio University School of Medicine and Tokyo Medical and Dental University that showed a “significant” increase in melatonin production at night and improved sleep quality in a small cohort of adults that used JINS SCREEN NIGHT.
There is software that will moderate how much blue light is emitted from computer screens based on time of day, but it only works on certain devices and doesn’t provide a universal solution. And there are other glasses manufacturers that claim similar benefits as JINS SCREEN NIGHT. We won’t doubt them. Our experience with the JINS glasses has been quite positive and they’ve become a part of an evening routine. As more people these days are logging in on their computers, tablets, and smartphones in the late evening hours, we expect a wider adoption of light management tools such as JINS SCREEN NIGHT among the population.
