Orange-tinted glasses may make it easier for some people to fall asleep, by blocking blue light from electronic screens, new research suggests.

The glasses, which cost about $8 a pair, are growing in popularity but remain largely untested, The New York Times reports.

Studies have shown that the light from TVs, computers, mobile phones, and tablet screens — especially from the blue part of the spectrum — blocks the body’s production of melatonin, a hormone that naturally helps people fall asleep.

Some research suggests orange-tinted glasses can help.

Other approaches that may help: use a small screen rather than a large one; dim the screen and keep it as far away from the eyes as possible; and reduce the amount of time spent reading the device, experts advise.
