Orange glasses may help you sleep better

 
 

Orange glasses have been found to block
certain wavelengths of light emitted by
electronic screens which hamper our sleep
cycle, making it easier for us to sleep.
Studies have shown that light from the blue
part of the spectrum, inhibits the body’s
production of melatonin, a hormone that
helps people fall asleep.
A Swiss study of 13 teenage boys showed
that when the boys donned orange-tinted
glasses — also known as blue blockers and
shown to prevent melatonin suppression —
in the evening for a week, they felt
“significantly more sleepy” than when they
wore clear glasses.
The boys looked at their screens for at least
a few hours on average before going to bed,
and were monitored. The findings were
published in The Journal of Adolescent
Health.
Older adults may be less affected by blue
light, experts said, since the yellowing of the
lens and other changes in the ageing eye
filter out increasing amounts of blue light.
But blue light remains a problem for most
people, and an earlier study of 20 adults
ages 18 to 68 found that those who wore
amber-tinted glasses for three hours before
going to bed improved their sleep quality
considerably relative to a control group that
wore yellow-tinted lenses, which blocked
only ultraviolet light, The New York Times
reported.
