Are you one of the many people who rely on coffee to get yourself going in the morning?
If so, you may now be able to ditch the java and don a pair of psychedelic looking glasses instead. These glasses, called PSiO glasses, have been shown to inhibit melatonin, which is the stuff that makes you sleepy. They work by stimulating your eyes with blue light.
In August 2013, researchers at the University of Brussels wanted to test the effectiveness of PSiO glasses. They conducted experiments on students from 18 to 24 years old. They divided the students into four groups.
One group wore no glasses, one group wore glasses that emitted red light, one group wore glasses that emitted blue light at a single frequency, and one group wore glasses that emitted blue light at a range of frequencies.
The students were all instructed to rest for 30 minutes starting at 10 p.m., because this is when melatonin production normally begins to increase.
Both the single frequency and the range of frequencies of blue light seemed to result in a strong inhibition of melatonin. The students without glasses and the students with glasses emitting red light all showed normal increases in melatonin levels.
The effectiveness of the glasses has to do with something called melanopsin. Melanopsin is a photo pigment in the inner retina that matches the spectrum of blue light. It doesn’t have as much to do with helping us see as with regulating our biological clocks and making us more alert when necessary. Since blue light mimics melanopsin, it has a similar effect.
There are several implications for this study. Blue light and PSiO glasses may be useful for combating jet lag, improving alertness after an all-nighter, studying more efficiently, and getting a boost of energy in the morning without the addictive effects of caffeine.
The catch is that a pair of PSiO glasses will set you back quite a bit at around $400. But perhaps they will pay for themselves by helping you stop relying on those $5 lattes every morning.
