Operating on the premise that protecting eyes from blue light, such as that emitted by computers, TVs, and electronic tablets, will promote restful sleep, Dr Jim Gallas has released “Sleepy Time glasses” to the public. Distributed through online retailer Debby Burk Optical (, these glasses start at under $50.

Gallas, inventor of Melatonin Production Factor (MPF) lens technology, says because blue light suppresses the production of melatonin during the evening, any filter that reduces blue light will reduce this suppression, thereby allowing healthier sleep. He adds that earlier blue light-blocking products had the negative side effect of distorting colors, but says Sleepy Time glasses actually enhance colors.
