If you are having trouble sleeping or experiencing very light sleep, the answer to your sleep problems could be REM Sleep Better Glasses designed with proven blue light-blocking amber lenses. You see, exposure to artificial light at night from computer screens, cell phones, tablets, television, LEDs, fluorescent lights, and incandescent lights inhibits melatonin production, the hormone that tells your body it's time to sleep. Without melatonin, your body's biological clock, the circadian rhythm, believes it's daytime and NOT nighttime. The result is insomnia and disrupted sleep. Blue light naturally boosts attention, alertness, and mood. So, naturally, it's a good idea to block out blue light before you sleep. Studies at Harvard Medical School, the University of Toronto, JAAMA Neurology, and the American Macular Degeneration Society all show that exposure to blue light disrupts melatonin production leading to irregular sleep patterns. We all know that NOT using your phone, NOT watching TV, or walking around in total darkness in your house is not possible! So, the only way you can realistically limit exposure to blue light is to wear REM Sleep Better Glasses. Without exposure to blue light, your body will adjust itself to the night. REM Sleep Better Glasses are also excellent sunglasses and offer 100% UV protection. During the day, the amber-colored lenses filter out blue light and sharpen vision. Amber lenses also reduce glare from shiny surfaces such as cars, chrome bumpers, windows, water, and mirrors. Blue light in the day causes haziness to decrease how far you can see. You will love REM glasses to play golf, drive, fish, tennis, or stroll on the beach.
