Blue-Light Blocking Glasses Sleep Circadian

  • Blue Light Blocking Glasses for Sleep

    Did you know that exposure to light suppresses the secretion of melatonin, a hormone that influences sleep and circadian rhythms? Exposure to light at night is one of the reasons a large number of people don't get enough good-quality sleep. Light of any kind can affect the secretion of melatonin but blue light at night activates a pigment called melanopsin and can disrupt melatonin and sleep more powerfully.

    The average person spends 7 hours a day in front of some kind of screen. With our blue light blocking glasses you will no longer have to struggle for hours before falling asleep. Our amber-color amber color lenses filer blue light out and are great for use in the evening. There is blue light in LED lights, TVS, and screens.

    Our blue light glasses are ideal for people who need to work late on a computer, people who watch TV, and any person who is exposed to excessive illumination in the evening.

Restricting short-wavelength light in the evening to improve sleep in recreational athletes - A pilot study

“At the end of the study, the amber lens group experienced significant (p <.001) improvement in sleep quality relative to the control group and positive affect (p = .005). Mood also improved significantly relative to controls”

“subjects completing the study showed subjectively reduced anxiety and improved sleep quality on multiple measures”

“Results indicate that blocking short-wavelength light in the evening, as compared to habitual light exposure, significantly shortened subjective sleep onset latency (Δ = 7 min), improved sleep quality (Δ = 0.6; scale 1-10), and increased alertness the following morning”
