If blue light keeps you awake, why do airplanes use blue lights at night?

I was part of a study once to see the effects of red vs blue or blue/green light on National Guard flight crews who might work a day job, then fly at night for their guard unit. Blue/green was easier to adjust to and maintained better night vision than other lights

Do fluorescent lights give off blue light?

Since they do not appear yellow like a bug light, yes, they give off blue light.Blue light, unlike what a lens company has claimed, is not harmful. If it were, everyone would be blinded by going outdoors where the amount of blue light is hundreds of times more than smartphone screens, and no one could ever sleep again. Compact fluorescent bulb spectrum.

Blue-light filtering IOLs

Blue light filtering IOLs filter the UV and high-energy blue light present in natural and artificial light, both of which can cause vision problems; however too much filtering of blue light can increase depression, especially in the winter months (SAD). The trademarked "Natural Yellow" material is available in three hydrophilic IOLs. Dr. Patrick H. Benz of Benz Research and Development created the first IOL material to incorporate the same UV-A blocking and violet light filtering chromophore that's present in the human crystalline lens in order to attempt to protect the retina after cataract extraction of the natural crystalline lens. A Cochrane Review found little evidence of important differences between blue‐light filtering and non‐blue‐light filtering lenses for protecting the macula (back of the eye) after cataract surgery. This was due to studies being too small and too short‐term to provide reliable evidence.

Seeing the Light — How Blue Light Can Benefit Us

Humans have evolved to rise with the sun and go to sleep after sunset. Also known as our circadian rhythm, this 24-hour cycle takes us from sleepiness to alertness at regular intervals. A well-functioning circadian rhythm helps us rise, get through our day effectively and fall asleep at night. Blue light is key to a well-functioning circadian rhythm. Roughly twelve hours after our eyes are exposed to blue light, melatonin is released in the brain, leading to drowsiness and sleep. The good news is that the sun is well equipped to give us blue light between 7:00 a.m. and 11:00 a.m. (when light is 450-500nm wavelength). And when the sun is not available (think Alaska in the winter and very rainy places), folks have figured out how to get blue light from man-made lamps. Problems arise when we are exposed to blue light when we should not be. Blue light comes from lots of man-made sources - namely, our screens. Television, computers, phones and digital clocks all emit blue light and this light is hitting us at all hours - not just that ideal morning segment - throwing off the ideal 12-hour sleep/wake cycle. So, avoid looking at screens late into the evening. While many phones have a "night mode" or "night shift" that reduces blue light emissions, it's still not advisable to bring your phone or tablet to bed. Blue light therapy helps break down bilirubin into products that are easily eliminated, reducing jaundice in newborns. Blue light is antibacterial and can decontaminate hospital and clinic rooms. It can kill bacteria that causes hospital-acquired infections. It can also kill skin bacteria and be used to improve the symptoms of psoriasis, reduce eczema lesions and treat atopic dermatitis (under the care of a dermatologist) Exposure to blue light can positively affect us in many ways from better sleep to fewer skin blemishes. Avoid blue light at night to maintain a healthy circadian rhythm. And too much exposure can also affect eyes negatively. Blue light harmful effects: • May increase the risk of macular degeneration The takeaway here, get outdoors in the morning and let the sun work its magic. Consider taking a morning walk (it's one of the positive morning rituals our readers identified) outside and you will not only set yourself up for a great night's sleep, but a positive day, too.
