What color LEDs are bad for your eyes?

According to a report by The French Agency for Food, Environment and Occupational Health and Safety (ANSES), the blue light emitted through LED lights can damage the retina in the eye.

Are blue LEDs harmful?

The ANSES report shows that exposure to blue light can cause permanent damage to the retina. Light-induced retinal damage can result from viewing either a very bright light for a short time (acute exposure) or a less bright light for a longer duration (development of Age-Related Macular Degeneration – AMD).

Are blue LED lights healthy?

Exposure to high levels (high intensity or a long time) of blue light can be toxic; however, short-term use is generally safe [21]. Exposure to blue light at night has a negative effect on our health, due to the disruption of the circadian rhythm.

Is bluelight harmful to your eyes?

What is the healthiest LED color?

A 2017 study reported in the scientific journal PLOS ONE (3) found that blue lighting leads to post-stress relaxation three times as quickly as conventional white lighting. Blue light's potential calming effects have been observed outside scientific studies as well.

What is the healthiest LED light color?

Red light. Red light is by far the best calming light color for sleep. Choosing a red light as a nightlight ensures that you don't disrupt your circadian rhythm. So switching to a red light a few hours before going to bed will surely help you fall asleep easier.

Does blue LED cause aging?

Blue Light and Your Skin. Research shows blue light from electronic devices can lead to changes in your skin cells, including cell shrinkage and death. These speed up the aging process. Even exposures as short as 60 minutes can trigger these changes.

Do blue LEDs emit UV?

Although most types of LED lighting do not emit any UV light, brilliant blues do emit a small amount. However, the phosphor reduces this to such a small fraction of the already small amount, the amount emitted is essentially negligible.

What do blue LED lights do?

Blue light wavelengths produced by electronics and overhead lights boost attention, reaction times and mood, according to Harvard Medical School. This can be great for the daytime when the body needs to be alert, but at night it can become a problem.

What is the best LED color to sleep in?

The best night light colors for sleep are red and amber, as they are warm and soothing colors that promote a good night's sleep. It's thought that colors close to red on the light spectrum stimulate melatonin production. Red light has a lower color temperature than regular sunlight, making it ideal for sleep.

What color LEDs make you awake?

Blue light has the strongest impact. Exposure to blue light (and white light, which contains blue light) during the sensitive period can make it difficult for you to fall asleep and stay asleep. Exposure to white light during the day can have positive effects, including boosting alertness and mood.

Is blue light and UV light the same thing?

At the other end of the visible spectrum, past the visible blue light, is a light wave that's too short for us to see. We call these waves blue-violet, or ultraviolet (UV) radiation. Since UV rays have higher energy than visible light rays, high exposure to them can cause suntans, sunburns, and eye damage.

Are LED black lights safe?

Exposure to UVA from black lights is well below the recognised safe limits and is not hazardous to people using them, working in their vicinity or who have them in their home. Exposure from black lights would be much lower than your exposure to UVA outdoors.

What does blue LED do for your face?

Blue LED light is most often used to treat acne. It may do this by reducing activity in the sebaceous glands, so they produce less of the oil that can plug the hair follicles, leading to acne. Blue light may also kill acne-causing bacteria known as Cutibacterium acnes.

What does blue light do to the human brain?

Blue light fools the brain into thinking it's daytime. When that happens, the body stops releasing a sleep hormone called melatonin. Melatonin is nature's way of helping us wind down and prepare for bed. The body starts releasing it a couple of hours before bedtime.

Can you overdo LED light therapy?
