The review investigated the potential benefits or harms of “blue-blocking” lenses, marketed to protect against phototoxicity, and found “a lack of high quality evidence” to support their use “for the general population to improve visual performance or sleep quality, alleviate eye fatigue or conserve macular health.”. The Sixth Street bridge over the Los Angeles River looks a bit different with old, left, and new streetlights. If a manufacturer provides it, look for the M/P ratio which provides information on the relative amount of blue light in a light's spectrum. However, other LED lighting sources, including the newest flashlights, car headlights and some toys, produce a whiter and “colder” blue light that is more harmful. The AMA also said that white LED lights are five times more damaging the circadian sleep rhythms than other street lamps. Yet protection from the harmful effects to the retina offered by “anti-blue light” screens, filters and sunglasses varies, and their ability to preserve sleep rhythms is not proven, ANSES also said.

I knew that the AMA report cited lights with a heavy blue content, like "cool white" lights with color temperatures above 4000 K, but I was unaware of the subtleties in the color spectrum associated with lights. For many years, they were only used in electronics but are now found as integral parts of lighting systems,” ANSES wrote in a 2016 report. “It is true that exposure to light in the evening affect sleep and circadian rhythms mostly by inhibiting the synthesis of the sleep promoting hormone melatonin.”, Related Article LED light’s description as cool comes in comparison to traditional home lighting, often called “warm.” The cool light comes from the blue part of the color spectrum. A 2019 report from the French Agency for Food, Environmental and Occupational Health and Safety (ANSES) warned of the “phototoxic effects” of blue light exposure, including an increased risk for age-related macular degeneration. Light and human health: LED risks highlighted Issues relating to the effects on health and well-being of artificial light are discussed in three recent publications; including one that says the blue-light component in white LEDs causes toxic stress to the retina. A Warner Media Company. One of the main concerns with LED lights relates to red LED lights, one of the oldest varieties still on the market. Doctors issue warning about LED streetlights. Children and teenagers, whose eyes do not fully filter blue light, are particularly sensitive to the harms of cold blue light, the French authority noted. Ideally, use bulbs with an M/P ratio of 0.4 or lower to minimize blue light exposure. Published Choose a bulb with a color temperature of 2700K or lower, preferably 2400K. “Recent large surveys found that brighter residential nighttime lighting is associated with reduced sleep times, dissatisfaction with sleep quality, excessive sleepiness, impaired daytime functioning and obesity,” the AMA wrote in their official policy statement. Harvard researchers and their colleagues conducted an experiment comparing the effects of 6.5 hours of exposure to blue light to exposure to green light of comparable brightness. Blue light like that from smartphones linked to some cancers, study finds. “There are blue light photoreceptors in the retina that directly communicate with the brain circadian clock,” Tosini, who was not involved in the ANSES report, wrote in an email. Exposure to LED light with a blue peak in its emission spectrum may have a harmful effect on our health because the blue light suppresses the production of melatonin. … © 2020 Cable News Network. Do LED lights hurt your eyes? How is full spectrum lighting beneficial, and how is it defined? Ultimately, ANSES believes the recommended maximum limit on short-term exposure to blue light should be revised downward, even if most people would only rarely be able to meet that level.

Today, LEDs are used for domestic purposes as well as industrial and commercial ones. The DOE (Department of Energy) has determined that LED lighting is no more harmful than other light sources and that there is nothing to prevent the usage of LED … Side effects of toxicity from AGA include respiratory, kidney, and reproductive issues in laboratory studies. Sign up here to get The Results Are In with Dr. Sanjay Gupta every Tuesday from the CNN Health team. What is flicker-free lighting? Harmful effects of LED lights. Age-related macular degeneration, a leading cause of vision loss among people over 50, causes damage to the macula, a small spot near the center of the retina that’s needed for sharp central vision. Blue light waves are more likely to cause harm to the retina among people who are prone to macular issues due to aging, environment, genetics or health habits, Roberts says. Effects of LED Grow Lights on Human Health The major contraindications for the use of light therapy are diseases that involve the retina of the eye (such as diabetes) and the use of photosensitizing medications (i.e.lithium, melatonin, phenothiazine antipsychotics and certain antibiotics). Tosini noted that scientists are convinced that exposure to LED blue light in the range of 470 to 480 nanometers for a short to medium period (days to weeks) should not significantly increase the risk of eye disease, but the same is not necessarily true for long-term exposure (months to years). LEDs or light-emitting diodes consist of a semiconductor chip positioned on a reflective surface; when electricity runs through the semiconductor, light is produced. During the light cycle, spend as less time as possible under the LED lights in your grow tent.
