The first is discomfort and glare. For example, “warm white” domestic LED lighting has weak phototoxicity risks, similar to traditional lighting, according to ANSES. Do LED lights hurt your eyes? In addition, a stroboscopic affect in some LED lights—provoked by tiny fluctuations in electric current—can induce "headaches, visual fatigue and a higher risk of accidents," the report said. LEDs with this light color contain a significant amount of blue light in their spectrum. Choose a bulb with a color temperature of 2700K or lower, preferably 2400K. Here’s an illuminating fact: the negative effects of using LED and blue lights at night can be both mental and physical, and they far outweigh any perceived benefits. 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. 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). Doctors issue warning about LED streetlights. 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 AMA also said that white LED lights are five times more damaging the circadian sleep rhythms than other street lamps. LEDs or light-emitting diodes consist of a semiconductor chip positioned on a reflective surface; when electricity runs through the semiconductor, light is produced. LEDs are “undergoing rapid technological and economic development as a new source of lighting. The blue light in LED lighting that is increasingly used in our homes can damage the eye’s retina while disturbing our biological and sleep rhythms, a French health authority warned in a new report.

Some scientists have indicated some negative effects of LED lighting as follows: Toxic Materials; In a study published 2010 in a journal named Environmental Science and Technology, it indicated that LEDs contain toxic material including lead, and arsenic among others. During the light cycle, spend as less time as possible under the LED lights in your grow tent. Sources of Blue Light The single greatest of blue light is sunlight but you are exposed to many other sources: Fluorescent and compact fluorescent lights Hmmm. 11:47 AM EDT, Thu May 16, 2019. ...Read More. Sunlight produces rays of blue that have higher energy than other wavelengths in the light spectrum. People with a history of skin cancer and systemic lupus erythematosus should also avoid this kind of treatment. There are growing concerns that LED lights may have a negative impact on human health. 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. Ultra-high CRI LED lighting for home, residential and hospitality applications, Color-correct, full-spectrum tungsten and daylight light sources for film, cinema and still photo use, ISO-compliant D50 and D65 light sources for graphic arts and industrial applications, Bias lighting for color-critical digital arts and on-screen applications, Natural daylight spectrum provides accurate and consistent lighting conditions for graphic arts creation, Full-spectrum white light sources for maximum yield and growth quality, Flicker-free and full-spectrum light sources for improved health, energy and circdian well-being, True 365 nm ultraviolet LED products for fluorescence and curing applications, Browse our selection of articles and interactive tools. “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. Light-emitting diodes (LED) use shortwave light, often called “cool” in color. Lead author Gianluca Tosini, professor and chief scientific research officer at Atlanta’s Morehouse School of Medicine, said blue light can indeed damage the eyes, but only if the wavelengths are below 455 nanometers and the intensity is quite high. The type of LED light you use - color temperature, CRI and the light spectrum can all affect the relative amount of blue light in a light's spectrum. Like other lighting technologies, LED grow lights must be checked for photobiological safety according to EN 62471 – the standard for photobiological safety of lamps and lamp systems. If you are directly exposed to this material on work sights or through contact with broken bulbs, it can be hazardous to your health. However, Sparrow said that, generally, sunglasses block ultraviolet light, and those “that have a yellow tint should be preferred as they will also reduce the amount of blue light that reaches the retina.”.
