The AMA says that life-long exposure of the retina and lens to blue peaks from LEDs can increase the risk of cataract and age-related macular degeneration. Studies also reveal that light emitted by LEDs can cause retinal changes, if there is high exposure for even a short period of time.

The risk depends on what type of bulb you are dealing with. Compact fluorescent lights contain a small amount of mercury, which can be toxic if it enters your body (see References 1). LED lights have been found to contain arsenic and lead, also at very low but potentially toxic levels (see References 2).

Almost 60% of adult Americans have adopted this habit and replaced their alarm clocks with digital technology. This habit however, can cause significant damage to your eyes. According to the American Macular Degeneration Foundation, direct exposure to the blue light emitted by LED devices can really damage the retina.

In a study published in the Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, researchers concluded that blue and white LED lighting is the most harmful to wildlife, particularly animals such as sea turtles and insects, while green, amber and yellow are more favorable.

LED (light-emitting diode) is a type of bulb that produces light using a narrow band of wavelengths. LED lighting is more energy efficient than CFL bulbs, as well as all other types of fluorescent lighting. LED bulbs produce a unique color of light that is very similar to the natural light of the sun.

Light-emitting diodes (LEDs) transform most of the energy that they consume into visible light rather than heat. Thanks to this efficient use of energy, LEDs reduce electricity consumption by 85 per cent compared to incandescent lights and 40 per cent compared to fluorescent lamps.

The short time under LED lamps, even for frequent visitors, isn't enough to increase the risk of skin cancer. ... This doesn't completely rule out the fact that gel manicures over time can lead to skin cancer or issues, but the potential damage caused by a gel manicure is so small that it's almost impossible to detect.

Most LEDs do not contain harmful substances like CFLs, so they can be disposed of like regular incandescent bulbs. ... Recycling LEDs ensures that the valuable materials in your old bulbs can be re-used. If you wish to recycle your LEDs, keep reading to learn more about our online recycling program.

Eye safety is an issue, but usually not from light in the fiber. However, fiber optics installation is not without risks. Optical sources used in fiber optics, especially LEDs used in premises networks, are of much lower power levels than used for laser surgery or cutting materials.

A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons.

LED light therapy is now used by some aestheticians to help regenerate the skin from aging. It's also used for acne. Your healthcare provider uses red or blue light frequencies based on the skincare concern. Red is primarily used for anti-aging, while blue is used for acne treatment.
