Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
LED lighting, digital screens, and fluorescent bulbs are examples of common artificial blue light sources. [7] [6] LED lighting is widely used due to its durability and energy efficiency. [2] It emits more blue light than traditional incandescent bulbs, potentially impacting the quality of sleep and eye health if used excessively at night. [2] [8]
RELATED: What your eyes say about your health "Since patients oftentimes require multiple treatments and overexposure to this, light can be potentially dangerous to your vision," she continued.
However, certain chromotherapy procedures require the individual to place the lamps near their eyes, which is not the recommended use for these lights and may alter the exposure duration to a level that can cause risk of retinal damage. With no consensus or regulation regarding how these products are to be used and whether eyewear is required ...
Fluorescent light bulbs and tubes internally produce ultraviolet light. Normally this is converted to visible light by the phosphor film inside a protective coating. When the film is cracked by mishandling or faulty manufacturing then UV may escape at levels that could cause sunburn or even skin cancer. [53] [54]

Light-emitting diode therapy (LEDT) is an therapeutic approach using different wavelengths of LED lights to treat disease. (The diagram is a blue light therapy, 415 nm wavelength) Light-emitting diode therapy (LEDT) is a clinical approach that applies different wavelengths of light to cure diseases or conditions with skin-safe lights.
