Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, neonatal jaundice, and skin wound infections.
Blue light therapy is a non-invasive treatment that uses blue wavelength range. With this type of therapy, there is no recovery time and it’s typically used for people with moderate to severe acne .
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
“Blue light therapy is most commonly used to treat sun damage and premalignant or malignant skin cancer growths,” Healthline reported. “It can be used to improve skin texture and reduce ...
Blue light is absorbed by the lens, preventing blue light from reaching the retina at the back of the eye. [12] To prevent retinal damage, the lens has to lower transparency. [ 9 ] This reaction causes visual impairment and the development of cataracts , [ 13 ] [ 14 ] a cloudy region in the lens.
Blue light therapy is an effective acne treatment and is useful for preventing early skin cancers. Here are all the facts, and the best blue light devices. Blue Light Therapy Cured My Acne, Here ...
Short-term over-exposure can cause snow blindness, which is analogous to sunburn of the cornea, or can cause solar retinopathy, which is long-lasting retinal damage and vision impairment from sungazing. [52] [53] Frequent exposure to the sun can cause yellow non-cancerous bumps on the middle part of the sclera of the eye, called pingueculae. It ...
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.
