Ultraviolet (UV) light

A radiant component of sunlight, invisible to the eye, that is characterized by short wavelengths and high energy. It will damage the retina (as well as the skin) with lengthy, unprotected exposure. If you use nutritional supplementation, please consult with your personal physician and ophthalmologist as your personal health situation may require monitoring or a non-typical approach and nutritional supplements may interfere with prescribed medicines.

Ultraviolet (UV) light is part of the light/radiation that comes from the sun, with a wavelength shorter than that of visible light, but longer than soft X-rays. There are approximately three types of UV light: UVA (wavelengths of 400-315 nm), also called Long Wave or "blacklight"; UVB (wavelengths of 315-280 nm), also called Medium Wave; and UVC (wavelength less than 280 nm), also called Short Wave or "germicidal" (because it kills pathogenic organisms on exposed surfaces). To protect your eyes, it is recommended that you wear sunglasses that block all forms of UV light. This is particularly important for those who have retinal degenerative diseases, because their retinas may be more susceptible to damage or vision loss from exposure to UV light (depending on the nature of their disease).
