WASHINGTON--(BUSINESS WIRE)--Several scientific studies over the last 30 years have looked at the role of ultraviolet (UV) light in triggering the autoimmune disease lupus. UV light is invisible radiation from the sun and is also emitted from fluorescent lights. As many as half of the estimated 1.5 million Americans living with lupus experience abnormal light sensitivity, or “photosensitivity.” People who are photosensitive develop a skin rash as a result of unusual reaction to sunlight or artificial light containing UV rays.
