Bili light

A bili light[1][2] is a light therapy tool to treat newborn jaundice (hyperbilirubinemia). High levels of bilirubin can cause brain damage (kernicterus), leading to cerebral palsy, auditory neuropathy, gaze abnormalities and dental enamel hypoplasia. The therapy uses a blue light (420–470 nm) that converts bilirubin into a form that can be excreted in the urine and feces. Soft goggles are put on the child to reduce eye damage from the high intensity light.
