Child-size protective goggles for use during ultra-violet light therapy, London, England, 1930-1935
Ultraviolet light therapy or actinotherapy uses UV light. UV light kills bacteria and was used in the treatment of skin tuberculosis (lupus vulgaris) and rickets. Rickets was common in those with a vitamin D deficient diet. A lack of sunlight also contributed to the condition. High concentrations of UV light can damage the eyes, so green plastic goggles like these were worn by children undergoing treatment. UV light treatment was pioneered by Neils Ryberg Finsen (1860-1904) in 1894.
