A pair of actinotherapy goggles from the 1930’s manufactured by Solport brothers Ltd. of 44-47 Spencer Street, Goswell Road, London and patented by Portia under no: 369338.
The goggles were used for ultra violet ray treatment in the early 20th century. Ultraviolet light therapy, otherwise known as actinotherapy, was used to treat rickets, and tuberculosis of the skin (lupus vulgaris).
These folding goggles are in excellent condition. Although they look black in the photos they are actually dark green. The box is very worn and has no sides.
A quirky scientific curio.
