This image depicts a vintage Bausch & Lomb advertisement

Print titled "Alhazen -- 965-1038 A.D. -- Studied the refraction of light and disputed the ancient theory that visual rays emanated from the eye.". 

• The print features an illustration of Alhazen, a prominent Arab scientist, demonstrating optical principles related to the refraction of light. 

• It was produced by Bausch & Lomb Optical Co., a leading optical institution, and likely intended for display in optometrist offices during the 1930's as part of a set of educational advertisements. 

• The artwork highlights Alhazen's significant contributions to the field of optics, particularly his work on light refraction and his challenge to the earlier theory that visual rays originated from the eye. 

The print serves as a historical and educational piece, connecting the legacy of optical science with Bausch & Lomb's products and services. 

I have 2 other prints from this series available separately.
