In the 7th century, Greek physician Paulus Aeginta used a mask which had eye holes in it forcing the crossed eye to straighten out.

In the early 20th century, American opthalmologist, William H. Bates commented after 30 years of research: "The theory that poor vision is unavoidable does not fit the observed facts... I have seen many cases in which errors of refraction spontaneously recovered or changed form." Bates further believed that stress can adversely affect the visual system. To indluce releaxation, he advocated covering the eyes and swinging the body. He devised exercises to improve eye movements and help sharpen acuity. Through his research and the continued research of his followers, the field of behavioral optometry was born.
