William Horatio Bates (1860-1931) first published his treatise, The Cure of Imperfect Sight by Treatment Without Glasses (title page), also known as Perfect Sight Without Glasses (cover), in 1920. In 1943, Dr. Bates's wife Emily Bates had an abridged version of the book published under the title Better Eyesight Without Glasses. That book, which is still in print (by Henry Holt), omitted many experimental details, most scholarly references, and all photographs. It also omitted references to the supposed safety of looking directly at the sun (an omission that is repeated in this electronic version). In 1978, after the copyright on the original edition had expired, Health Research Books began to sell reprints, which are still available.
