ERIC ED541333: The Eyesight of School Children: Defective Vision as Related to School Environment, and Methods of Prevention and Correction. Bulletin, 1919, No. 65
This is a 1919 United States Bureau of Education bulletin, number 65, on children's eyesight and how classroom lighting, window shades and room conditions affect defective vision, written for school officials and health workers. The photographs are dim, grainy black-and-white views of classrooms with windows, shades and overhead fixtures, paired with captions that contrast poor and improved lighting, which suggests a designer could draw on them for stark, documentary imagery of interior light and shadow.
