Excerpt from Eye Studies: A Series of Lessons on Vision and Visual Tests WE first prepared and published our Eye Studies serially, in the johnston Eye Echo, an optical journal edited by the author. With some exceptions, to be noted farther on, the contents of the Eye Study series, as now presented, appeared during the five years' continuance of the Echo from 1885 to 1891. The article on color-blindness we prepared first for the Eye Leghi, the Echo's successor, of which the author was, also, editor, during 1891. The lesson on Strabismus has been considerably expanded. The series has been entirely revised and enlarged. Those who read these lessons in serial form will notice a marked change in their character as now combined. Each topic, as here presented, is treated in a Single lesson. As then treated, the same topic was frequently continued in several lessons, the subject being too large to be completed in a single issue. AS a result we had twenty-eight lessons in the paper. Covering each separate subject with a single lesson, we have in the book only fourteen lessons, including the new one on color-blindness. Everything of value in 'the serial discussion has been retained, and an expansion of many points indulged in to promote greater clearness and explicitness.

The ability to see deeply affects how human beings perceive and interpret the world around them. For most people, eyesight is part of everyday communication, social activities, educational and professional pursuits, the care of others, and the maintenance of personal health, independence, and mobility. Functioning eyes and vision system can reduce an adult's risk of chronic health conditions, death, falls and injuries, social isolation, depression, and other psychological problems. In children, properly maintained eye and vision health contributes to a child's social development, academic achievement, and better health across the lifespan. The public generally recognizes its reliance on sight and fears its loss, but emphasis on eye and vision health, in general, has not been integrated into daily life to the same extent as other health promotion activities, such as teeth brushing; hand washing; physical and mental exercise; and various injury prevention behaviors. A larger population health approach is needed to engage a wide range of stakeholders in coordinated efforts that can sustain the scope of behavior change. The shaping of socioeconomic environments can eventually lead to new social norms that promote eye and vision health. Making Eye Health a Population Health Imperative: Vision for Tomorrow proposes a new population-centered framework to guide action and coordination among various, and sometimes competing, stakeholders in pursuit of improved eye and vision health and health equity in the United States. Building on the momentum of previous public health efforts, this report also introduces a model for action that highlights different levels of prevention activities across a range of stakeholders and provides specific examples of how population health strategies can be translated into cohesive areas for action at federal, state, and local levels.
