The Eyes and How to Care for Them
Here are some simple and sound rules for care of the eyes, as formulated by a recognized authority on the subject. Avoid reading and study by poor lights. Light should come from the side of the reader, and not from the back nor from the front. Do not read or study while suffering great bodily fatigue or during recovery from illness. Do not read while lying down. Do not use the eyes too long at a time for anything that requires close application, but give them occasional periods of rest. Reading and study should be done systematically. During study avoid the stooping position, or whatever tends to produce congestion of the blood in the head and face. Read with the book on a level with the eyes, or nearly so, instead of in your lap. Select well printed books. Correct imperfection in sight with proper glasses, not selected carelessly by yourself or bought from an irresponsible wandering peddler, but properly fitted by an educated optician. Avoid bad hygienic conditions and the use of alcohol and tobacco. Take sufficient exercise in the open air. Let physical culture keep pace with mental development, for imperfection in eyesight is most usually observed in those who are lacking in physical development.
