Paperback. Zustand: New. Print on Demand. This book addresses methods for testing patients' visual acuity by illuminating test charts with artificial light sources to ensure consistency and accuracy. In the mid-1800s, with electric lighting still a new technology, ophthalmologists began illuminating visual test charts with gas, oil, and electric light in hopes of standardizing methodology. The author presents the deliberations of the Section on Ophthalmology of the American Medical Association on standardizing the illumination of test charts used to measure visual acuity.
