Optometric Data Characteristics of Male Prison Inmates

Color vision screening without the use of technical equipment: Scale development and cross-validation

“…Ederer (1983) has suggested that the task of conducting numerous examinations, day after day, of subjects who fell mostly in the normal, disease-free range was an inadequate challenge to hold the interest of the ophthalmologists. The alternative to general population surveys has been the collection of visual-status data from large, relatively "static" or "captive" samples, such as from schools, hospitals, prisons, or military settings, where sensory screening equipment and trained personnel are more readily available (e.g., Meyers, 1981;Pearce, Reed, & Hofstetter, 1972;Sorsby, Sheridan, & Leary, 1960). Unfortunately, the selectivity inherent in such an approach severely limits the generalizability of the obtained results, and prevents the emergence of a valid picture of the distribution of visual function in the population at large.…”
