Patients admitted for general medical care to a North London Hospital were screened using a pinhole disc in conjunction with their usual visual aid. One third of the group showed significant improvement in visual acuity, suggesting a change in refractive correction was necessary. These people were not more likely to have had less recent eye examinations or to complain of poor vision. They were more likely to be over 50 years old, have poor mobility, to have no idea of cost of change in refractive correction and to subjectively note improvement in vision with pinhole disc.

“…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.…”

Large-scale normative samples of data dealing with visual function and their relationships to individual difference variables are relatively scarce. This scarcity is, in part, due to the fact that data collection usually requires individual testing and the use oftechnical equipment and trained personnel rather than simple survey instruments. Using a sample of 175 individuals, we developed a self-report behavioral inventory, suitable for group testing or survey administration, to assess color vision, and validated it against laboratory tests. The inventory was then cross-validated in a separate sample of 596 subjects. The resultant brief 10-item scale was shown to be a valid and reliable predictor of color-vision deficit. Hit-and miss-rate tables were developed, and these are presented to allow investigators to select classification criteria appropriate for their purposes.

Visual screening without the use of technical equipment: preliminary development of a behaviorally validated questionnaire

The collection of epidemiological data pertaining to visual status usually requires individual testing and the use of technical equipment and trained personnel. To expedite such screening a self-report inventory, which validly predicted laboratory or clinical testing, but in a format suitable for group testing and administration by nontechnically trained staff, would be useful. This paper demonstrates the feasibility of such a screening technique. A preliminary inventory was validated against laboratory tests for acuity, color vision, and binocular function and was shown to be capable of ascertaining visual capacities and predicting visual deficits on these dimensions.
