SPECTRAL SENSITIVITY OF SMALL RETINAL AREAS.
Abstract
Experiments evaluating the significance of spherical and chromatic aberration in the degradation of human retinal images were performed. It was found that these defects were not primary causes for the failure of the eye to perform as well as a theoretically ideal optical system. The most significant defect of the eye is, in all probability, irregular variation in dioptric power over the plane of the pupil. Measurements of the amount of light reflected through different parts of the pupil revealed that more light is reflected through the center of the pupil than near its margin. This result is analogous to the psychophysical Stiles-Crawford effect and may bear some causal relation to it. (Author)
