title: Reduced acuity and its relation to blur threshold measurements in optometric tests.
abstract: Sensitivity to blue was investigated in a group of subjects having long-standing reduction of visual acuity, and in another group of subjects whose acuity was reduced for the purpose of the study. The distributions of scores was compared with those of a previous study of subjects with normal acuity. The reduction of acuity produced a shift in both distributions, the greater shift occurring in the second group.
