Abstract

The computer method of visual acuity measurement is described in the paper. Optotypes of different size and orientation are presented to the subject who answers if he recognizes them or not. Basing on the subject's answers, recorded by computer, we construct psychometric function from which we calculate parameters describing VA. The method can be used in investigation of the accommodation or changes in overall state of the subject.
