The consistency of values obtained by the automatic refractor "Dioptron" was evaluated by testing one subject repeatedly. The consistency was found so be significantly better than that given by subjective refraction. In about 20% of 140 eyes visual acuity found by the "Dioptron" - refraction was lower than that found by subjective refraction. Thus the results of the "Dioptron" should be controlled by a subjective refraction. The apparatus was also used in 15 children 5 to 12 years of age without problems.
