Abstract

A study of the Dioptron automatic refraction machine reveals a good reproducibility of the results obtained by the machine. In a comparison with retinoscopy and subjective refraction, the spherical components were well correlated while the cylindrical power was less well related. The rejection rate of the machine was high and its usefulness in refraction is discussed.
