摘要
An apparatus for determining spherical and cylinder components of subjective refraction of a patient's vision includes a wavefront measurement device that can produce a measure of quality of vision in a return beam from the patient's eye viewing a target through a corrective test lens in the apparatus. The corrective lenses may be varied and a plurality of measurements of quality of vision may be obtained and analyzed to determine the spherical and cylinder components. Accordingly, the eye examiner may conduct a refraction examination without a subjective response from the patient.
