Reflective (objective) refraction differs basically from apperceptive (subjective) refraction in that it excludes conscious seeing from the measuring procedure. As a result limits can be established for the subjective acceptability of refraction values with automatic or manual refractometers. In a comparative study of 50 cases the correction values obtained with the manual refractometer PR 50 (Rodenstock) and the automatic refractometers Dioptron (Coherent Radiation) and Auto-refractor 6600 (Acuity Systems) were compared with the results of conventional subjective refraction. Criterion for this comparison was the visual acuity achieved with the correction values. In 55% of the cases the same, in some cases even better visual acuity was achieved than with subjective refraction. In the other 45% a direct comparison of the reflective and the subjective refraction values shows which component (sphere, cylinder) of the refractometer correction value leads to a lower visual acuity.
客观验光与主观验光的根本区别在于，客观验光在测量过程中不涉及有意识的视觉感知。因此，使用自动或手动验光仪时，可以确定验光值主观可接受性的限度。在一项对50例患者的对比研究中，将手动验光仪PR 50（罗敦司得）、自动验光仪Dioptron（相干辐射公司）和自动验光仪6600（敏锐系统公司）得出的矫正值与传统主观验光的结果进行了比较。比较的标准是矫正值所达到的视力。在55%的病例中，使用矫正值获得的视力与主观验光相同，在某些情况下甚至更好。在另外45%的病例中，客观验光值与主观验光值的直接比较显示了验光仪矫正值的哪个组成部分（球镜、柱镜）会导致较低的视力。
