[Sense and nonsense in optometry (author's transl)].
Cylindrical glasses of a quarter diopter and less are in moste cases unnecessary, as we found in examination on 100 patients. Frontofocimeter and trial glasses were examined and found to be adequate for practical purposes. On the other hand, the execution of prescriptions was not always altogether satisfactory. To keep costs to a minimum super-perfectionism in optometry must be avoided and tinted glasses only prescribed when clearly indicated.
