The postcycloplegic test is one to be considered distinctly as a supplement to refraction carried out under cycloplegia, and is commonly grossly abused by the free-hand mutilation that it suffers in the hands of the careless refractionist. The value of results obtained in the test depend largely on the reliance that may be placed on the figures obtained under cycloplegia. It will be assumed, therefore, that the test is based on numerical determinations obtained by painstaking retinoscopy and a careful check-up with the trial case. The elements of uncertainty that may affect the accuracy of figures in these fundamental tests are too well known to be cited in this connection, and the refractionist must be the judge of how far subjective influences have affected objective data. It will be taken for granted, however, that a drug is used that will yield fairly consistent figures in the retinoscopy and
