Abstract

The spectacle values of young healthy students were determined morning and afternoon by means of phoropter and autorefractometer. In addition, keratometry was performed. When the morning and afternoon refraction values were compared the latter were found to be about 0.25 diopters lower. This effect cannot be attributed exclusively to changes in the radius of the cornea.
