Retinoscopy was performed on animals with different sized eyes, all of whom appeared hypermetropic. The data were well fitted by an equation of the form y = kx-2 where y is refractive error in diopters, and x is the corneo-retinal length of the eye. Apparent hypermetropia may be due to the reflection from the inner surface of the retins.
