APPARATUS FOR INDICATING AN ASPHERICITY OF THE CORNEA OF AN EYE

摘要

A circular array of twelve light sources transmit light to an eye. A spherical shape of the cornea of the eye is indicated when light reflected therefrom appears to be transmitted from twelve virtual light sources disposed along a circular path within the eye. Correspondingly, an aspherical shape of the cornea is indicated when the virtual sources appear to be disposed along a circular path within the eye. The array may be disposed within a light reflecting grove which collects ambient light which ? transmitted to the eye. A reflection of the collected light appears to be a ring of light which connects the virtual sources.
