Abstract
A system for measuring the eye comprising a light source which sends a narrow collimated beam of light , to reflect from a beam splitter . The beam of light enters the eye through the pupil where it is focused to a point on the retina . The light is reflected from the retina where it passes through a series of relay lenses . The light then passes through one or more reticles . A CCD camera records the shadow pattern formed by reticles . The shadow pattern is digitized into a computer and algorithms are created to calculate the distortions. As a result of the above steps being performed, the refractive power of the eye can be measured at many points, simultaneously.
