View Schematic Eye And Reduced Eye Pics. Moving2 positive refracting components closer together increases the refracting powerof the eye, e.g., moving the crystalline lens forward toward the cornea. The refractive power of this reduced schematic eye is 60.0 d, with its principal plane at the front surface of the cornea.
Oin the schematic eye , as described by gullstrand.
Schematic eyes have a uniform refractive index throughout. The refracting surface of the reduced eye is a hypothetical surface that lies midway between the principal points of the schematic eye. A diagrammatic illustration of the ideal normal eye, with constants for curvature, indices of refraction, and distances between the optical elements. Othe refracting system is expressed in terms of its cardinal points ( measured in 14.
