WebThe Schematic Eye of Gullstrand or the Reduced Eye of LeGrand, are technically based on a paraxial optical analysis. This paraxial analysis only applies to angles less than 1.0 degrees from the optical axis. However, the paraxial analytical technique is frequently used to get an estimate of the real case.
