Geometric Center Vs Optical Center at Amber Boniwell blog

Geometric Center Vs Optical Center. If we center bifocal lenses we should respect height of near segment’s edge. Knowing the advantages and disadvantages of each lens type. No, the optical center of a lens is the point on the lens axis that is unaffected by refraction, while the geometric center is the. The box centre distance (bcd) is also commonly known as the frame pd and it can be seen from the diagram in figure 1 that: We distinguish upper decentration as more critical. Key measurements include the a measurement (eye size), b measurement (vertical size), geometric center, distance between lenses, distance between centers, effective diameter, seg. Bcd, c = a/2 + d + a/2 = a + d. Gc = geometric center of lens. Each point is defined by the effect the optical system has on rays that pass through. Dbc/gcd (distance between gc/ geometric center distance) = distance between centers of each lens (frame pd) datum. The cardinal points lie on the optical axis of an optical system.
