Lens Clock Equation at Alana Wardill blog

Lens Clock Equation. The lens clock will be the only tool available and i will have to estimate the rx. The lens clock, a pivotal tool in the optical industry, serves as an indispensable instrument for measuring the curvature of lenses with unmatched precision,. A lens clock is a mechanical dial indicator that is used to measure the dioptric power of a lens. To read a lens clock, align the measurement surface with the lens or object to be measured, and then note the measurement value where the indicator or needle points on the clock’s scale. The clinician may assess the refractive error with a retinoscope. It is a specialized version of a spherometer. It works by having two fixed pins and a movable central pin that indicates the sag of a curved surface when placed on a lens, directly reading the refractive power. Sagittal depth is converted to surface power. A lens clock measures surface power by determining the sagittal depth, s, of a surface. How do i determine the axis using only a lens clock?
