Which of the following is not related when calculating the sagittal depth in an uncut lens?

When calculating the sagittal depth of an uncut lens, the parameters considered include the center thickness, lens diameter, and radius of curvature. Center thickness directly influences the overall thickness and curvature of the lens, affecting how light passes through it. The lens diameter is crucial because it determines the overall shape and surface area of the lens, which can impact its optical properties. The radius of curvature is fundamental as it defines the curvature of the lens surfaces, determining how light is refracted.

Lens tint, on the other hand, does not play a role in calculating sagittal depth. Tint affects the color and light transmission of the lens but does not impact its physical dimensions or the geometric parameters that govern sagittal depth calculations. Therefore, it is disconnected from the mathematical assessment of how deep the lens will sit within a frame. This focus on curvature, thickness, and diameter is essential for understanding how a lens will fit and function optically, whereas tint is more related to aesthetic and visual comfort aspects rather than geometry.
