WebJan 3, 2024 · If only spherical lenses were available, would it be:-3.0 — ignore the cylinder value-2.5 — add the cylinder value-2.75 — add half the cylinder value; ... That means the spherical power describes the most divergent meridian and the cylindrical component describes the most convergent. In the minus cylinder notation, the cylinder power is a ... WebApr 5, 2024 · Because cylindrical and spherical unit vectors are not universally constant. Though their magnitude is always 1, they can have different directions at different points of consideration. So unlike the cartesian these unit vectors are not global constants. Read:Derivatives of the unit vectors in different coordinate systems.
