Corrective Lens Equation for Nearsightedness
The corrective lens equation for nearsightedness relates the far distance for a person to the necessary lens power to correct it.
The reciprocal of the far point for nearsighted vision is directly proportional to the lens power or the spherical component of a lens prescription.
