Abstract
An ophthalmic lens includes spherical aberration in an amount that accounts for spherical aberration introduced into the lens during the manufacturing process and/or spherical aberration differences in the manufactured lens measured off of the eye and measured on the eye. The result is a lens-and-eye optical system is free or substantially free of spherical aberration, i.e., having only negligible spherical aberration. Because the optical system is free or substantially free of spherical aberration, there is no or only negligible coma induced by the normal misalignment of the lens optical axis and the eye's primary line of sight. The result is a lens-and-eye optical system that provides enhanced optical performance and visual quality. Also disclosed are methods of designing and manufacturing lenses with spherical aberration adjustments to account for manufacturing process changes and off-eye to on-eye differences.
