1. A method comprising improving depth of focus in a first eye only by
adding a higher order aberration (HOA) to the first eye by adding a monofocal optical device to the first eye, wherein the HOA is a longitudinal spherical aberration (LSA) and the LSA is less than or equal to 0 mm for all normalized radial distances.
