Apparatus and methods are provided for reducing or eliminating the
progression of myopia, including a lens having an intentionally created
aberration pattern for reducing or eliminating the progression of myopia.
The aberration pattern may comprise a positive spherical aberration that
produces a wavefront error in which the paracentral wavefront is disposed
in front of the retina, thereby producing a signal that counters axial
length growth of the eye and preventing the progression of myopia.
