Abstract
Contact lenses incorporating an array of non-coaxial lenslets with add power that create non-coaxial myopic defocus within the optic zone of the lens may be utilized to prevent and/or slow myopia progression. The positive, non-coaxial lenslets cover about twenty to eighty percent of the central pupil area to deliver positive foci of light in front of the retina to slow the rate of myopia progression.
