Abstract
The present disclosure is directed to methods of tuning chromatic aberration of the eyes of a subject for the treatment of myopia. Refractive errors of an eye of the subject are assessed in the presence of one or more of red, blue, or green colored light, individually. A hybrid achromatic lens having a refractive portion and a diffractive portion is then designed, with the hybrid lens having a distribution of power varied between the refractive portion and diffractive portion. As such, the hybrid lens produces a state of chromatic aberration for the eyes of the subject capable of reducing or eliminating myopia advancement for the eyes of the subject.
