Chromatic imaging properties of myopia control spectacle lenses.

Myopia progression in children can lead to ocular morbidity during adulthood. Spectacle lenses have been developed and commercialized for myopia control (MC), but their imaging properties have only been assessed under monochromatic illumination. In this study, we quantified the chromatic imaging properties (wavelengths, 450, 532 and 635 nm) of four MC lenses and a single vision lens at three retinal eccentricities (0°, 20° and 30°) along the horizontal meridian using spatial light modulation technology. Our results suggest that the design of myopia-control lenses based on simultaneous competing blurring should enhance the quality of images projected in front of the peripheral retina at long wavelengths.
