Off-axis imagery through two multi-segment lenses for myopia treatment

Year: 2025

Type: article

Abstract: We used modeling to investigate the imaging characteristics of two multi-segment spectacle lenses intended to treat myopia progression. Determinations were made for the peripheral field, when the eye looks through the lens center, and for foveal vision, when the eye rotates and looks through the lens surround, including the segments. Power corrections were derived across the field and across the pupil, and image quality was determined through spot diagrams and point-spread functions. Optics were characterized by high corrections, particularly in the periphery, including considerable astigmatism and large variations across the pupil. As with another lens studied previously, obliquity of light incidence produced greater aberrations than would occur at normal incidence.
