The study of biological optics would be complicated enough if light only came in a single
wavelength. However, altering the wavelength (or distribution of wavelengths) of light has …

Ocular wavefront aberrations are used to describe retinal image formation in the study and
modeling of foveal and peripheral visual functions and visual development. However …

It has been known for more than 220 years that the image quality of the human eye is
significantly degraded by chromatic aberrations. Recently, it was shown experimentally that …

Detecting optical defocus at the retina is crucial for accurate accommodation and
emmetropization. However, the optical characteristics of ocular defocus are not fully …

Metasurfaces offer novel design capability of optical wavefront sha** to realize ultra-
compact flat optical components which have remarkable potential to mitigate the constraints …

Chromatic aberration, also referred to as chromatic distortion, color fringing, and
spherochromatism, is a common optical phenomenon that occurs when a lens cannot bring …

Background Ophthalmic quality of life (OQoL) has been investigated in selected parts of
general populations and in patients with ocular disease, but OQoL in unselected general …

Manipulating ocular longitudinal chromatic aberration (LCA) can enhance visual outcomes
in presbyopia-correcting multifocal intraocular lenses and serve as a powerful tool for …

Insulin signaling is crucial for maintaining cellular function and systemic homeostasis, with
its dysregulation leading to metabolic disorders in particular diabetes. While insulin analogs …

Background: Three computerized tests were designed to evaluate visual function, alertness,
and visuocognitive integration under three different lighting conditions (white, red, and blue …
