The Zernike polynomials are a complete set of continuous functions orthogonal over a unit
circle. Since first developed by Zernike in 1934, they have been in widespread use in many …

Adaptive optics (AO) is a technology used to improve the performance of optical systems by
reducing the effects of optical aberrations. The direct visualization of the photoreceptor cells …

A study of optical aberrations for flat lenses based on phase discontinuities is reported. The
wave aberration function and the analytical expression of the aberrations up to the 4th order …

We propose a new type of a wavefront aberration sensor, that is, a Zernike matched
multichannel diffractive optical filter, which performs consistent filtering of phase distributions …

We describe a system which corrects dynamically for the focus of the real world surrounding
the near-eye display of the user and simultaneously the internal display for augmented …

Methods Laser capsulotomy was performed during cataract surgery with a curved contact
lens interface (CCL) or a liquid optical immersion interface (LOI). The presence of corneal …

Several intraocular lens (IOL) materials and types are currently available. Polymethyl
methacrylate IOLs used to be the gold standard, but the inability of folding limits their use to …

Purpose: This study aimed to evaluate short-term visual performance and optical quality of
three different lenslet configurations on myopia control spectacle lenses. Materials and …

The pupil responds reflexively to changes in brightness and focal distance to maintain the
smallest pupil (and thus the highest visual acuity) that still allows sufficient light to reach the …

Recent research on the legibility of digital displays has demonstrated a “positive polarity
advantage”, in which black-on-white text configurations are more legible than their negative …
