The perceived focus of an image can be strongly biased by prior adaptation to a blurred or
sharpened image. We examined whether these adaptation effects can occur for the natural …

Previous studies suggest that certain combinations of coma and astigmatism improve optical
quality over astigmatism alone. We tested these theoretical predictions on 20 patients …

The ubiquity of social vocalizations among animals provides the opportunity to identify
conserved mechanisms of auditory processing that subserve communication. Identifying …

PURPOSE: To investigate the optimal amount of spherical aberration (SA) in an intraocular
lens (IOL) to maximize optical quality. SETTING: Cullen Eye Institute, Baylor College of …

In 2001, a group of student activists at Syracuse University started an organization called the
Beyond Compliance Coordinating Committee (BCCC). The BCCC activists used disability …

Flickering lights can be uncomfortable to look at and can induce seizures in observers with
photosensitive epilepsy. However, the temporal characteristics contributing to these effects …

Previous theories of myopia development involved subtle and complex processes such as
the sensing and analyzing of chromatic aberration, spherical aberration, spatial gradient of …

We determined the degree to which change in visual acuity (VA) correlates with change in
optical quality using image-quality (IQ) metrics for both normal and keratoconic wavefront …

An imaging arrangement and method for extended the depth of focus are provided. The
imaging arrangement comprises an imaging lens having a certain affective aperture, and an …

We measured the effect of the correction of the natural aberrations of the eye by means of
adaptive optics on the subject's performance on three different visual tasks: subjective …
