Wideband enhancement was implemented by detecting visually relevant edge and bar
features in an image to produce a bipolar contour map. The addition of these contours to the …

Purpose: To use the revised model eye to observe and compare how the world is perceived
by patients with monofocal intraocular lens (IOL), Eyhance, bifocal IOL, and Symfony, and …

Purpose: To better understand the striking overaccommodation that is triggered at
wavelengths below 430 nm (below referred to as OAB). Methods: Fourteen students served …

Although blur adaptation in myopia has been investigated, knowledge regarding its effect on
blur sensitivity remains unknown. In the present study, changes in three blur thresholds (ie …

PURPOSE We investigated the effect of retinal illuminance on the amplitude of
accommodation while the pupil of the eye remained constant. METHODS The amplitudes of …

Electronic displays and computer systems offer numerous advantages for clinical vision
testing. Laboratory and clinical measurements of various functions and in particular of (letter) …

Eyes with the corneal ectasia keratoconus have performed better than expected (eg visual
acuity) given their elevated levels of higher-order aberrations that cause rotationally …

An imaging lens structure and method of imaging are presented. The imaging lens structure
comprising a lens region defining an effective aperture of the lens structure. The lens region …

Purpose: In this study we investigated in observers with low myopia:(i) the pattern of lateral
interactions between stimuli activating early cortical analyzers and its modulation by …

The human visual system is tasked with recovering the different physical sources of optical
structure that generate our retinal images. Separate research has focused on understanding …
