Binocular contrast discrimination needs monocular multiplicative noise. [PDF]
, 2016 The effects of signal and noise on contrast discrimination are difficult to separate because of a singularity in the signal-detection-theory model of two-alternative forced-choice contrast discrimination (Katkov, Tsodyks, & Sagi, 2006).

A geometric model of ocular accommodation
Vision Research, 2010 An exoteric geometric mechanics model of ocular accommodation is detailed to elucidate the main ideas of various ongoing modeling efforts. The present study derives solutions for the stretched state of the ocular lens as it might appear during accommodation by using simple geometric arguments and a volume constraint, rather than the more mathematically

Acceleration characteristics of human ocular accommodation
Vision Research, 2005 Position and velocity of accommodation are known to increase with stimulus magnitude, however, little is known about acceleration properties. We investigated three acceleration properties: peak acceleration, time-to-peak acceleration and total duration of acceleration to step changes in defocus.

Dynamic accommodation measurement using Purkinje reflections and machine learning
Scientific Reports, 2023 Quantifying eye movement is important for diagnosing various neurological and ocular diseases as well as AR/VR displays. We developed a simple setup for real-time dynamic gaze tracking and accommodation measurements based on Purkinje reflections, which ...

Influence of orthokeratology lenses on the state of accommodative function in children with myopia
Zaporožskij Medicinskij Žurnal, 2014 Aim. It was showed that optimal optical correction have positive effect on the accommodative apparatus of the myopic eye. Absolute and relative accommodation reserves, the nearest point of clear vision in 50 patients (100 eyes) with mild myopia was ...
