Imaging Quality and Fatigue Quantification of Ocular Optical System
IEEE Access, 2020 Human eye is a special kind of optical system, and its imaging quality and fatigue level seem susceptible to the illumination. In this study we were sought to develop a novel method to quantify ocular fatigue more accurately, and to assess the influence ...

Proteomic analysis of the bovine and human ciliary zonule [PDF]
, 2016 PURPOSE: The zonule of Zinn (ciliary zonule) is a system of fibers that centers the crystalline lens on the optical axis of the eye. Mutations in zonule components underlie syndromic conditions associated with a broad range of ocular pathologies ...

Cognitive workload affects ocular accommodation and pupillary response
Journal of Optometry, 2023 Cognitive involvement in reading causes variations in the tonus of autonomic nerve system. The aim of this study was to examine the effect of short-term cognitive load on accommodation and pupils' absolute values and temporal variability in test persons performing three different types of tasks.We aimed to show how cognitive tasks of different type and

The Cambridge Anti-myopia Study: variables associated with myopia progression [PDF]
, 2013 Purpose: To identify variables associated with myopia progression and to identify any interaction between accommodative function, myopia progression, age, and treatment effect in the Cambridge Anti-Myopia Study. Methods: Contact lenses were used

Ocular Autonomic Nervous System: An Update from Anatomy to Physiological Functions
Vision, 2022 The autonomic nervous system (ANS) confers neural control of the entire body, mainly through the sympathetic and parasympathetic nerves. Several studies have observed that the physiological functions of the eye (pupil size, lens accommodation, ocular ...

Effect of accommodation on peripheral ocular aberrations
Journal of Vision, 2009 Changes in peripheral aberrations, particularly higher order aberrations, as a function of accommodation have received little attention. Wavefront aberrations were measured for the right eyes of 9 young adult emmetropes at 38 field positions in the central 42 x 32 degrees of the visual field. Subjects accommodated monocularly to targets at vergences of

Vision and Reading Difficulties Part 2: Optometric correlates of reading difficulties [PDF]
, 2009 In this second article of the series on vision and reading difficulties, the optometric factors (for example refractive error and orthoptic function) that may be associated with reading problems are discussed in detail.
