The plasticity of near space: evidence for contraction [PDF]

open access: yes, 2009
The distinction between near space and the space farther away has been well established, as has the relation of this distinction to arm length. Recent studies provide evidence for the plasticity of near space, showing that it is possible to expand its ...

The steady-state visual evoked potential in vision research : a review [PDF]

open access: yes, 2015
Periodic visual stimulation and analysis of the resulting steady-state visual evoked potentials were first introduced over 80 years ago as a means to study visual sensation and perception. From the first single-channel recording of responses to modulated

The visual outcome after cataract surgery with multifocal intraocular lenses and monofocal intraocular lenses at tertiary care hospital: A prospective observational study

open access: yesIndian Journal of Health Sciences and Biomedical Research KLEU, 2017
Background: The crystalline lens is part of the optical system of the eye that focuses rays of light on the retina. Apart from contributing to the optical power of the eye as a whole, the crystalline lens can dynamically change the optical power of the ...

Evaluation of an Eye-Tracking-Based Method for Assessing the Visual Performance with Progressive Lens Designs

open access: yesApplied Sciences, 2023
Due to the lack of sensitivity of visual acuity (VA) measurement to quantify differences in visual performance between progressive power lenses (PPLs), in this study, we propose and evaluate an eye-tracking-based method to assess visual performance when ...

Binocular vision with null disparity disrupts the effects of extra-retinal signals

open access: yes, 2009
We studied a novel phenomenon indicating that the integration of extra-retinal information and the optic flow is a necessary but not sufficient condition for slant constancy during active head motion; congruency between monocular and binocular cues to ...

Effectiveness of low-dose topical atropine in preventing the progression of myopia – A prospective interventional cohort study in pediatric patients

open access: yesThe Pan-American Journal of Ophthalmology
Background: Myopia is a very common pathological condition in the pediatric age group which can lead to devastating complications if not treated early. Recent studies support the use of atropine drops of various concentrations to prevent the progression ...

A comparison of visual outcomes in three different types of monofocal intraocular lenses [PDF]

open access: yesInternational Journal of Ophthalmology, 2015
AIM: To compare the visual outcomes (distance and near) in patients opting for three different types of monofocal intraocular lens (IOL) (Matrix Aurium, AcrySof single piece, and AcrySof IQ lens).

Near Vision Difficulties With Flexible Contact Lens Wear [PDF]

open access: yes, 1978
Near vision problems with flexible contact lens wear are often sited as a cause for patient failure. This near vision blur is shown to be primarily caused by distortion of the anterior contact lens surface during near fixation.
