Feasibility and accuracy of school‐led vision screening in primary and secondary school students within the United Kingdom

Optometry and Vision Science, Volume 103, Issue 2, February 2026.
ABSTRACT Purpose Vision screening occurs once in United Kingdom (UK) children on school entry, but has recently been withdrawn in some areas. Consequently, significant refractive error and/or vision problems may go undetected. School‐led vision checking, where school staff assess vision, is increasingly advocated by the International Agency for the ...

Attention to text and pictures during storybook reading in preschool children with moderate hyperopia

Optometry and Vision Science, Volume 103, Issue 2, February 2026.
ABSTRACT Purpose Uncorrected, moderate hyperopia has been associated with poor emergent literacy skills. However, the eye movements of preschoolers have not yet been used to determine how well young, hyperopic children attend to text and pictures during storybook reading compared to emmetropic children.

Reflex maintenance of vergence eye alignment to small natural images is at risk for adults and young children

Optometry and Vision Science, Volume 103, Issue 2, February 2026.
ABSTRACT Purpose Typical human adults make reflex eye movements and computations to support stable binocular vision in milliseconds. The current project was designed to determine the impact of visual field extent on reflex vergence performance of adults and six‐ to eight‐year‐old children for images of natural scenes. Methods Twenty‐two typical adults (

Variant myopia: A new presentation?

Indian Journal of Ophthalmology, 2018
Purpose: Variant myopia (VM) presents as a discrepancy of >1 diopter (D) between subjective and objective refraction, without the presence of any accommodative dysfunction. The purpose of this study is to create a clinical profile of VM.

Relative peripheral refraction across 4 meridians after orthokeratology and LASIK surgery [PDF]

, 2018
Background: To characterize the axial and off-axis refraction across four meridians of the retina in myopic eyes before and after Orthokeratology (OK) and LASIK surgery. Methods: Sixty right eyes with a spherical equivalent (M) between − 0.75 to − 5.25

Light distortion and spherical aberration for the accommodating and nonaccommodating eye [PDF]

, 2016
To evaluate how different amounts of induced spherical aberration (SA) affect the light distortion (LD) phenomena, tests were performed using an experimental device to measure the distortion (haloes, glare, and so on) of a point source. To simulate the
