METHODS First, we compared the ability of AIM-VA and ETDRS to detect defocus and
astigmatic blur in 22 normally sighted adults. Spherical and cylindrical lenses in the …

Importance Many ophthalmology appointments have been converted to telemedicine
assessments. The use of a printed vision chart for ophthalmology telemedicine …

Do individuals prefer stimuli that are ordered or disordered, simple or complex, or that strike
the right balance of order and complexity? Earlier research mainly focused on the separate …

This review presents the extent to which engagement in research and new developments in
clinical practice alike have contributed to the establishment and development of the primary …

Purpose When central vision is compromised, visually‐guided behaviour becomes
dependent on peripheral retina, often at a preferred retinal locus (PRL). Previous studies …

Recognition acuity—the minimum size of a high-contrast object that allows us to recognize it—
is limited by optical and neural elements of the eye and by processing within the visual …

In dynamic environments, a central task of the attentional system is to keep track of objects
changing their spatial location over time. In some instances, it is sufficient to track only the …

Purpose Sloan letters displayed by the Electronic Visual Acuity (EVA) system are the gold
standard for recognition acuity measurement in research settings. However, letters are not …

In clinical testing of visual acuity, it is often assumed that performance reflects sensory
abilities and observers do not exhibit strong biases for or against specific letters, but this …

Purpose: Reliable estimation of visual acuity requires that observers maintain a constant
distance from the target, but use of chin rests is not always feasible. Our aim was to quantify …
