Glaucoma, a leading cause of irreversible blindness, is characterized by the progressive
loss of retinal ganglion cells (RGCs) and subsequent visual field defects. RGCs, as the final …

In the early 20th century, reading researchers expressed optimism that scientific study of
reading would improve the legibility of typefaces. Font-making was, however, complex …

Visual acuity is commonly assumed to be determined by the eye optics and spatial sampling
in the retina. Unlike a camera, however, the eyes are never stationary during the acquisition …

Crowding is the substantial interference of neighboring items on target identification.
Crowding with letter stimuli has been studied primarily in the visual periphery, with …

Crowding is the failure to recognize an object due to surrounding clutter. Our visual
crowding survey measured 13 crowding distances (or “critical spacings”) twice in each of 50 …

Certain font features (eg, letter width) can change the amount of space occupied by text in
published works. Font styles/features are also known to affect reading eye movements (EM); …

Purpose: The Bayesian adaptive quick contrast sensitivity function (qCSF) method with a 10-
letter identification task provides an efficient CSF assessment. However, large populations …

Visual crowding, the phenomenon in which the ability to distinguish objects is hindered in
cluttered environments, has critical implications for various ophthalmic and neurological …

Peripheral letter recognition is fundamentally limited not by the visibility of letters but by the
spacing between them, ie,'crowding'. Crowding imposes a significant constraint on reading …

Posterior cortical atrophy (PCA) is the canonical “visual dementia,” with affected individuals
experiencing a progressive disintegration of their visual world owing to dysfunction and …
