The need for precision in visual acuity assessment for low vision research led to the design of the Bailey–Lovie letter chart.

PW van de Weijer: Utrecht, PW Cited by: Page - The distribution of near-sightedness, chiefly in the cultivated ranks, points directly to its principal cause, viz.: tension of the eyes for near objects. Respecting this fact there can be no doubt.

"Three factors may here come under observation: 1. Pressure of the muscles on the eye-ball in strong convergence of the visual axes ; 2. Talk of best practices, teaching programs, cycles, and progressions can lull the casual observer into believing that programs on their own bring about result.

A program's success is only as powerful as the vision and determination of the teacher delivering it and the learner engaging in it. Brit. Ophthal.

Corneal topography using a computerized and digital instrument: maps the curvature of the cornea and is useful in diagnosing corneal diseases such as keratoconus and astigmatism.

But this determination to one object does not proceed from the vision of the believer, but from the vision of Him who is believed.

Thus as far as faith falls short of vision, it falls short of the knowledge which belongs to science, for science determines the intellect to one object by the vision and understanding of first principles.

Vision science, with the ultimate goal of providing a mechanistic account for how we see, has placed a great emphasis on measuring and explaining sensitivity for a wide range of target objects in a wide range of conditions.

Fechner’s book, Elemente der Psychophysik, was the beginning of the modern by: Crowding, today, can be appreciated as a key fact about how people visually recognize objects.

Object recognition has been studied intensely for a long time as a computational problem to which human visual perception provides a solution [4, 5].However, from its discovery until recently, crowding has been studied entirely outside of the research effort explicitly directed at object by: A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text.

Visual acuity (VA) commonly refers to the clarity of vision, but technically rates an examinee's ability to recognize small details with acuity is dependent on optical and neural factors, i.e., (1) the sharpness of the retinal focus within the eye, (2) the health and functioning of the retina, and (3) the sensitivity of the interpretative faculty of the : This is based off of the "Book of Readings" given by Excelsior college, along with "Why Nations Go to War" by John Stoessinger, "Understanding Global Conflicts and Cooperation" by Nye and Welch, and "War, Peace, and International Politics" by David Ziegler.

Visual acuity is a measurement of the eyes’ ability to resolve spatial detail. Within clinical settings, it has traditionally been assessed using test charts incorporating optotypes.1 In the UK, data are generally specified as an “Acuity Fraction,” although in Europe, decimal conversion is commonplace.
