using a book of color vision plates or pages, this test screens for acquired and/or hereditary color visual defects. 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:

The measurement of the acuteness or sharpness of vision is: color vision test-ultrasonography-tonometry-visual acuity. Visual acuity. Surgical destruction of the crystalline lens is called: phacolysis-phacosclerosis-presbyopia-orthoptics.
Phacolysis. In the term phacoemulsification, the combining form phac/o means: pupil-iris.

The need for precision in visual acuity assessment for low vision research led to the design of the Bailey–Lovie letter chart. This paper describes the decisions behind the design principles used and how the logarithmic progression of sizes led to the development of the logMAR designation of visual acuity and the improved sensitivity gained from letter-by-letter by: Test-Types for Determination of the Acuteness of Vision [Probebuchstaben zur Betimmung der Sehscharfe].
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.
