Acuity16

• The aspects of human vision which develop following birth include visual acuity, tracking, color perception, depth perception, and object recognition. (wikipedia.org)
• The major components of the visual system can be broken up into visual acuity, depth perception, color sensitivity, and light sensitivity. (wikipedia.org)
• Visual acuity, the sharpness of the eye to fine detail, is a major component of a human's visual system. (wikipedia.org)
• Visual acuity in newborns is very limited as well compared to adults - being 12 to 25 times worse than that of a normal adult. (wikipedia.org)
• By two months, visual acuity improves to 6/45 (20/150). (wikipedia.org)
• One major method used to measure visual acuity during infancy is by testing an infant's sensitivity to visual details such as a set of black strip lines in a pictorial image. (wikipedia.org)
• Therefore, by measuring the width of the strips and their distance from an infant's eye, visual acuity can be estimated, with detection of finer strips indicating better acuity. (wikipedia.org)
• In addition to having less binocular vision than humans, dogs also have less visual acuity. (stoneybrookvets.com)
• Certain breeds have better visual acuity. (stoneybrookvets.com)
