| acuity | <ophthalmology> The clarity or clearness, especially of the vision or hearing. Origin: L. Acuitas = sharpness (18 Nov 1997) |

| absolute intensity threshold acuity | The minimal light that can be seen. (05 Mar 2000) |
|---|---|
| Vernier acuity | The detection of displacement of a portion of a line. (05 Mar 2000) |
| visibility acuity | The recognition of an object on a background of different character. (05 Mar 2000) |
| visual acuity | <microscopy> The ability to detect fine details or small distances with the eye. Visual acuity can vary substantially depending on the definition used and method of measurement chosen. Under favourable conditions, the resolution of the human eye or ability to distinguish the twoness of adjoining lines, is about I minute of arc while the threshold delectability, or the detection of misaligned steps in a line (which is also a form of visual acuity), can be as low as a fraction of a second of arc. (05 Aug 1998) |
| resolution acuity | The detection of a target having two or more parts, often measured by using the Snellen test types; indicated by two numbers: the first represents the distance at which an individual sees the test types (usually 6 meters or 20 feet), and the second, the distance at which the test types subtend an angle of 5 minutes; e.g., vision of 6/9 indicates a test distance of 6 meters and recognition of symbols which subtend an angle of 5 minutes at a distance of 9 meters. Synonym: visual acuity. (05 Mar 2000) |
| spatial acuity | The detection of the shape of a test object; e.g., perceiving polygons of the same size but with different numbers of sides. (05 Mar 2000) |
| stereoscopic acuity | The detection of differences in distance by superimposition of slightly different retinal images into a single image to the brain. (05 Mar 2000) |
| acuity |
sharpness of vision; the visual ability to resolve fine detail (usually measured by a Snellen chart) acuteness: a quick and penetrating intelligence; "he argued with great acuteness"; "I admired the keenness of his mind"
