The phrase "acuity of vision" is correct and usable in written English.
It can be used when discussing the sharpness or clarity of one's eyesight or perception, often in a medical or metaphorical context.
Example: "The doctor noted that the patient's acuity of vision had significantly improved after the treatment."
Alternatives: "sharpness of sight" or "clarity of vision".
But sometimes acuity of vision leads him to become almost clairvoyant.
It is Mackenzie, a soulful adventurer with remarkable acuity of vision, whose presence gives Mr. Galbraith's story its narrative coherence.
When Mark talks about surfing big waves, he as often as not talks about how stress releases adrenaline, increases galvanic skin response, causes the eyes to dilate for greater acuity of vision, and causes the liver to release certain chemicals that increase endurance, certain other chemicals that decrease the perception of pain, and certain yet other chemicals that enhance fast-muscle fibres.
When he sees ichneumon wasps in a fleck of sunlight running about, searching, he harnesses language and his acuity of vision to describe the moment: "Every minute or two the wasps flip onto their sides and shudder their legs together, cleaning away the silk that spiders have strewn over the mandala".
Health could be defined theoretically in terms of certain measured values; for example, a person having normal body temperature, pulse and breathing rates, blood pressure, height, weight, acuity of vision, sensitivity of hearing, and other normal measurable characteristics might be termed healthy.
We are talking about abilities such as intuition, perception, acuity of vision, and ability to read the situation (Hostetler 2016; Kinsella 2012).
In this study, the investigators tested the visual acuity (sharpness of vision), contrast sensitivity (ability to distinguish gradations of light and dark), and color discrimination (ability to correctly identify colors) in 25 exposed and 40 unexposed members of the cohort.
In addition, we will investigate visual acuity (clearness of vision, spatial resolution of the visual processing system) using the non-invasive adapted Snellen charts (Medical Workshop, Groningen, The Netherlands), with and without visual aids.
All participants passed the color vision test and achieved the minimum criteria: acuity of 20 : 30 vision, stereoscopic visual acuity of 40 sec.arc.
This hypothesis was based on the idea that a narrow search width would better facilitate the search of close space using the fine-grained spatial acuity of foveal vision.
The hierarchical code system consists of the abbreviation of the component and the chapter number (e.g. b2 Sensory functions and pain), followed by the second level (e.g. b210 Seeing functions), the third level (e.g. b2100 Visual acuity functions) and the fourth level (e.g. b21000 Binocular acuity of distant vision).
