VISUAL ACUITY Meaning and
Definition
-
Visual acuity refers to the clarity or sharpness of an individual's vision, specifically in terms of their ability to discern and identify fine details. It is a measure of how well the eye can see objects and distinguish small differences in shapes, colors, and patterns. Typically, visual acuity is determined through the usage of a standardized vision test, such as the Snellen chart, which typically measures the clarity of central vision.
Visual acuity is commonly expressed as a fraction, where the top number represents the testing distance in feet or meters, and the bottom number represents the distance at which a normal eye could identify the same size letter or object. For instance, if a person has 20/20 vision, it means that they can read at 20 feet what a person with normal vision can read at the same distance. On the other hand, a person with 20/100 vision would need to be at a distance of 20 feet to see what a person with normal vision could see at 100 feet.
Several factors can affect visual acuity, including the shape of the eye, the health of the cornea, and the presence of any eye conditions or diseases. Visual acuity is crucial for various activities, such as reading, driving, and recognizing faces, as it directly impacts one's ability to perform tasks that require clear and precise vision.
