Near Visual Acuity: Near visual acuity is a measurement of how well you can see close objects. Usually measured at about 16 inches, it is a good way to measure your ability to cope with tasks such as reading or sewing. In most cases, near visual acuity is measured with both eyes open.
A visual acuity chart is used to test distance visual acuity. It uses capital letters of different sizes to test vision in literate adults. The test is conducted at 6 metres (20 feet in USA).The test result is given as a fraction that indicates the distance in metres at which that row of the chart can be read by a normal eye.he bottom number represents the size of the letter seen. The larger the bottom number the larger the letter on the chart (E.g. 6/48 indicates a bigger letter than 6/12). Normal visual acuity is recorded as 6/6 (20/20 in USA).
