A reference value above which visual acuity is considered normal is called 6/6 vision, the USC equivalent of which is 20/20 vision: At 6 metres or 20 feet, a human eye with that performance is able to separate contours that are approximately 1.75 mm apart. [9] Vision of 6/12 corresponds to lower performance, while vision of 6/3 to better ...
Legally blind indicates that a person has less than 20/200 vision in the better eye after best correction (contact lenses or glasses), or a field of vision of less than 20 degrees in the better eye. Totally blind students learn via braille or other non-visual media.
Contoura Vision is the only technology where consistent success beyond 20/20 vision has been achieved in the majority of patients. More than 40% of the patients that were evaluated were able to read one line on the visual acuity chart more than a person with 20/20 vision, and 13.5% could read two additional lines.

Within a few months, almost all patients went from having an average of 20/1290 vision to 20/20 vision! Even more amazing, the amount of time between the trauma and the treatment didn't seem to ...

In the term "20/20 vision" the numerator refers to the distance in feet from which a person can reliably distinguish a pair of objects. The denominator is the distance from which an 'average' person would be able to distinguish —the distance at which their separation angle is 1 arc minute .
This is different from visual acuity, which refers to how clearly a person sees (for example "20/20 vision"). A person can have problems with visual perceptual processing even if they have 20/20 vision. The resulting perception is also known as vision, sight, or eyesight (adjectives visual, optical, and ocular, respectively).
