единица (о зрении Normal visual acuity is commonly referred to as 20/20 vision (even though acuity in normally sighted people is generally higher), the metric equivalent of which is 6/6 vision. At 20 feet or 6 meters, a human eye with nominal performance is able to separate contours that are approximately 1.75 mm apart. A vision of 20/40 corresponds to lower than nominal performance, a vision of 20/10 to better performance. wikipedia.org 4uzhoj) |
