Answers:
If you're talking about VISUAL ACUITY, 20/20 (in feet) or 6/6 (in meters) is the normal visual acuity. The units are not usually placed beside the numerals since the measure of visual acuity is a ratio and thus there is no need for units.
If you're talking about normal VISUAL FIELD (which I don't think you mean) this is a completely different concept. VISUAL FIELD is usually measured with an automated visual field perimeter.
