At doctors in park slope, killing time waiting. Just weighed myself six times and checked my vision (is there something better than 20/20?)
20/10 - do you know how the visual accuity scale works? Let me briefly explain:
“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 a person with standard VA would be able to distinguish them—the distance at which their separation angle is 1 arc minute. The metric equivalent is 6/6 vision where the distance is 6 meters. Twenty feet is essentially infinity from an optical perspective (the difference in optical power required to focus at 20 feet versus infinity is only 0.164 diopters). For that reason, 20/20 vision can be considered nominal performance for human distance vision; 20/40 vision can be considered half that acuity for distance vision and 20/10 vision would be twice normal acuity.” - (thanks to wikipedia, I tried typing out this but my explanation was terrible)
