Описание к видео Visual acuity Scales. Difference among 6/60, 6/36,6/24 6/12, 6/9 and 6/6?

In this video we will learn about visual acuity scales.
If we read top letter it means our VA is 6/60
2nd line means 6/36
3rd line 6/24
4th line 6/18
5th line 6/12
6th line 6/9
And last line means 6/6 which is normal visual acuity.
The numerator 6 is actually distance between patient and Snellen chart and denominator is actually the comparison between a patient and normal 6/6.patient.
