Interpreting my distance acuity?!
Question: Interpreting my distance acuity?
My prescription says that the corrected distance acuity for my right eye is 6/120. Probably a very stupid question, but converting to the '20/20' system would just be by converting metres to feet (and round)? In other words, 6/120 = 20/390?
Again, sorry for the silly question - just trying to understand my prescription a little better!
