All
It is my understanding in April 2013 the near vision acuity standard was set to Jaegar No 1 or equivalent, at not less than 30/12 in at least one eye, natural or corrected.
I have been informed that none of the keystone machines conform to the 12 inch requirement.
Can anyone advise me what types of kit are used for testing near vision at this distance of 12 inches.
