I have experience with both keystone and ergo vision. The keystone I use at the moment has a software which is quite user friendly and it issued a result with a Pass or Fail. The problem I find is that even the slightest 'wrong' response brings on a FAIL in big bold letters. Our OH physician says to ignore certain results as its going beyond the scope of the exercise but I have my doubt how that would look in a law court. The Ergovision Essilor is what I used about six years ago. It is a state of the art piece of equipment where the client sits at a machine which gives synthesized verbal simple instructions like ' If you see an r press the button' etc. it then issues a result like a paper from a cash register but does not show pass or fail so it's up to OH practitioner to interpret and that was not so difficult either but there was a little problem as English is not our first lI am now about to recommend to a new company and am finding it hard to decide. Hope this is helpful and look forward to getting more info on the subject.
