Hi guys, i was researching on internet and randomly found this forum.I would like to ask you something about ishihara's versions.Because a very short span of time ago i went to doctor for a routine eye check and made few mistakes (4 or 5) but i know i m not colour blind or deficient because 2 years ago i did ishihara too and made only 1 mistake.I told that to doctor this situation and asked for the type of test.As I heard from doctor it was ishihara 38 plate.And I know that I was tested on 24 plate 2 years ago and made only 1 mistake. I was really suprised that why it had happened?Can anyone tell me what is the difference between 2 version?Arent the plates same in both 24 and 38?I mean arent the plates of 24 choosen from 38? By the way I m not a pilot or not trying to become.Thanks for the interests
