Ishiara test
Be careful, I just tested the electronic Ishiara with 100% success, altough, in a former life as a Merchant marine officer, I experienced trouble when passing the paper version. bear in mind, that most people are not rejected for uncorrect reading of numerals but for reading numerals where you shouldn't see any. As you will note the plates which are not showing a numeralshow x. On the official Ishiara plates, the x is never located where the numerals are on other plates. The numerals and the x are present to assist a colour blind examiner when the plates are shown at random. If you carefully look at the location of his fingers hiding the marks, you know if you are entitled to read something or not.
I passed lantern tests( I don't know which ones) without problems as the contrast is much greater than on the paper plate.
My twopences worth.
