Eye test with circles

Have you ever had to do an eye test with circles where one point is always slightly open?

If yes, did you have to name the openings (top ,right, bottom, left etc ...)?

Or did you have to show the openings with your outstretched thumb?

I had my diabetic eye test on friday,and one of the tests is following a circle as it moves around on the screen

Yes, had to indicate with my thumb

@Secret_sub

Where & why did you have to do the eye test?

I had two of them this year. One doctor said that it indicated that I had glaucoma, and the second opinion, was that the results were inconclusive. I had to press a button, every time that I saw a light flash. Is that the test that you're referring to ?

I think he's referring to an eye test chart with Landolt rings. From what I've seen these seem to be very common in the Netherlands, but less so elsewhere.

en.wikipedia.org/wiki/Landolt_C

Other designs of eye chart, such as the Monoyer chart popular in France and Belgium, do use the Landolt C together with other letters.

@Caron999 in Belgium. At an annual eye check

@Secret_sub

Were you allowed to point the openings with your outstretched index finger too?

Actually, I have had glaucoma for years, and have to see the optometrist 3 times a year. At which, many of the tests you have mentioned are performed to track the progression and eye pressure..

And were you allowed to name the openings verbally?

@Caron999
