What do you call those posters eye doctors use to test your eyesight?
2You should keep inflamatory politics out of questions about English - surely this is not the only example you could find of such a chart. The "humour" is not appreciated here. (I've submitted an edit with a more neutral example, without affecting the nature of your question)– GrismarOct 27, 2022 at 0:40
@Grismar I couldn't google it since I didn't know what it's called, but I saw this meme– Sergey ZolotarevOct 27, 2022 at 1:35
@Grismar by the way, your picture is of a different chart (with a different name) so strictly speaking you charged the question– Sergey ZolotarevOct 27, 2022 at 2:22
4I put "posters eye doctors use to test your eyesight" into google and found it. Please try harder– gotube ♦Oct 27, 2022 at 3:01
These are called 'Snellen charts', or more generally an 'eye chart'.
