In my early childhood, I was taken to an oculist. As my parents suggested, I was prescribed glasses. And no one knew that I just didn’t know the alphabet.

How did you pick up the glasses? Or when you were put on -14 diopters, did you immediately recall Z and B?
____________

1) To check the visual acuity in children use a table with silhouettes (animals, plants, household items, etc.) Didn’t he swallow either?
2) Sivtsev table in the right part consists of gaps in circles. I don’t know where the left is?
3) At the "minus" the doctor looks at the retina and the lens.

So either someone is lying, or the doctor is not the doctor.
