Would be good if you could include a basic explanation as to why. I didn’t know what TASS was, and thus didn’t know what you were talking about. A simple “fake false news, this is a Russian propaganda news page, OP keeps posting Russian propaganda” would have gone a long way.













I assumed he’d estimated it based on how distorted the face appears behind the glasses. I do that all the time.
At this angle it’s hard for me to do that, since I usually use the edges of the face to estimate it. negative glasses pull the line inwards, positive outwards. I can reliably tell when someone is wearing fake glasses (0 strength) for example, and probably estimate strength within 30% of the actual value.
If the image was higher res maybe I could estimate this case too. Or this professional optometrist is just a lot better at it than I am.
Strong negative glasses: (Note the faces contours in the glasses appearing well inside the faces contours around the glassed)
Fake glasses:
Positive glasses:
PS: Searching for generic terms yields 100% fake glasses, so I took a specific person I remember having strong glasses for myopia.
