    Might depend on the material. I have -3.5dpt on both sides and my glasses have half the width and glare. Or are those some random units again?

      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.

        Just looked in the mirror… Checks out! :)

        Thanks for the explanation. And yeah, on the op picture you can’t see any of that clearly, so he needs to have serious practice for that statement.

    You might have phrased this a lot better by keeping your stupid mouth shut. Take that as general advice.

        Look, I was a bit slow understanding a joke, so were 90% here. I got it and made another joke about it, that 90% here did not get because they were busy voting the “evil guy” down and making spiteful comments about somebody seemingly not the sharpest knive in the drawer. I got the joke. Took me three minutes. You, OTOH, will be the small minded, cowardish piece of shit that you are for all your life. Your mentality attacking anonymously out of the crowd, looking for a “victim” that momentarilly has no lobby is what we see from people like the ICE. I’ve got a pretty wife I have been married to for more than two decades, she’s got more character under her toenail than you’ll have all your life. So I still might “die alone”, right, asshole. But I still prefer it to living a life like yours.
