  • 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.













  • Clarity can also be achieved with a 4k panel. Once your panel gets over 600ppi it’s gonna blow an eink screen out of the water at its own game. Those phones were barely ever made only Sony even tried. Probably due to battery life, or maybe noone realized what they do to the reading experience.

    Either way we’re gonna improve battery life and maybe even get microled before eink ever gets competitive with emissive screens. Someone is bound to rediscover that you never truly needed eink for comfortable reading, just a significant increase in resolution.
