You're precious. Why don't you tell me what else my eye doctor has never diagnosed me with?

9 in 10 people have some affliction of astigmatism. Astigmatism is just that your eye isn’t perfectly spherical. What does your eye prescription say in the cyl and axis fields, that’s your astigmatism correction.

  'eye prescription'? Bruh. Read the comment of mine you replied to. 20/10 and 20/13 vision. I don't need prescriptions.

    That's like saying you can run a 3 minute mile so you don't have a shoe size. This whole thread is silly.

      Shoe size is an inherent byproduct of having feet of a certain dimension. A prescription has to be prescribed. If we're doing dumb analogies, it's like you're trying to insist a homeless man must have an address.

        ...Actually, that's a real problem in the financial services sector. You can't satisfy KYC requirements without an address of record. Off topic, but I'm jumping around a bit tonight.

    Aren't those numbers about your ability to focus on distance objects, though? I could totally believe the someone might have "perfect" vision that doesn't require correction, but still have a slight astigmatism that impacts their vision under certain specific scenarios such as when viewing blue LEDs in low light. I'm not necessarily saying that's what you have, but more just that to the extent your eyes have been evaluated, it was likely "yeah they look great as far as your ability to perceive the brightly lit eye chart, no need to do the more detailed analysis where we figure out the other parameters that will never be used because you're fine, bye."

  20/10 and 20/13 means much better than average good vision. It would be bad if they were e.g. 20/30. Funny that you're LARPing an eye doctor without knowing this.
  - jbluepolarbear 5y ago
    You can still have 20/10 vision with Astigmatism. I guess my years of research into astigmatism because of my own affliction and years of optics study visual effects means I’m larping. Never said I was a doctor, I’m just intimately familiar with how corneal distortion.

      I wonder why there's such a big degree in difference between the two claims.
      - jbluepolarbear 5y ago
        The 30-60% is most likely for those affected by their astigmatism. Astigmatism is when the eye isn’t a perfect sphere. Many people have very slight astigmatism and don’t require correction.
