How blind are you? How do you measure that?

by Anonymous 3 years ago

There are professionals who measure the extent if blindness.

If you and the professional share the same blindness then their test would fail to detect it

You'd have to share that blindness (whatever that even means) with *every* professional involved in testing blindness.

If they were all blind in that same way then you would never know.

None of this means that it's hard to measure blindness. *What you're really saying is* "there is some non-zero chance that everyone involved in testing and measuring blindness shares some as yet unknown blindness that impacts the measurement of blindness."

Consider it another way. Assuming that you are blind to X. And so is everybody you know. How would you know that you are blind to X?

That's just a restatement of what I wrote above. Except you turn the "non-zero chance" into a 100% chance.

Just answer the question. If you dare.

I have partial blindness in one eye. I know the exact percentage of my field of view is missing and am completely blind in those areas. I can also map it. So very measurable

How can you tell that you are not blind in ways that you do not know about?

by Anonymous 3 years ago

I disagree with your premise. It does not contain any words suggestion blindness I don't know about. Everything is relative.

Then what are eye exams

It's a way of comparing your vision with other people's vision. It will not address a shared blindness, obviously.

>It will not address a shared blindness, obviously. What are you talking about?

The factors that contribute to eyesight are measurable and not dependent on the optometrist's eyesight or strictly compared to an average like the "20/20" reference. There is no shared blindness in this case, but I think your idea could apply to other concepts.

In the field of ditch-digging we call that a "metaphor".
