The good news: I don’t need glasses yet.
The bad news: I got told to sit further away from the computer monitor or else. I think ‘or else’ is going to occur, because I have this urge to lean in whenever I’m playing computer games and watching films on my computer; I think it’s the effect of immersion, or maybe one required condition for immersion is me leaning in close to the screen. Either way, I’m not giving up computer games and films just so I don’t have to wear glasses some day.
So yeah, that was the 20/20 part of the test. Not really funny, exactly, but mildly interesting.
But the other part of the test was fascinating. The colour blindness test. I already knew I was colour blind, and there is in fact a great story behind that, which I’ll tell first.
I started in 2007 when I got the medical test needed for my Chinese visa (I was still in Brisbane at the time). The nurse giving me the colour blindness test laughed her head off while I kept on failing to see the numbers I should have been able to see. Everything was going according to the standard type of colour blindness until the last two pictures. I couldn’t see anything, but apparently normal colour blind people can see those last two. Me and the nurse just shrugged it off as a little weird.
Later, another significant event occured while I was studying in Beijing. In between classes me and my friends would meet in the corridor and joke around. My friend Haakon from Norway turned up wearing an interesting shirt. It was just a plain black t-shirt with some cool patterning in the shapes of circles of various green colours and some red circles too. I’m writing this from my perspective at the time, naturally.
I strongly believe that my friends were telling me the truth about what follows. They have never lied to me before. What happened was they started giggling as though I’d made an odd comment. They stared at me quizzically. And then Haakon asked me the question which gave birth to my growing suspicion of empiricism.
“You can read it, right?”
“Read what?”
There was a moment’s pause, and then my friends all broke into uproarious laughter.
“What?”
They were laughing at what was written on the t-shirt. I couldn’t read it so I didn’t realize what was funny. It was this t-shirt:

Now, my recent test:
The optometrist was cool and collected for the majority of my negative answers. But when we got to the last two, she sounded irritated. What she was about to say blew my mind and made me burst into laughter. I’m sure she didn’t like that. But I couldn’t help it; what she said ranks quite highly on my mental list of contradictory quotes which I’ve had the pleasure of hearing within my lifetime.
“Look closer. If you are really colour blind, you should be able to see something there.”
But let’s put the surface absurdity of the statement aside for a moment… Should? Based on what? There are two possibilities here.
A. I can see the answer
B. I can’t see the answer
If it is A, then I’m lying when I say B. Surely there is nothing to be gained from lying to her. There is no draft that might send me to an overseas military conflict. There are no financial aids given out to the colour blind. All factors are equal, and given that she doesn’t know what the likelihood of me telling a lie is (i.e she has no record of the truth/falsity values of every statement I’ve ever made which could suggest a tendency to lie), how can she assume that I “should be able to see something there”? There is some probability for B according to the small amount of reading I’ve done on the subject; there is a type of colour blindness with a much lower presence in the population than other varieties.
Now, here’s my question (and please do answer in the comments if you have an opinion, or especially if I have gotten something wrong factually):
Is it something to be concerned about that a philosophy student can (apparently) have a better grasp of critical reasoning than someone who told me a contemptuous tone that she was “more scientific [than people who are enrolled in non-science courses]”?
There's something else really interesting at work here though. We seem to be running into an epistemic barrier in a situation like this. My optometrist can't actually see the world the way I see it, no matter how hard she wants to. And I can't see the world the way she does. This is starting to scratch the surface of what the Australian philosopher David Chalmers talks of when he uses the phrase "hard problems". Although I think some of his arguments are quite weak, I think he's right to speak of the hard problems. I’m really curious as to what condition I actually have, so I have requested to go back for another appointment. We’ll see what happens.
