It
turns out your prescription can improve. I always assumed it was just
an inevitable downhill progression but, no, my eyesight has actually
improved marginally over the last five years. Turns out this isn't
uncommon, though it usually happens with people in their forties or
fifties, that the ageing process of your eyes can even out
deformities.
They
took pictures of the inside of my eyes and showed them to me. They
wouldn't let me have copies, though, but it looks kind of like a red
lava lamp made out of skin.
I
had a nice chat with the opticians who did my tests, we discussed the
purpose of various machines they used on me. There was an almost
arcade machine thing where I pressed a button every time I saw a
light flash that was testing my field of vision. The only one they
didn't want to discuss was the one that blows a really cold, really
intense puff of air into your open eye so I'm beginning to think that
one actually serves no purpose and just gives them a sense of power
as they force you to go through it again and again and again.
Just
a thought, that last one.
Of
course, any time I get new glasses I feel the need to dig out this
Peanuts strip (sadly this is the best version I can find through
Google):
I
tell you what though: going from round frames to square does odd
things to your peripheral vision. Its like someone's been messing
with the field of view slider.

The puff of air thing is for glaucoma, I think.
When I do the field of vision test I normally have to wear my glasses because otherwise I have difficulty seeing the lights.. I have very poor vision and they are bright green on a bright white background!
Eye tests are interesting.
That explains things, they probably didn't want to go into it in case I worried (there's a history of glaucoma in my family). Cheers.
