keryxI went to the contact lens tailor. We're just fitting my left eye for now, first by trying on contacts to get the right curve, then by doing the refraction thing where they figure out what your prescription is.
There were numbing drops and yellow dye involved. She now has the info to order contacts with that prescription and curve, but bigger & with different edges - essentially, made to fit me.
If your cornea is misshapen, light coming into your eye isn't perceived by your brain as "straight" [This is a vast oversimplification of physics and biology; play along with me.]. Over time, your brain just starts filtering out what it doesn't understand. Then it stops telling your eye to focus, since really there's just no point.
So. When you put in magic (very uncomfortable so far, but I'd find size 6 pants uncomfortable, too) fake-cornea lenses, it's really hard to see. It takes work. And after 20 minutes or so, your brain might just white-out the signals it's getting from the weird eye. Hrm. That's interesting.
The contact tailor asked what insurance I had, then said "Oh, do you work at Wilderness Office Park?" - apparently a) our insurance covers the whole process, yay and b) she knows this because several other Wilderness Office Park peeps have my same fairly rare condition. She said at least 20 this year, which is about 4 times the rate of occurence in the population at large.
