eyes and imagination

eye doc says i'm definitely losing some nerve mass in my right eye, so i've gotta go back to get rechecked in three months, and get my eyes dilated again in six months ('cos that's what insurance will cover). he's just getting a baseline, really. says if it's glaucoma, the peripheral vision will be affected first, and it's treatable with eyedrops. so i don't need to learn braille. yet.
