I used to look directly at the sun when I was a little boy. A bright blue disk would burn itself into the center of my sight and remain there for a few minutes. I would sometimes burn several of those and walk into things, half blinded, at my grandparents’ house. At home in Jastrzebie Zdrój, I had a magnifying glass that helped me burn holes into paper. Never burned holes directly into my retina.
I also liked and still like the hundreds of blue spots that fly away, so it seems, over snow. I sometimes just stare at snow for a while and there they are, in various formations. Rubbing the closed eyelids for an extended time can be fun too, as carpets of color dance and glare up between the eyelid and the irritated eyeball. All of these are self inflicted eye injuries. Then there are these other artifacts somehow sticking to my eye-lenses. Tiny particles of dust, maybe scratches, keep flying around the room now, as my eyes are growing older. I do not see them all the time, of course, just sometimes, when I really want to focus on them. Maybe it is time for me to wear those Florida glasses.
Oh, my eyesight is pretty good. I am sly far sighted, but have not required any kind of ocular aide so far. (He knocks on wood.)
