Funny you should say I have good eyes. I've actually been slowly going blind for several years now. A combination of macular degeneration, vitreous separations and torn retinas have given me the vision of an eighty year old, thirty years early. My older brother went legally blind two years ago from similar bad genetics so I'm making the most of what I have for now.
The "eye" for a good scene was something my mother taught me as a child, and was further developed when I took up watercolor painting back in the early nineties.
You have my sympathy over your eyesight problems, I have just been diagnosed with vitreous separation in my left eye and am waiting on an appointment to see if there is any damage to the retina.
At the moment I'm just suffering from the activity of floaters that I liken to a manic trapeze artist swinging around randomly across the vision of that eye.
