Map of eye phenominon - Discussion
This is a cool flowchart of eye related phenomena. (I love flowcharts and maps)
Check out wikipedia for even more cool visual varieties.

Hi DW,
Thanx for the post, I downloaded the eye chart to have a closer look, really interesting. I think most of what is described there could be explained by physiological phenomena, like cells sloughing off the inside of the eye and such. I have really bad myopia, strabismus, and astigmatism so my eyes tend to collect this kind of gunk. Since I had one lens replace due to a fluid cataract (kind of catract that develops really quickly and is very difficult to detect) I'm told that I need to watch out for flashing and parts of my visual field going dark as these are signs that a retinal detachment may be in progress. It's fairly easy to fix with laser surgery, but you need to get to a doctor within 48 hours. People who have had any operations on their eyes have a higher lifetime risk of retinal detachment.
But I think the other bit does have some connection with meditation. In particular, when I've done heavy concentration retreats, I tend to see little sparkles everywhere, like stuff is giving them off or they're getting generated by space. Since its unlikely to come from the eye, I think most likely this has something to do with the effect of heavy concentration meditation on the optic areas of the brain. Not sure what to make of it, but it does seem to fit in one of his categories, Blue Sky Sprites or Spots. Also, the hallucinations, they're old and mostly unwelcome friends.
