jOe,
I have a few risk factors that came together, to increase the chance it would happen. White male, over age 50, with a long history of myopia. People who are nearsighted have eyes that are not spherical, more football shaped, and a weaker retina attachment than is normal. While a retina CAN be detached by trauma, in a guy like me, it can happen in your sleep, for no other reason than protein accumulated in a spot, and started a tear in the gelatin that holds the retina in place.
It sucks , trust me.
Best,
Ted
