tonight, all of a sudden, my right eye has some big floaters, and my vision got cloudy, with tiny specks, like sand, some specks are black, others seem faded and a shadow of the black specks; when sitting in front of computer screen, covering one eye, this is more apparent--vision in right eye seems faded, with the tiny specks and large floaters, covered in cloudy haze. I thought I had a stroke, but doesn t seem to be. I wear contact lenses, over the past week had extreme physical exhaustion from yard work cutting trees and fall clean up. I am male, 62 years old. It this a retina tear or detachment? Is this an emergency?
