I have been to 3 different optometrists in the past year who have all told me that my eyes look physically fine. One of them completely dilated my eyes did multiple tests for my peripheral vision as well. I have what I would describe as visual snow, flickering light occasionally, and sometimes see light spots. The spots when I turn my head seem to be symmetrical in both eyes. When I turn my head left my eyes will be looking to the right and I will see the spot in my left eye towards my nose. I don't understand why they are there and I wish I could get a real answer. It bothers me most when I am in the shower as I seem to be able to see them more. Could it be a neurological problem? Is it something I should worry about? I just don't want to lose any of my vision.
