Are symptoms related to tears in my retinas?
I have been told that I have small tears in my retinas and this is what is causing the flashes of light that I see. I also have noticed that when I cover one eye and look intently at the wall or ceiling, my vision seems to go dark grey. The second that I move my looking eye, it's back to normal again it doesn't seem to happen when I am in a well lit area, like outside. I am trying to figure out if these symptoms are connected with the other ones or if this is a new concern. I also have underactive thyroid.

You should see your ophthalmologist immediately if there is any possibility that you have a tear or tears in your retina, of any size. Occasional flashes can be caused by traction on the retina, which is not harmful if it does not produce a tear, but if there is a tear it needs to be treated.
