Sitting in my living room watching TV, after about 15 minutes something went
wrong with my vision, made me think I was either having a stroke or going
blind.
As I casually sat in my chair in semi-darkened room watching TV about 15 feet
away, all of a sudden my vision (except the tunnel focus to TV) starting going
DARK. I thought I was having a stroke, blood was pouring into my eyes, the
visitation of an angel coming. I blinked a bit and the room lightened back up
--my vision normal. Here is what I think happened: I believe that my irises
merely contracted (to near closure). As the irises pinched down, it had the
effect of narrowing my field of vision down to the central tunnel.
I am 50, normal health, somewhat low blood pressure. Am I going blind? If this
is a problem where my iris wants to stay fairly shut (that is: small in size),
what disease might cause this? What supplement might bring this effect upon me?
What can I take to normalize my irises --that is, sufficiently opened to take
in enough light?
