The iriss size would not have such an effect, even a pinhole can serve for
the eye. If I may ask, why not consult a doctor? On a weekend the
emergency room is available. Blood pressure could be involved, especially
since it changed in such a short time. Please do see a doctor.
Quoted message said: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?
