For the past month my eyes are getting worse. To me it seems like I'm moving through fog/smoke. It increases to maximum extent in sunlight; when I see Sun directly even for a few second, the fog in front of my eyes increases and my head starts spinning to some extent.

Normally, my blood pressure is low but 90% of the time when fog appears in front of my eyes my blood pressure is slightly above than normal.

I'm sure that it is NOT related to any eye problem. Blood pressure is also NOT the root cause, although it might be effect of something else going on in my body.

Does anybody know what serious issue/disease could cause the fog/smoke in front of eyes (sometimes low sometimes high)? PLEASE HELP!
