A couple days ago I started noticing a flash, almost like an afterimage from a camera flash, just a small circular area
in my lower left peripheral vision when blinking and
in my right eye only. Couldn't see it any other time, sounds a lot like the "mystery" spot others on this forum seem to have.
Anyway, I went to get it checked today, my regular Dr. was booked so I saw the optometrist on staff.
