When this happens, a blind spot
forms in the central part of my right eye, I see jagged, geometric shapes that shimmer with bright colors, and there's often flashing lights in my peripheral vision. This only occurs in the right eye (left is fine), and the visual symptoms go away after around 40 minutes.
Following this ocular migraine, my right eye is in a fair amount of pain for around 36 hours. It feels tight and stiff, and very sore.
