An Ophthalmic Migraine. An Ophthalmic Migraine occurs when zig-zag lines or "heat waves" show up near the center of one's field of vision and a blind spot expands on to one side--of the field of vision--for several minutes, though, usually less than an hour. These are sometimes followed by a headache, sometimes it's not. Some people experience them once and some people experience more episodes throughout their life. No medical treatment is entirely necessary, though, if these occur on a regular basis, you should contact an Ophthalmologist, preferably your family Ophthalmologist.
I was at school doing my Geometry work and out of the blue, I had an eyegrain. It bothered me and I couldn't finish the rest of my work until it was over, though, the bell rang right after it finished.
When something causes so much pain to you, that it produces this symptom.
Can be used as an insult from a person dressing bad, to being used as a descriptive term for severe headaches.

Alternatively: my head is poudning and this eyegraine will not go away.
