A couple of weeks ago in a lesson at school, I couldn’t concentrate as out of the corner of one of my eyes, my vision was blurred. it looked like when your eyes are watering, but they weren’t. My eyes were really sensitive to the lights so it was hard not to squint. and I did have a really bad headache for a while that day. But by the end of the day , it was gone. Was it a migraine? and was it an aura or blind spot?
