My son was sitting at the table today in a moderately lit public place with overhead lighting and high ceilings with lots of natural light. It was a cloudy, very overcast day. He suddenly put his hands up to both eyes and complained that the light was in his eyes, then bent his head down. I asked what he meant and he said it was like when you look at a bright light. He kept his eyes covered for a bit, and then it went away. It happened again within several minutes, with the same response. He's never had this before, and I don't expect him to have it again, but wonder what it might possibly be. Incidentally, he just had an eye exam last month and it was perfect.
Any input is greatly appreciated - thanks!
