My 13 year-old son told me that at school today he was at his locker, blinked and then couldn't open his eyes all the way. They didn't hurt, he was inside so there was no sunlight, he just couldn't get them to open all the way. He said it scared him, which is unusual, so I know it had to be pretty severe.
He wears prescription glasses and has never had any problems with his eyes. Although he has complained that they hurt sometimes.
Any thoughts?
