Son wore sports goggles all the time when young. At 11 he went to contacts. He had some stigmatism, and each eye was different in prescription. It was super stressful for him to put them in the beginning. As I've never worn contacts, I couldn't really help him. He had to learn to handle them himself. Plus a dad hanging over a kid telling him to hurry up, get them in, let's go.
HIs contacts, "daily disposables" arrived a day before his first tournament without glasses. He was scheduled to pitch to pitch an 8:00 am game. I wanted to give him plenty of time to get them in, but I'm also the "if you're on time you're late guy". I leave him alone in the hotel bathroom to put them in. No pressure, plenty of time. He's in there forever. I start to stress on the time, then it boils over. "C'mon son, hurry up!" Nothing from the other side of the door. "Hey, LET'S GO!". Finally, he opens the door. About 10 empty contact dailies opened and on the counter or floor. We leave immediately for the fields. We're late.
Son keeps saying "I can't see right." I tell him it's an adjustment, you'll be fine just like the doctor said. He goes straight to bullpen to warm up. Game starts in 20 minutes. I go to the stands and hang with the other dads. About 10 minutes later, I see him on the bench and another kid warming up. Coach calls me over. "He can't throw a strike. He also got hit three times by the catcher throwing the ball back to him and is mad as hell."
Turns out he had the left contact in the right eye, and right in left. Oooops.
