Hey ladies, can anyone tell me why my 10-year-old daughter's eyes might be hurting? I've got a doctor's appointment for the 14th, but I was thinking of waiting. Still, I think I'll take her to a private clinic tomorrow. She's uncomfortable with bright light, her eyes aren't itchy, and there's no discharge. Has anyone experienced anything similar? She seems to sleep fine, about 9 hours, so it's definitely not lack of sleep.
