If your daughter's doctor gave her a prescription for strep throat, you'd be sure she used it correctly, right? The same goes for contact lenses. If your child's lenses are labeled for daily wear, then that's how they should be used. Removing contacts each night gives the eyes a break and allows oxygen to reach the cornea. If she occasionally forgets and conks out with them in, it's probably no big deal, but if this happens on a regular basis it could lead to infection or injury. Encourage your daughter to be more responsible for the care of her eyes -- we're sure she'd rather get with the program than have to go back to wearing glasses.
