If your child can't see well, you might expect him to tell you things are fuzzy, or complain of headaches. But a surprising number of kids' vision problems are never picked up, and the children end up exhibiting behavior or learning problems.

One out of four kids in school may have vision problems, which leads to some unexpected issues.

"Some kids are labeled as learning disabled, ADD or ADHD, or some are just labeled as lazy, they don't want to do the work. The child could act up in school because it's hard for them to concentrate up close, hard for them to focus, hard to keep their eyes on the page," said Dr. Ida Chung of the SUNY College of Optometry. That's one reason doctors recommend kids get their eyes checked at age 1, 3 and 5, especially since some eye problems need to be treated early or they turn into permanent disabilities.

Also realize that children may not tell you they are having trouble because they don't realize that the world isn't supposed to be all blurry.
