Many children perceived to have a learning disability may just need glasses, experts say.
Bad eyesight can mean a child can't see the chalkboard, which can lead to poor grades.
"When children are diagnosed with a learning disability, about 60 percent of the time it's just a vision problem, and then once they get their glasses, they come up to speed," said Dr. David M. Redman, of the California Optometric Association.
A pediatrician's eye exam might not be enough. One doctor recommends a thorough eye exam at ages 1, 3 and 5 and every year after that. Children as young as 9 months may need glasses.
