CLEVELAND -- Having 20/20 vision may not be enough for your child to see what they need to learn.

Certain vision problems cause 25 percent of children to have poor grades and slower development. But as NewsChannel5 reported, there is a solution called vision therapy. And some parents are singing its praises.

Elise Previtera, a sixth-grader, traditionally achieved straight As but was getting solid Cs.

"I was always crying and saying to my mom 'I'm stupid,' and stuff like that. And I would always get really angry when she would tell me I had to read," Previtera said.

Things changed as soon as Elise got vision therapy.

"It was a dramatic difference from not being able to read to reading," Elise's mom, Susan Previtera, said.

Vision therapy helps people get better control of their eyes so they can process information easier and faster. Using personal evaluations, optometrists determine what activities can strengthen vision functions.

According to Dr. Drusilla Grant, an optometrist that practices vision therapy, "You need to be able to look, listen, think and do. And if all your energy goes into looking then there's not much left to think and do."

Alix Harwood, 7, suffered from that problem, and some others.

"The temper tantrums were so hard to stomach that I knew that there had to be something going on here. So I thought we'd try it for a couple visits, a couple of months, see how it went and see how he responded to it. It was miraculous needless to say," Lundy Harwood, Alix's mother, said.

The American Academy of Ophthalmology said there is no evidence that vision therapy corrects learning problems, but Grant begs to differ.

"Many, many have benefited, and there's nothing we can do to deny that. I mean, parents tell their own story," Grant said.

Interested parents should note that vision therapy is not a treatment option for learning disabilities and may not be covered by your insurance company.
