Talk about a sight for sore eyes.

U.S. Air Force veteran Mark Cornell has been legally blind for two decades, but thanks to some high-tech glasses, he is able to see again.

A touching video captures Cornell's tearful reaction when he first tries on a pair of eSight glasses - which use a camera and advanced computing to create real-time video that can be enhanced and magnified for people suffering from vision impairment.

Cornell and his wife appeared on "Fox and Friends" this morning to discuss his "eye-opening" experience and how this technology can help others.

"It's just an amazing piece of equipment that allows me to be able to do this and to be able to look at my wife and say, 'Wow, you look the same now as when I first met you,'" Cornell said.

"This could help tens of thousands of people, if not hundreds of thousands, both veterans and their civilian counterparts," the 18-year Air Force veteran said. "Maybe not perfect 20/20, but crying out loud, just to be able to go to a store and read a label."

"There's no words that I can say except for, 'Thank you.'"
