From playing Grieg to Chopin and many of her own creations, 26-year-old pianist and composer Jennifer Castellano can solo with the best of them. But she also often can't see the music she's learning to master.

"I was born with corneal opacities in both of my eyes, which clouded over," explained Castellano. "The corneas prevented me to see out of it, so I underwent corneal transplants, which improved my vision somewhat, but I'm still legally blind."

While Castellano is able to memorize a lot of her music by ear and from following Braille, she can also call on some of the latest technology at Lighthouse International's Music School. Using the "Finale" computer program, the school developed special computer templates to enlarge music to help students not only learn, but also compose.

"Our message is that you can continue to be a musician regardless of whether you have vision or not," said music school Executive Director Leslie Jones.

That's also very much the case for 18-year-old violinist and Manhattan School of Music student Allan Bailey. At age five, he was diagnosed with optic atrophy. But instead of music being blown up to see, a special device called Joint Optical Reflective Display, also called JORDY glasses, is able to do the work for him.

"The main impediment was reading music at a distance where you could play the violin as well," said Bailey. "I mean, you need roughly two-feet away from the stand to be able to see that and it was gradually getting worse."

The electronically-charged glasses help Bailey, magnifying music up to 50 times. JORDY glasses even have a zoom component.

While the glasses are able to help Bailey, his teacher says there are still some drawbacks to the technology.

"Mechanically he can't produce the proper sound because the equipment is too close to the bridge and the strings," said Patinka Kopec, an instructor at the Manhattan School of Music. "So he needs to memorize everything quickly so his eyes are not focusing on the page."

And while ophthalmologists agree there's is room for improvement, so far the technology has come a long way. Technologists are currently working on glasses and even implantable electrodes to be placed under the skin that may have video playback directly to the brain, opening not just a new world of music, but other endless possibilities.
