A girl who is legally blind was able to see “The Nutcracker” on stage for the first time thanks to a pair of specially designed glasses.

Lily Lueders, a 9-year-old in Austin, TX was born with optic nerve hypoplasia when she was a baby, which is a disorder that affects the development of the optic nerves. Because of the disorder, Lily is completely blind in her right eye and partially blind in her left eye. Her mom, Kimmy Lueders, says she can see about 3 feet in front of her.

Dell Technologies put together a special presentation of “The Nutcracker” by Ballet Austin, where she was given specialized eyewear called eSight, which are “visual assistive technology” glasses that allowed Lily to see. Dell called the event the Unseen Ballet, which welcomed other people with visual impairments to also see the performance.

The glasses use cameras and high-resolution screens to show users what’s happening right in front of them. Lily was able to see the ballerinas doing their intricate moves more clearly than she would have without the glasses. Dell also arranged for Lily to go backstage and meet the ballerinas.

Lily’s parents learned she had the disorder when she was 3 months old. She currently attends occupational and speech therapy multiple times a week to promote self-awareness.
