Nance Eldridge Coffaro focuses the camera on the wig, watches the monitor, and begins to work out the style. Once that's done, "I can do a lot of it by feel," she opined, "I'm amazed by how much I do by feel.”

Coffaro had been styling hair since she was a teenager. But was forced to give up salon work due to her blindness. She was diagnosed with a genetic disorder that causes the optic nerve to atrophy.

She is able to make out light and shadows within a few feet.

For the last six years, Coffaro has been styling wigs for the theater group. Once she lost her sight she thought her wig designing days were over. "That first year was very depressing, having to give up work in the shop, theater, driving. I was the main driver. I had a good sense of direction. Suddenly, I'm out of work," said Coffaro.

However, with the help of a monitor hooked up to a powerful camera that has the capacity to magnify images up to 100 times, she is able to continue as a wig designer.

A caseworker from the New Jersey Commission for the Blind & Visually Impaired (U.S) told Coffaro about the device. "When I had a newspaper under the device and could read a couple words, I started crying," Coffaro reminiscences. Slowly, she became comfortable doing her work with help of monitors and cameras. And she was back in the theatre circle.

It's not perfect. She misses being a colourist, as well as being able to stand back and survey the finished product on opening night of the plays. "I would never expect customers to sit with a monitor on them,” she says cheerfully.
