Aug. 16 -- Ten years ago, Lisa Reid lost her sight. But last November, while reaching down to kiss her beloved guide dog Amy, Reid says an accident turned into a miracle and she could suddenly see again.
"I kind of lost my balance," she says. "[I] hit my head on the floor and coffee table at same time."
In one mystifying moment, everything changed, as she regained the vison she had lost at age 14.
"It wasn't scary," Reid, 25, tells ABCNEWS' Jay Schadler. "It definitely wasn't scary. It was the most beautiful thing ever."
But some doctors are skeptical, unable to find a medical explanation for Reid's recovered vision. Some have even suggested that her blindness may have been more psychological than physical all along.
But whatever the explanation, Reid says her life has been transformed. Though her eyesight remains imperfect, a world long hidden is visible again.
Life Saved, Vision Lost
Reid was raised by her hard-working mother in a tourist town along the northern coast of New Zealand after her father had abandoned them. When she was 11, she developed a cancerous brain tumor.
"It was slowly suffocating me," Reid says of the headaches, vomiting and loss of coordination that accompanied the cancer.
A delicate operation removed the tumor and saved her life. But her optic nerves — which carry visual information from the eyes to the brain — had been permanently damaged.
"She's got optic atrophy, or damage to the nerves that join the eye to the brain" says Dr. Ross McKay, an ophthalmologist in Auckland, "A result of the raised pressure inside her skull caused by her tumor."
As Reid's eyesight faded, so did her connections to the world she once knew.
"My ophthalmologist basically said to me that I was never going to see again," she says. ""Having something so precious taken away from you… you just think it's quite unfair."
Asked what she missed most when she lost her sight, Reid says, "Probably myself. And I don't mean that in a vain way, I mean that in the sense that I couldn't see myself physically, but… I couldn't see myself inside either.
