Lisa Reid from Auckland, New Zealand, alongside her guide dog... In November 2000, a 24-year-old woman bent down to kiss her guide dog goodnight, accidentally struck her head on a coffee table, and went to bed. When she woke up the next morning, something extraordinary had happened. She could see again. Lisa Reid had lost her sight at the age of 11 after a brain tumor damaged her optic nerves. For years, the New Zealand woman had lived in a world she could no longer see, learning to navigate daily life with the help of her guide dog, Ami. Then came the accident that would change everything. On November 16, 2000, Lisa leaned down to kiss Ami goodnight, lost her balance, and bumped her head against a coffee table. It seemed like an ordinary household mishap. She went to sleep without expecting anything unusual. But the following morning, colors and shapes began appearing where there had been darkness. Lisa could see again, although her vision had not fully returned. The emotional surprises were almost as remarkable as the recovery itself. Her younger brother, whom she remembered as a little boy, had grown into a man with a goatee. Her mother had aged. Faces she knew through voices and touch suddenly had features she could study. She was seeing years of change all at once. Doctors could not establish exactly why her vision had returned or whether the blow to her head had caused it. The recovery remained medically unexplained. Years later, Lisa was still living with the extraordinary consequences of that November morning. A woman who had spent much of her youth without sight had awakened to discover that the world, and everyone she loved, had continued changing while she could not see them.
