A woman who became blind at age 11 while battling a brain tumor miraculously regained sight after hitting her head on a coffee table when she bent down to pet her dog.

Doctors are having trouble determining a medical reason for Lisa Reid's sight coming back after 13 years. Her sight returned over a decade ago, but she is just beginning to tell her story now to raise awareness for Blind Week in New Zealand. 

"I really can't find words to describe how it felt - amazing, fantastic. You can imagine not being able to see and then you can, you really can't describe that. To see the world again visually is a gift," Reid tells Independent.  

After hitting her head on the coffee table, Reid went to bed as normal. When she awoke the next morning, to her surprise, she could see again - for the first time since she was a child.

When Reid got her very limited sight back she got the chance to visually see her family for the first time in over a decade.

"He was a man ... with a goatee and everything. My brother's a man," Reid tells Independent. "When I saw my mum, I was like: 'You look the same but older.' I turned into a woman and my brother turned into a man."

She also had the chance to lay eyes on her fiancé for the first time, who she met through a dating service after she became blinded.

"I kind of knew it was him," Reid tells ABC News of her fiancé when she saw him for the first time. "I just knew it."

Some doctors who are skeptical of Reid regaining her vision are suggesting her blindness may have been more psychological than physical the entire time, a case that has happened to other patients in the past, ABC News reports.

Dr. Ross McKay, and ophthalmologist in Auckland, New Zealand, is torn because he remains convinced that Reid's blindness was caused by her tumor and he also does not believe in miracles, he tells ABC News.
