Molly Watt lives with Usher Syndrome. From the Wikipedia page:

Usher syndrome is a relatively rare genetic disorder caused by a mutation in any one of 10 genes resulting in a combination of hearing loss and visual impairment, and is a leading cause of deafblindness. Usher syndrome is incurable at present.

Molly and her mom each got an Apple Watch about five days ago. From Molly’s blog:

I was born deaf and registered blind when I was 14. The condition I have is Usher Syndrome Type 2a. I am severely deaf and have only a very small tunnel of vision in my right eye now so I was concerned not just about the face size but how busy it would appear to me and also if there would be an uncomfortable glare.
