Usually, any type of conversion disorder causing blindness has a traumatic or highly stressful event/antecedent that precedes it, but I'm sure he's been tested for that possibility by his specialists.
If he likes to read, he should qualify for your state's and the BARD NLS free talking books, magazines and newspaper program. They usually send out a free digital player - or your can buy your own - and send pre-recorded thumb drives with whatever pre-selected material or books he'd like to read and return by mail, or you can download the books, mags, etc., from the BARD NLS website to your personal thumb drives to plug into the player and listen to. An 8 GIG thumb drive can hold as many as 60 - 80 audio books. Call your state's talking book program for the blind and disabled as even those temporarily unable to hold or read printed material for whatever reason can usually quality for it as long as they can't access reading material any other way. The agency can tell you what he needs to qualify for it and how to get him started on it.
