Some great replies so far - I just wanted to say sorry to hear about this and agree to research and prepare as much as possible now.
I remember a Val Kilmer movie a while back called
At First Sight that was pretty good about blindness. Co-star was beautiful Mira Sorvino and it was based on a true story.
There's so much technology now to assist those with disabilities - especially in communications.
I wish you the best going forward and hope you will keep us updated down the road.
