Has he been taken to a vision rehab center? That should be first on the list because the vision rehabilitation will reteach him a lot of skills that are very visual and teach him about a lot of assistive technology that can be useful to him. He should also see an orientation and mobility specialist if he hasn't yet.

Macs and iPhones/iPads are great for people with vision impairments. They have accessability options built in, like zoom, voice over, contrast, large text, etc. I don't know how blind your brother in law is, but he could benefit from these as well. PCs have things like JAWS, ZoomText, and other programs that you need to buy but Macs have it all built in. Ipads have a lot of apps that are useful as well, like a money scanner.

There are still a lot of hands on work that he can still do. A lot of people with vision impairments can do carpentry, pottery, woodworking, and weaving. People with vision impairments can do a lot of things. I have a friend who is majoring in computer science and is doing grad work. Another friend of mine is going be a teacher for the visually impaired, like me. Other high school students I observed want to do sports management and even play sports.

There's this one really cool sport called goalball that is made specifically for people with vision impairments that even sighted people can play. Everyone is blindfolded to make it an even playing field. Basically, you roll a ball with a bell inside and when it gets close to you, you use your body to block it. If the ball gets in the goal, then the team scores a point. It can get really intense at a high level. You can look up the paralympic goalball highlights to see if your brother in law would be interested. If you can find a league near you, I suggest joining so he can meet others who are blind and do something fun and active.

I get this feeling from being on r/blind that Canada is way better at rehabbing blind people and providing services. I could be wrong, but it seems like the majority of the most vocal and independent blind people on this site are Canadians. Not going to lie. As an American, I am feeling a little jealous. Canadians also have the best guide dogs.. unfortunately they are only for kids.. but still! Okay, fine I admit it, I am feeling a lot jealous.

He has to accept that life has changed. Most assuredly he is and will experience grieving the loss of his eyesight and his significant other. Living blind doesn't have to be the bleak outcome that most people think it is. As mentooned, there's a rich blindness community all over the world. Perhaps tell us what city he lives in and someone can direct you better. Because the truth is, most blindness related services, groups, and resources are not well advertised. Why would they be? We'd never see the ads! Lol

Personally, I have been to e-sight headquarters and tried them. Even with the help of a head engineer, I found the experience less than stellar. Also, no way do I consider the device worth the asking price. It is not innovative tech. Others will disagree, but old fashioned blindness skills that help a person live independently can never be replaced by gadgets that hope to imitate sight.
