First, u/RealRebeccaRose might have some answers for you. She's also visually impaired due to albinism so she'll have a better understanding of what helps and what doesn't than I would. Rebecca is the administrator for r/LowVision.

Second, regardless of the mechanism behind your husband's blindness, Zoom meetings with city officials are part of his job. He needs to stop freaking out if he wants to keep this job. My biggest piece of advice to him is to relax. Everybody is uncomfortable in Zoom meetings. We;re all embarrassed and self conscious in front of a camera and we all get nervous speaking in public and Zoom combines them both. Tell him to remember he's not the only one who's worried.

Third, although I haven't attended very many Zoom meetings, half of them were audio only. We just switched our cameras off and talked. A person in a Zoom meeting who has their camera off has a little avatar of their initials displayed instead of a live feed when they speak. Again, I'm no Zoom expert but I doubt anybody will care if his camera is on or off after the first minute.

Yeah, the first minute. Unfortunately people expect you to show up on camera at first, just to get an idea of who they're talking with and what the setting is, especially if you're a new hire. Your husband needs to do that to make a good first impression. If he's reluctant to show himself they're going to assume the worst.

Forth, if he wants to go the fake it till you make it route, all he really needs to know is where the camera is. Most people in Zoom meetings, especially those new to Zoom, look below the camera at the screen. If he just looks above the screen at where the camera is he'll seem like a pro.

I don't want to make it sound easy because it's never easy stepping outside of your comfort zone. It takes courage. But it's not harder because he's blind - Zoom is hard for everybody at first. I tried on like six different shirt and tie combos my first time. But it's really just a fancy way to make a phone call.

If he landed a wife as articulate as you I'm sure he's got what it takes.

Windows has an inbuilt magnifier that's pretty good (so does MacOS). You'll see part of the screen at once, instead of the whole thing, blown up to 2, 3, 4, whatever you set times normal size. I think it's in Accessibility Settings, but I enabled it once when I set up my computer, and haven't touched it since, so I don't remember exactly. If he hasn't already, he may want to also turn the brightness on the monitor way down. those two things together should greatly reduce the need to squint.

If you're a meeting participant, Zoom is pretty straight forward, and alot can be done with the keyboard alone. Alt+A mutes and unmutes your mic, Alt+V turns the camera on or off, and there's a keyboard shortcut to raise your hand...Alt+Y, I think? Don't quote me on that one, as I might be misremembering; I don't use it as often.

All if these comments are great. My daughter has albinism and alot of my job involves zoom calls with VI adults.

So for my daughter we use a home cable from the laptop to the tv(larger screen) sometimes we've stacked books Velindre the TV and placed the laptop peeking over the TV and other times we've but the laptop slightly to the side and angled so she's looking at the telly and the caller is looking at her side profile.

That way she can go as close to the screen without blocking the camera

I've learned so much about zoom since covid.

There is also a setting at the top right corner which is gallery view, it has all participants on an equal size square,toggle it and the person with the most noise shows up larger. In theory that sounds good as it's meant to be for who is speaking but whoever has a vacuum or dog barking in the background actually shows up!

Yes ask for any documents/presentations to be sent in advance.

Any adults with albinism I know use it with no issues one fully blind man I know has his camera off and uses a photo of himself instead

My employer and team have never had an issue with me having the camera off.
If the real reason isn’t enough I’ve heard many people turn theirs off due to internet bandwidth issues

The only thing I could see being a major issue is if they're asking him to give feedback on something shown in a presentation. He may want to learn how to use the in-built magnifier on the operating system. It sounds like his eyesight isn't really that bad in the grand scheme (I know, everything is relative), but completely blind people use Zoom all the time.

I'm not that far off that myself, and I use Zoom every day. On Windows, Zoom works well with a screen reader, but there's a bit of a learning curve involved.

Have a practice Zoom session where you call in to his computer and have him learn how to mute and unmute himself (the most important thing), turn on and off the video, and maybe use the magnifier. Honestly, this is more a of a social and psychological problem than a technological one.

The other comment on here suggests that you can turn off your video after the first minute. This true in some social circumstances and not true in others. I'd follow the cues set by colleagues in the meeting. In many contexts, turning off the video for more than brief periods is frowned upon. If someone is sharing their screen or giving a presentation, it may be a little easier to get away with having your video off. Half of doing well in a big Zoom meeting is sitting and looking performatively attentive. This is annoying, but it is what it is. I do play the blind card to get out of some of this, but that's because I've disclosed by disability and people know about it.

One rec for getting close to the computer screen - buy a separate webcam. I have this issue on my computer where if I want to see the screen and I'm using the built-in cam, it would look really awkward. But an outboard cam set up at the right angle makes this far less of a problem. I also use the on-screen magnifier, but when I'm on Zoom if I need to read something during a meeting, I'll use a keyboard shortcut and scroll to zoom in a lot more than I usually would, so I don't have to get so close to the screen.

I think his stubbornness is the main issue here and his trying to deny his disability and blindness and trying to hide it.

I am totally blind a lot less vision then him and I use zoom on a regular basis. Many of us do. And I don’t make any excuses about it. It’s just an excuse.
