What interests you most?
Try to find a mix. Consider what you do best. Consider what you most enjoy doing (which may not be what you do best). Throw in some other interest or consideration. And then surprise! you may be one of very few people in that field. Your low vision may be irrelevant, aside from difficulties you encounter finding accessible materials.
More briefly, combine what you...
1. Do best
2. Enjoy doing
3. Want to keep learning about
Then set yourself a very difficult problem to solve. Chip away at that problem bit by bit. That'll keep you busy for a few decades.
A significant advantage you have over younger students is that you've had more time to figure out what you work and hobbies you enjoy, and with what kinds of people.
Once you've found your mix and identified a field of study, connect with a few people who are tops in that field, or at least well regarded as teachers in that field. You'll likely make some good friends and get some further guidance.
I'll give an example, and I'll admit in advance that I skimmed recent posts associated with your user account. Let's say your mix would be the following:
1. You have significant work experience involving production machinery related to the print industry
2. You like to play and/or listen to music
3. You'd like to learn more about the medical field, including why certain medications cost so much, why accessibility for medication delivery hasn't improved, etc.
Based on the few posts of yours I've skimmed it's **abundantly** clear you're smart. With the \[non-audio\] mix mentioned above--print media, music, and medicine--here are some ideas:
* Medical technician specializing in music therapy (
$1 )
* Accessibility tester at a pharmaceutical company (
$1 )
* Multimodal medical therapies that combine music and medication for people with hard-to-treat illnesses.

$1 Once you figure what would be optimal for you, given your skills, interests, and desire to keep learning, then in about five years you might be one of twelve people with that mix. Total. Globally. That mix could make it somewhat harder to find a general job, but some organizations could be ecstatic just to learn you exist. And anyone who dives deep on a very specific subject is generally regarded as capable of diving deep into other subjects.
Given your own history of vision, you might choose to work with people with similar histories and/or similar conditions. But you wouldn't have to. There's definitely a shortage of people who have medical degrees and/or work in medical fields who have personal experience with significant vision loss.
You could even start by writing a blog about your experience. You write well. That blog would be nice to reference on a university application. How many middle-aged bloggers with low vision apply to university with a background like yours? I'm guessing few of them, making you a rare catch for the right university.
When you're applying to schools, if you want help or suggestions about your application, please let me and/or us know. Send applications to a range of schools. You may be surprised which schools would go out of their way to accept you.
