Hey. I'm sorry about your condition. I feel I'm approaching blindness eventually, this is very random, but perhaps you could share any resources I could learn to prepare for this so I could continue using the web when/if it happens.
If you have Android:
https://blindandroidusers.com/
I believe Hadley is still a good resource: https://hadleyhelps.org/welcome-hadley
I hope this helps get you started.
