Know the feeling regarding driving.
We do not have to take a test but declare any sight or other problems that may affect your driving.
If you do not declare them, big trouble.
I have to have an eye test every year and if not meeting the requirement the optician would report it to the DVL.
The doctor would also report anything he/she thought appropriate.
After 80 you have to renew your licence every three years, would be a real handicap if I could not drive.
Hope you sort things out.
Regards.
