Make sure you share this with a professional. The eye nerve also relies on dopamine which PD affects in so many ways. So it may not be an age issue but a PD issue.
I think that comes with age.
I don’t even try to drive at night. I also have a cataract in right eye. 🤪
Personally I haven't driven at all in 2 years. My doctor says it's not a good thing and I have a chance of passing out at the wheel. My wife drives everywhere thank the Lord.
I 'm in the same boat. Can't drive at night, or in heavy rain - not good for an Oregonian, lol.
