I'll give this a shot. Some do’s and don'ts:
Do-have at least 20/40 vision in one eye. This is a law in most states.
Do-consider using Google Maps or some other audio aid to announce turns and directions.
Do-consider alternate means of transportation like friends, family, Uber or Lyft, public transportation like a bus or can.
Don't-drive at night if this has become difficult for you.
Don't-miss eye exams and make sure your optometrist sees you regularly. And your optho and RS as well.
Don't- despair! You are not alone. Many members of this site and our community have walked this path and are willing to help and advise you. Best, Richard-Advocate
