Many (most?) states' DMV require re-testing of the eye exam at every driver license renewal after a certain age. How soon is your husband's renewal due? That might be a way to get his license taken.
Accidents and injury is a very real concern. My dad was still driving at 91 (!!). He started having AFIB episodes where he "zoned out" for several minutes. This happened when he was driving home one day from the post office, and he ran into the back of a truck at a stoplight, then went off the road and rolled his car. It could have been a lot worse as it was, he broke his thumb. The car was totalled. When he came home from his follow-up (my cousin had taken him), he walked in and announced he had decided not to drive anymore. I suspect his doctor told him it was time to stop, that the situation could happen again, and that he would never forgive himself if he hurt someone else.
Perhaps your husband's PCP could talk with him about which daily activities are becoming difficult?
