It happens to a lot of us. I would say before you give up on driving completely to get a fresh eye exam. Explain the situation to your eye doctor and ask for professional opinions.
I am 77 I have had dry eyes for over 40 years and at times it makes my vision an issue. I also was told 17 years ago that I had macular degeneration. I now understand that it is dry macular degeneration. I haven't noticed any issues with my vision other that needing frequent updates to my prescription glasses. I take UpNoursh ARED2 plus and Sight Care supplements. I also use Refresh Tears eye drops. Refresh gel for dry eyes and at night eye ointment at bed time. All of that together has kept my vision in as good a shape as possible. I don't have any floaters, blurriness, fogginess. I get my eyes examined every 6 months. And normally need new glasses at least yearly. As long as I wear sunglasses outdoors and tined glasses in rooms with extremely bright lights am am okay. I am an outdoor person that hikes, walks, and camps.
