I've found that I need to change the type of glasses I wear when walking. I needed a separate pair, dedicated to walking, yard work, and they are fine for driving as well. I used to wear progressives so the lens progressed from distance to reading, but with the onset of PN, that transition from distance to close up made walking a nightmare. The ground was not where it looked like it was. What my eyes were seeing was not what my legs were reacting to when I stepped down on rough ground. I've learned that if I am wearing glasses with a progressive lens, I'm better off not looking at the ground before stepping off, especially on known terrain as in my yard. I know how far it is from my front porch to the ground right below it, but what my brain registers because that is what my eyes see through the deceptive glasses, isn't what is really there. This has been a whole new learning curve. My next purchase will be a new pair with an up to date Rx for distance (with prism) but NO progressive. They'll be used for yard work, walking, and driving. Just don't ask me to read any fine print with them!
