Well, the inevitable happened. At 55 I had to start using reading glasses on airplanes. My youthful vision prior: 20/14. Now at 66 I found myself using the reading glasses when driving to help read road signs. Went to the eye doctor and as expected eye glasses are in my future (diopter correction and some astigmatism) . Ordered a pair of sunglasses that should work for riding. Isn't aging grand? Good news is that the glasses should correct me back to 20/15. (Haven't looked into laser surgery yet)
