Since both sides have their recommendations, I will not make one. Instead, I will tell you at 45 years of age, I got the progressive no-line and had no problem adjusting to them at all. All one has to do is to remember that when you want to look at something far off, you raise your eyes and not your head. If you want to read something you lower your eyes and not your head. You look through the top of the glasses for far away and look through the bottom of the glasses to read or do close-up work. I am now 65 years old and wear my glasses all the time and find that the bi-focal really helps when tying flies. I use clip-on polarized sun glasses when fly fishing. They even have clip-on ones that you can flip them up when you do not need them in low light situations and flip them down in bright light.
