Not that it matters, but the seamless glasses are usually called "progressive lenses"
The lenses that darken/lighten are usually called "transitions" (photochromic)
the ___focal lenses have lines of demarcation between the different areas.

Yes, you lasted longer than I did.

I've always had perfect vision. I noticed when I was ~41 that my left eye was changing. The right eye was fine for a long time. I think I started using readers when I was 45-47. I finally got glasses with progressive lenses about 2 years ago when I was ~50 because it's easier than taking readers on and off. Just wear the damn things all of the time and see everything.

I realized that I like the lightest weight glasses that I can find. Rodenstock makes the Porsche Design glasses, and they also make some super light titanium frames, so that's what I've got.
