I wound up buying glasses that sold inserts that were already ground to specific diopter values like drug store reading glasses. That worked out okay (I wore them on a coast to coast tour and a bunch of other riding) until I later had some Project Rudys made for me.

In recent years I have been wearing some regular glasses with large lenses that give good coverage and stay up well. The transitions coating has sufficed in lieu of real sunglasses.

At one point I had two identical pairs of avaitor frames one with a dark tint and one clear and I just switched between them depending on the activity and weather.

I may revisit all this when I next get an eye exam if there is a change in my prescription.
