Another advantage with the 'stick-on' bifocals is that you can
carefully trim them to make them narrow in width (about 60% of
their original width), thus preserving the ability to look
'outside and down' without their intrusion.

I used them for several years on Serengeti sunglasses and liked them,
but switched to the Sunreaders when I discovered those even better
because they were untinted in the bifocal area, and because the stick-on
bifocals introduced some glare when the sun hit that area. I think the
two extra surfaces between the sunglasses and bifocals caused it;
nonetheless, they can be a good solution for people with prescription
sunglasses. At ~$20, they are cheap to try, and cutting them down as Jim
suggests is a good idea. You can probably get them to stick better, and
reduce the glare I got.
