Mercifully my vision at any distance over about 4 feet is still excellent. I only need glasses for the up close stuff. I will check out the other suggested sites though. I appreciate the assistance y'all are giving me!
I have polarized prescription bifocals (both clear and sunglasses. Sunglasses are good in the van and on the bike. I wish the division between top and bottom prescriptions was a little bit lower on the lens, but I just let the glasses slide a little south on my nose and everything's fine. We'll ask for that next time.
I've noticed that the LCD screen (on the bike) is just a little bit dark with them on, but it's just about black if I have the visor down as well... Not sure if the visor is adding a polarizing effect as well, or if it's just some weird unexplained (to me anyway) phenomenon...
I usually ride with the visor halfway open anyway, so it's never been a real problem, just a nuisance sometimes...

For the GPS I think I am going to get a couple of welder's magnifying lens and attach them to the bottom of my visor.
You might want to try the Optix large I just mentioned if you plan on adding to the visor. They are more expensive, but how would you attached a solid, non-curved, welder's magnifying lens insert onto a shield?
Duct tape. Neatly applied, of course, because 'Nothing screams bad craftsmanship like wrinkles in your duct tape!'.
I cut the lenses up as needed and then just use something like a dab of hot- glue or silicone seal to keep them in place.
I have a pair of Ray-Bans with no line progressive lenses. I bought them here: http://www.readingglasses.com/search/?searchinput=&sorting=0&cat_id=_1000113&view=0

What is that in reply to?
They also have Maui Jim's with bifocal lenses.
I've been wearing bifocal sunglasses / safety glasses for over 10 years, we used to have a COG member that had a site called sunglasses guy, but I can't find him, I bought 4 sets of those wraparound style units, that came with clear and dark bifocal lenses and 3 other shades, including amber night lenses, for about $20 delivered... well, they cost more now, as the demand seems higher...
quick google gave me these tho,

still, you can get what ya need..
personally I think paying $100 for a pair of glasses that don't come from an eye doctor is ridiculous... it's all in the name they carry, and if you drop them, or sit on them, you're out $100.... silly.
The best reading glasses I have cost $19, and I have progressive "Lacoste" framed main working glasses I paid $400 for from my eyedoctor, that really don't compare to the el-cheepo's... go figger'
just to note, I originally went in search of these when I was on the way home from a ride, and had to read maps on my tank bag map holder, so I was wearing mini reading glasses down low on my nose inside my helmet... well, after an hour in bright sun, scanning the map, and looking over the tops while riding, I realized the reading glasses were focusing the sun glare off the plastic on the map cover directly to my retina's... and the resulting sunburn and UV welding burn was obvious....
ouch...
no more of that nonsense, and unfortunately my progressive reading glasses (no mag on top, some mag in middle for computer screen distance, and lateral scanning, and high mag on bottom) simply recreate the intense retinal burn...
takes a few miles to get used to the bifocal sunglasses, but when you get them right, and simple scan down with the eyes to see the gps, it works really well.. oh, and refrain from the polarized ones... most modern helmet shields are polarized, and my helmet has a flip down internal tinted "aviator style" insert, which doubles the polarized effect... they don't mix with polarized glasses at all...
ymmv
One of the first safety tips I picked up about 40 years ago was not to wear polarized sunglasses on a motorcycle. It was said that the glare caused by oil or grease on the road surface could be masked by the polarized glasses resulting in a missed opportunity to avoid a crash.
I've noticed several references to polarized glasses, these are a disaster for me on a motorcycle. Any plastic that's been shaped into a curve has induced stress areas, face shield, windscreen etc and polarized lenses make those areas of stress visible as colors. Engineers use this phenomenon to model structures in plastic and expose them to stress to visualize areas of concentrated stress. I've tried polarized lenses and I can't see through a plastic surface without a rainbow of colors disrupting my vision. Add two layers and it's really disruptive. I use only non-polarized lenses. Results may vary....
I put a strip of very dark tint across the top of it to block direct view of the sun.
