Got the 5 pair of the bifocals in the mail the other day. Took 2 days to arrive. Used them over the weekend (1 pair anyway) They are great. Very light weight and they don't slip off my nose when I'm sweating and hammering. I did notice that they are very close to the face and there is not a lot of ventilation. That's ok in the am when it's cool, but when it's hot it got a bit warm. I just pulled them away from my face by a silly millimeter or so it was fine. They stayed put.

I got one pair for riding and a spare. I also put one pair in each car.

I got one clear set and I'll use them at night and in the workshop. Look forward to getting some other styles soon.
