Zenni optical has been fine for regular glasses, but I"d like to get
safety glasses with side shields for the shop. I emailed them
inquiring whether they sold safety glasses / frames, but got no reply.
Is there any place where you can get inexpensive safety glasses with
bifocals?

I have a pair of Crews bifocals, but it looks like they're only making
full lens magnifiers now. I actually prefer a full lens for most
things in the shop, but I use a relatively mild +1.50. Moving around
might be problematic with a stronger lens.

I'm not familiar with Crews -- do you have a URL?
