I'll have to try the blue light blocking lenses. My progressive computer glasses live at the computer; there's a case there that holds my regular glasses when I switch. Never thought to deduct them, but they are right at my work-only computer and it's the only place I use them.
I've found that with focus at computer distance they're fine to answer the door, fetch in the mail, talk to a client etc - they're all just a little fuzzy. I'd only try to drive in them if my regular glasses got crushed, though! And it would be straight to the eyeglasses store for replacements.
