Really.

Off that site, a cheap pair of frames and lenses is ~$35.00USD
(including shipping!) I can have multiple pairs and if I lose one, no
big deal ... that site certainly looks good to me. As long as the area
of corrected vision is large enough on the lenses--should work fine.
Height of the pupil can be adjusted with adjustment of the nose pieces
or padding.

I don't plan on wearing these glasses to see the king--just for work
where something always happens to 'em!

Ever misplaced a pair of glasses, grabbed your backup and lost them?
Everything stops until at least one set is recovered.
