Customer Reviews & Comments
I've never seen bifocal safety glasses before and liked the idea. It was a huge shock to glance at the tape measure and be able to read it without straining. They work great. My only issue is that, in my opinion, the magnified portion could be a little smaller. When in use, I find myself trying to slide them down slightly so that I'm not looking through the line between the magnified and clear sections when doing anything else besides reading.
