The placement of the magnification portion of the lenses on these glasses is pretty low, and some reviewers don't like that geometry because it forces them to look down through the bottom part of the safety glass lenses to use the magnification. For me, that is not a bad thing but a very good, comfortable and useful thing. I try to be very careful about my eyes, and I used to get really sick and tired of constantly removing and replacing reading glasses with safety glasses in the shop. Bifocal safety glasses are a great idea, but I always hated that the reading glass portion of my other brands of bifocal safety glasses seem to take up so much of the upper part of the lens that I couldn't focus properly through the windowpane part of the lens. I seemed to always be consciously looking over the top of the bifocal portion of the lenses, and this effort to continuously focus and refocus was sometimes unsafe in some operations, and it often gave me a headache. At times like that, I wound back up in the mode of shuffling glasses off and on as needed, which tends to accumulate dust and scratches on the lenses and despite my interest in working safely, it sometimes can lead to performing some minor operations without eye protection. These glasses are a great compromise, because I can just put them on, nice and clean, as I walk through the door and leave them on at all times as I move around and work in the shop with normal vision. I can use the magnification when I need it. For full-time close work, I just wear reading glasses or magnification goggles.

Very light, comfortable, and easy to forget you have them on! No more switching between safety glasses and readers to make measurements while woodworking. A great value.
Fastcaps Bi focal line is low...

Fastcaps Bi focal line is low compared to a 3m pair that I am replacing and that is a good thing! In construction getting up and down ladders, stairs, looking at the ground, the 3m pair with its higher bi focal line gives you an out of focus view when tilting your head down which always takes getting used to everytime you put them on. With the Fastcap pairs lower bi focal line, they are very easy to work with getting around and when it comes time to read a print etc., a slight tilt of the head and it's there in focus.The 3m pair is now strictly for the shop and the Fastcap pair is for everywhere else.
