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.

These glasses are very good. In fact I also use them as my riding glasses at night when riding my motorcycle. They allow me to clearly see my speedometer and other gages. (several members of my MC have asked me to get them a couple of pairs also) In the shop they are also good. There is only one bad thing about them and that is that the bi-focal part is too low on the glasses and causes me to have to bend my head back in order to use them. If the bi-focal part was larger and higher on the lens it would be much better and I would order a ton of them if redesigned with the larger bi-focal or raise it on the lens, I would have no problem rating these a solid 5. Still a very good product at a good price. I am pleased with mine (I bought 8 pair so far, as they are made of plastic and do scratch easily and I like clear vision). Good work Rockler for continuing to provide the best products at reasonable prices.

Believe these are a great product idea. They just need some design tweaking to make them excellent. My main issue is that after 2 years or so, the hinge area breaks - while the rest of the product remains fine. The weakest link in this product is in the clear PC lens area of the hinge. If it was made perhaps 50% wider in this area, it may last a lot longer. The black plastic temple remains strong in the hinge area. I hardly ever fold these lenses. The plastic in the hinge area becomes weak from the normal mechanical stress that keeps them on your head.

Nice saftey glasses, but the whole point of purchasing these is the bifocal lense. Anyone that uses these would have to agree that the bi lense is too low.

The lens area is too low in the field of view for machine work as I must tip my head back to see through the lens. Work fine for reading, which tends to be lower, but not when you need correction at mid-level.
