3M Safety Glasses, BX Dual Readers, +1.5, ANSI Z87, Anti-Fog Clear Lens, Gray/Black Frame, Adjustable Length Temples and Lens Angle

3M has done an outstanding job on a specialized product. I wanted to review these as soon as I took them out of the package. They're that good. But I decided to wear them at work first, to make sure they're really all that. They are. Excellent Safety Excellent Diopter Placement Excellent Comfort and Adjustability Excellent Anti-Fog Properties Excellent ValueFirst, some credentials: I'm a welder in my mid forties. I do structural stick, aerospace grade TIG, production MIG, and just about everything else. I have to do machining, print reading, inspection, and report writing on any given day. Near field eyesight is both critical and at risk in this line of work. My near vision has been on the decline for the past five years or so.I'm also OSHA 30, so I have an idea of what goes into safety and worker compliance on a theoretical as well as practical level. And on the practical level, I'm no lily. I spend most of my time in the trenches getting as dirty and busted up as anybody else.So I need excellent eye protection, and I need a diopter. However, ordinary bifocal safety glasses just don't cut it--they're designed to magnify only that which is at desk level, more or less, hence the term "reader". When working at or above eye level, you'd have to tilt your head ridiculously far back to focus. I was delighted to find Jackson's 30.06 style dual segment readers a few years ago, which, like these 3M BX Dual Readers, have a second diopter at the top of the lens. I like Jackson products a lot, and I'd been wearing their safety glasses anyway, so these were perfect...except...they're expensive, hard to find, easily scratched, fog quickly, and, like pretty much any other safety eyewear short of goggles, just don't have adequate coverage.I'd seen the 3M dual readers occasionally when hunting for a deal on the Jacksons, but I recall them being more expensive, and I didn't want to mess with success anyway. The Jacksons are getting harder to find, though, and this time around, the 3Ms listed cheaper, so I thought I'd give them a try. I'm sure glad I did.The 3M dual readers are easily adjustable without being sloppy. The mounts for the temple hinges ratchet away from horizontal to raise or lower where the lenses rest on your face, or to tweak their vertical angle. I cannot believe that the reviewers who criticized the location of the magnifiers noticed this feature. Further, the lower magnifiers are in exactly the same position as three other models I compared them to, Jackson dual readers, regular Jackson safety bifocals, and another pair of safety readers (with no discernible branding left). At first glance, the diopter segments on the 3Ms seemed smaller than the Jacksons, but closer inspection revealed them to be just about the same size. And let's be clear--bifocals are not supposed to magnify objects at eye level; that would defeat the purpose. Yet even with the lower edge of the lenses pushed below my nostrils, I don't have to go through the contortions described by other reviewers to see through them. In addition, the ear pieces extend with a firm detent so that the lenses will hug your face regardless of your head geometry.I can't overemphasize the importance of this close fitment, which results not only from the adjustability of these glasses, but also the shape of the lenses. Together with the brow section of the frame, they provide complete coverage of the eye. I've needed medical attention for at least three eye injuries sustained WHILE WEARING safety glasses. In two of those cases, a metal splinter had to be pulled from where it had penetrated my cornea. In both of those cases, the debris had shot up under the space between the lower lens and my face. I've had that happen with somewhat less serious consequences on many additional occasions, even with the Jacksons, which have better coverage than most safety glasses. The lower edge of the lenses on the 3M dual readers rest comfortably on my face, closing this gap. On the whole, they provide outstanding coverage while remaining low-profile enough to be comfortable under a welding shield. They are, in fact, nearly a chic and stylish as the Jacksons, which have brought compliments when worn a sunglasses (shaded Nemesis model, which are the same size and shape as the Jackson 30.06 dual segment readers).Finally, the 3Ms really don't fog. Really. I have tried all sorts of commercial products as well as folk remedies for foggy lenses, but nothing has worked for safety glasses. On a hot, humid day, they've always fogged up as soon as I put on my welding shield or respirator. Not these. Today was hot and humid here, and the 3Ms stayed crystal clear the entire time I was welding. I have little doubt they'll do as well with a respirator. They'll also take longer to get scratched up, which will help keep them from fogging, as their shape holds the lens up off of any hard flat surface you might inadvertently put them down on.I'll continue to use Jackson products for my other needs. I still consider them to be outstanding. But in this case, I'm glad I was prompted to try the excellent 3M BX Dual Readers. I'll buy them again and again.

Very nice glasses, sturdy, excellent coverage, no distortion that I can see, good adjustability, The nose and temple grips could be softer, but they are all-day comfortable the way they are. The upper bifocal area (my old glasses had just lowers) is absolutely brilliant for reading a tape measure in tight quarters and overhead. I wish both the upper and lower bi-focal areas were a little smaller, as the uncorrected vision area is quite narrow (well, short top to bottom), which leads me to look like a confused dog when trying to look upwards outside of reading distance.The anti-fog feature is much better than nothing, but they will still fog up under certain conditions that I seem to meet a few times a day. I doubt any safety glasses can be truly fog-proof on my sweaty noggin, short of installing a couple 25mm fans in my hat bill. The lenses are very easy to keep clean (using a microfiber cloth), perhaps due to whatever coating 3M applies.Off the job I don't wear bifocals, just readers as needed, with glasses dispersed throughout the house and vehicles. So it takes a little while every morning to remind myself that bifocals can be tricky, especially dismounting the last steps of a ladder, and I spend a lot of time on ladders. If you're like me and don't normally use bifocals, and are old, set in your ways, and maybe a bit dumb, be extra careful to not fall off of ladders and steps.

These up and down glasses are great for me - working on motorcycles, installing cabinets, and the like. BUT, the clear middle part is a very narrow band, so walking around with them on can be pretty disorienting. The down magnification is great with no distribution, but the up magnification makes things seem to move when I rotate my head, which I don't like, of course. The temples are adjustable up and down, and front to back, but are too tight behind my ears, so require modification, not just adjustment.

I have no issue with the dual readers concept as long as I wear them correctly ( at the right height)..my only complaint is that I work in a hot sweaty environment, surrounded by machines and oil vapors in the air… these vapors that I work with are petroleum based and they are hard on plastics…. Whatever the nose piece on these safety glasses are made of falls apart after only a couple of weeks of exposure to the oil and sweat…. Otherwise, they’d be great… my only other gripe is that you need to wear an elastic strap to keep them at the right height to see out of the non magnified section, which is where I spend most of my time.

I use these glasses for doing electrical and carpentry work in barns and old homes, usually while standing on a ladder. Before these glasses, I had to wear reading glasses which did not provide good chip or flying object protection. It was a pain to remove the reading glasses when going up and down the ladder, put them on while drilling or scraping to see the work clearly, and remove them again to go up and down.These glasses have 1.5 diopter reading lenses molded into the top and bottom of the protective glasses. When working above, I can clearly see the work through the top lenses while still having very effective eye protection. The glasses work as regular reading glasses by looking through the bottom lenses. It takes a few minutes of practice to figure out exactly where to look, but the benefit of having everything in focus above and below is well worth the trouble. I can keep these glasses on my face for hours and do all my work, including driving, with ease.

item as described and well packed, SUPER FAST shipping. AA++ seller

El aumento en la parte superior impide la visibilidad lejana. No muy prácticos.

Great lightweight glasses, but not thoughtfully manufactured. I have prescription glasses like these, but they are heavy and in hot weather they are just annoying. So I picked these up and immediately noticed the problem. If I look down to read something, it's maybe a foot away...which I can read. The computers and things I need to look up for at work are further than a foot away (maybe 18-22 inches away).... they are not in focus. So I either have to tilt my head all the way back to see the screen, or constantly lift my glasses to get the screen in focus. So the top bifocal is essentially useless.

Muy buen producto excelente calidad, solo que se raya rápido pero insisto es un muy buen producto
