NSKI 3.5X420mm Binocular Plastic Clip Loupes DY-110 Lab Head Magnifier w/Clip-on

I previously paid over between $950-1500 for professional dental loupes which were fixed onto glasses permanently and expensive and unfeasible to change everytime my prescription changed. These are a bit heavy but grip well onto any of my frames, fairly easy to adjust and stay on well with the provided strap. I got the 3.5 magnification and for dentistry this let's me see almost a whole arch with a working distance of about 14 inches. Pretty good for $40 bucks! The center adjustment works but the lenses are at a fixed angle but are in a good spot. Binocular function is spot on, Happy customer. Wish they came with protective lens caps, box is nice.

These are too heavy to be held up with just glasses and the magnification is closer to 1.5 to 2x and definitely not 3.5x. also, they're printed with a 420mm working distance but its closer to 300mm

In short, I can see with these goggles bright, crisp detail of small items on my lap that I otherwise would have to hold at close sniffing distance to see. Depth of field is adequate and not fidgety. Field of view is about a 3" circle. Center of view can be adjusted finely to your liking. So far so good, and I am reasonably impressed with the good functionality for the low price.What's not so great is fiddling everything back into place on your glasses frame and readjusting the precise aim and fit that got bumped minutely the last time you set them down. Not that this is difficult, but bear in mind that the details viewed are not notably better than just holding things to your nose to examine, as you maybe had been doing all your life.I will note in closing that I had been clipping my toenails mostly by feel for at least the past decade. I am happy to report that I can now at long last see my toes in excruciating clarity. I look forward to my next pedicure. Aside from that, I'm not at all sure what good use I'll find for these goggles, as good as they are.

I have been a dentist for 35 years. I currently have a set of Surgitel loupes that are 20 years old or so and on its last legs. I bought these instead of spending $1500 or so and am using them as I write for the first time. They are great. I did 6 surgical extractions so far today and some complex restorations. The clarity and magnification are spot on. I am going to buy another unit as a backup.Jim Bradford,DDS

The magnifiers look okay but the whole bracket is flimsy, and cheaply built. The screw on top for sideways adjustment is useless since the two rails slide by lightly pushing it.Save the money for the fancy box and make a more robust product.I returned it.

They clip to my glasses so well, they are a little heavy so you have to pull the head strap tight.I do wish I could hook a light to it.

Nice magnification and great adjustability but it's very heavy to put on my glasses. Glasses keep falling down.

These work really great, but they are so heavy I had to by a strap to keep them on my glasses on my head with these on them. It is VERY nice to get a close up view from over a foot away from the object, instead of right next to my face.
