I have owned an OptiVisor for several years. Originally purchased for work, I bought a second pair for home and have used them for (to name a few) pulling splinters out of the kids fingers, assessment of a problem with my dog's paw, detailed gluing of small project work, removing and assessing a tick, replacing a watch battery and for making small, detailed measurements. My eyes aren't what they used to be--but with these... they're temporarily much, much better!
Others have reviewed the limited depth of field. This is true--you'll need to be close to the subject for it to be in focus. Please understand that this is not a fault of the manufacturer but is the way optics perform when designed to work in this fashion. In my opinion, this limitation makes these an unsuitable solution for reading unless you need extreme help and are willing to hold the material very close. I've tried. It's clumsy.
Two notes from my years of using this product. 1) There are "thumbturn" tighteners (small knobs visible in the picture) that keep the visor in position once you've adjusted it on your head. We tend to only tighten the one on the right because we are right handed. The left one became loose, fell off, and was lost for quite some time before we located it under the couch. Keep both of these finger-tight or you may lose one of them. 2) The optics can scratch if you store the visor improperly. We like the visor so much that we put a hook on the wall near the office desk--just an arm's reach away. Easy access. Safe storage.
These are ruggedly built, well-designed and have helped me to solve many problems. Therefore, they get my 5-star approval and recommendation.

I been using this product for years and years, 1 have 2 broken ones where the plastic hood part cracks and is impossible to glue back together.
but is light weight and I can wear them all day working on electronic circuit boards.
There are many magifications of this product but this one a #5 is just right gives you about 7-8 inches away from work area

I bought this headband magnifier to be able to work hands-free on electronic circuitry and small surface mount components. I thought I'd be able to use a small soldering iron while wearing the visor, but at the point of good focus there's only about 3 to 4 inches of clearance between the lenses and the work. It can still be done, but you have to be careful as you bring the iron in and out of the working view so you don't burn the visor or the lenses.

This magnifier is good overall. The fit is nice and snug and pretty comfortable to wear for extended time. The lenses are good quality, although if I had to buy another I'd get a lower magnification than this 3-1/2X. It's very hard to work with items because the focal length is under 4 inches. The 2.5X or 2.75X are probably better for getting more working distance. The knob-adjust headband is a nice feature for quickly adjusting to a snug fit, and the side knobs let you adjust the up/down swing very easily.

I also ordered the OptiLoupe 2.5X addon, but that thing is pretty useless. It's very hard to use and it has a narrow zone of vision.

Overall, the construction and quality of this headband visor is very good and it does what it claims.
It costs a bit more than most others, but it seems to be of very good construction.

These are everywhere and can be found at low prices if you look around, which you should because these are the most form-fitting, all-day wearable magnifiers of the bunch. Not fancy, not a lot of features, and not much weight, which is very important if you plan on actually using this type of head worn magnifier for extended periods. The lens material is very scratch resistant, easy to clean, and clear. The adjustable headband is simple and not fancy at all, but it conforms to your head, unlike the very uncomfortable B&Ls, which I also have.

I bought my last pair of these for less than I see here on Amazon, where I think they are priced a little high. Even so, these are the ones to get, because the design is superior.

Donegan 3 1/2X OptiVisor Headband Magnifier I purchased this product to work with building my PC. Not knowing that '3 1/2X' this magnification would only occur at 4 inches from the object, it does not meet my need for image clarity. To help other customers with my same perception, the description for these product items should clearly state the focal distance which will take effect during use.

Comfortable adjustable headband, and a good magnification level for most tasks I run into. I've used it for small electronics work, pulling splinters, etc.

Great product and as described with Glass lenses mounted in a green plastic frame, this is not the cheaper LX model Optivisor that has lenses ground from clear plastic mounted in a clear plastic frame. I have been using Optivisors for over 20 years, this is the real professional DA-7 Optivisor with glass lenses.

I'm a pathologist who, like most pathologists in clinical practice, frequently examines (grosses) small (1 to 3 mm) biopsy specimens. I've used Donegan's OptiVISOR for grossing for quite a while. I have the 3 and 4 diopter lenses. As my eyes get older (I'm 70) I rely on it more and more. Histotechnologists who embed biopsy specimens also need the OptiVISOR. (Amazon offers two competing products - I've never seen either of them.)

This gadget performs as advertised. It magnifies and allows you to see objects in details that are normally very hard to see. However, in order to focus on the object, you have to keep the object close (6 inches). For lower power optivisor, the focal length is longer and you can keep the object farther from the eyes. It does allow me to wear my eye glasses, which is a plus. Beware that the lens are made of acrylic instead of glass, as mis-stated in the product description. Though the acrylic is lighter in weight, it is easier to scratch so I have to store it in the box to protect it.

Pretty good item. Purchased the 2.5x magnification, which has a focal length of 8". So far so good, but I do wish the focal length was a little further as I dont think you can even get the full 8" away. Fairly comfortable. At this focal length you almost should have a built in light since you're so close. But, I do like the item and have no regrets of buying it. Thought adding the light will bring the price up quite a bit. Feels like quality construction as well.
