Even if they are good optically, 25X would have problems- that is an extreme closeup.  You would have very poor depth of field and most fingers cannot work at that magnification.  Now, I didn't look at what other magnifications are included, and it might be useful for working at a much lower magnification and just use the 25X setting to inspect the work, then resort back to the lower power for further work.  I'd say most folks cannot actually work on stuff with much more than 3 to 5 power without micro-manipulators.  But allowing a close inspection does have its uses.

Interesting tool. One thing that would be critical to know would be the focal length. It's the one thing I sort of dislike about my Optivisor. The f is about 10".

Just to add a tidbit of info to Don's good advice, I have the strongest lens plate for my Optivisor and it is 3 1/2x magnification.

That said, and I have it on almost always at the bench, I wouldn't want more magnification.

My optivisor has a #4 plate which is 2X. That's enough for me. The biggest benefit is that I can use it over my corrective glasses, which I wear full time.

I also use the #4 plate on my optivisor.  I find it meets my needs and works find with my corrective glasses.  I have tried the higher magnifications, but my hands and eyes could not coordinate properly and I was always knocking things off the model.

I have not used these, but they look pretty good. Not sure if I would use the 25X magnification.

I have several pair of glasses +2.0, +3.0, +5.0 and +6.0. I haven't needed to use the 6.0's yet.

Even the 10X magnifier that they show would be a bit much for me.  I sometimes find the 4X optivisor that I use is too much at times.  I agree that the focal point is also a consideration.  I would not want to work an inch or two from my project.

Steve5,

I just found these on Amazon for $10.89 with Prime.

Check it out here

Check the reviews, most are saying what was said here already. The magnification is so high that you have to hold the object to close to the glasses that you are not able to use both lens at once. However, a couple people say it's somewhat effective if used like a monocle.

I forget the magnification conversion, but I believe the result would roughly be somewhat less tha 2".

Hi,

After seeing the post about them being available on Amazon Prime for $11, I went ahead and decided to order a pair, since 11$ didn't seem too overly expensive.

They arrived today, and I was surprised that for just $11, the lenses seem to be of a reasonable quality.  Overall the box describes them as Watch Repair Glasses, and they seem like they would be quite useful for something like that, or of similar detail.  The came with 4 sets of interchangeable lenses (10x, 15x, 20x & 25x), and most of them are very much for extreme closeup work.  The also come with a strap that, if I am understanding correctly, you can swap out with the ear frame pieces, so that you won't have to worry about them sliiping off your head.

With the 10x lenses in them, as Don has noted, the focal length seems to be right about 2inches or so.  As such, I probably wouldn't use these glasses for most work, but maybe for some really detailed small photoetch assemblies or such, that look like that will probably be a nice addition to my model work station.

I have two Optivisors, a 4 and a 7. Years ago the 4 was all I needed, now at times I rely on the 7. I need help only for close work, this arrangement does the trick for me.

Using the 7 without reading glasses on, I find it gives me a focal range of 4 to 7+ inches. I tried glasses similar to those shown in this post, my dentist uses them and they have a central LED light. I found them limited in function as the dual lenses make for difficulty in doing the finer detail work, focusing usually ended up using them as a monocle.

Overall, I recommend the Optivisor as most useful.

Not those but i saw this today while looking for something else

https://www.princessauto.com/en/detail/watch-repair-magnifier-kit/A-p8686719e

so reading the reviews and the limited movement in my arms these would not work for me

Gents, I wear tri-focals since my vision has gotten not great with age. I picked up a very cheap optivisor from Harbor Freight several years ago and they are my "go to" tool for me. It has a stationary lens and a hinged one, most of the time I use both lenses and can wear my glasses at the same time. They are very comfortable and are just fantastic. It also has a small round lens for extreme close ups. I use this small lens to help remove splinters from my fingers.

I like it so much that I picked up a spare one on sale for $4 a while back.

I've used the Optivisor but found the strap uncomfortable. I would much prefer something that wasn't hard plastic. So I gave these a try: https://smile.amazon.com/gp/product/B01H8808H6/ref=oh_aui_detailpage_o04_s01?ie=UTF8&psc=1

They are the most uncomfortable things I have ever used for anything. The nosepiece digs into your nose and they're heavy as all get-out.

I think, until I can find an Optivisor with an elastic or velcro headband, I'll just stick with my Dollar Store reading glasses. They've servied me well for several years now.

I was on our version of Craig’s list called "kijiji" when I saw an Optivisor for sale, I was just at my LHS the week before, and saw 1 for $39.99 + taxes, so the add had this one for $10.00, I could not get my wheelchair out the door fast enough to get to the meet. The padding was clean and in great shape, no old sweat order, and the Velcro was crisp and grippy. Saving $30.00 always puts a smile on my face!
