Thanks for watching. Dave ; )
Also you forgot to say that as the magnification increases so the actual depth of field decreases. On the lower magnification more of what you view is in focus. The higher the magnificence the more you have to move the item backwards and forwards to get it in focus.
Hi Andrew!, Yes indeed. A very good point, Thanks for that.
The higher the "Magnification". It's just like a camera, there is less in focus. See you at Birmingham. Dave

Thanks you so much I bought loups and items on the internet and no good, but came across your video and your spot on with the Donegan Optivisor review, I also came across a supplier here in Ireland, now I am sure there are other suppliers, but the supplier in Ireland gives Ref numbers for all yours from the 20" to the 4" again thanks for the tips and I am buying one right now and your review is excellent. Cheers from Kildare Ireland Happy New Year 2022.
Glad I could help! Dave
This is an excellent evaluation and opinion piece on the OPTIVISOR by Donegan. It is very well assembled and understandable to folks looks for magnification with their vision. Dave, good job.
Thanks for watching. Dave
I took your advice and bought a pair of Optivisors. After using cheap plastic knock-offs, the clarity and optical quality of these are exceptional! And, unlike the cheap versions...they adjust securely and stay comfortable for hours of carefree use. Since I fuss over polishing so much, I bought the 2.75X (nr. 7), and I think these will help get the results I want in my work. Thanks again for the recommendation!
Thanks for sharing your comments. The glass lenses are brilliant, as you say. Thanks. Dave
Just checking in after buying the Optivisor's on Dave's recommendation. My prior pair were cheap knockoffs--3.5X, but I bought the Optivisor #7 (2.75X). Here's something I ddin't expect--the glass Optivisor lenses at just 2.75X allow me to see much more detail than the cheap pair at higher magnification. I guess I shouldn't be surprised, but I still am--because it's so noticeable, and I get better depth of field as well. Like Dave says in the video--you'll see how important quality optics are.
Likewise. You'd be forgiven for thinking tat 1.5X or 2x magnification wont make a difference, but as you've confirmed it makes a HUGE difference !. Well worth it. Thanks for sharing your experiences. Dave
Note too that as with a camera lens, the lower magnifications have greater depth of field, the higher magnification less DOF. Dave
I haven't bought them yet but wanted to thank you for this and for the lovely bird song!
Thanks. If you haven't seen it, check part out this video to see the culprit.... Dave ruclips.net/video/bf0DPhzy7S4/видео.html
I wondered where the bird song was coming from as my windows onto the garden are shut at the moment!!
I have several knock-offs of this design I got for cheap, but the downside is they aren't made to last. The construction and optics of Optivisor look excellent. I know that buying a good tool once vs. buying ten cheaper tools over a decade is a better use of my money. Great video--I'll consider this brand next time I break a cheap knock-off.
The first Optivisor you see me wearing, with the loupe on, is probably older than me. Still perfect. Dave
True about "all" kinds of head magnifier thingies. They seem to have lots of flaws. What pizzez me off most, is the moving parts wear out faaast, so whatever you adjust won't stay in place. I repair/remake everything, so not a huge problem, but I'd prefere to have been able to afford quality from the start every time.
I looked into these and found the price was significantly higher than other brands. But I knew these were the best and I splurged, because like you said, if you can't see then how can you do good work? I never regret spending extra to get quality tools, and these are perfect. Thanks for the review 😀
The key phrase here is "other brands" there are lot of cheap copies out there, but I allays swear by the originals. Dave
Hi, I bought the Nr-3 & Nr-4 optivisors.
1-I used the Nr-3 with my metal lathe, and found that if I use it without my glasses its more than perfect with distance and magnification, I am a very happy man. With the glasses I probaly will get away with a Nr-2 optivisor.
2-The Nr-4 I think will work with me grinding toolbits for the lathe on a bench grinder also without glasses, my head can go nearer here, or this may work for my wife knitting. I must still prove this.
Ok, my wife chosen the Nr-4 for knitting machine, very happy.
Years ago I got a cheap one with plastic glasses, looks similar, and it was rubbish from the start, I cant even find it.
Thanks for your info.
I use mine all the time, absolutely love them. Thanks for watching. Dave
Got it and never let it go! Good day to you
Me too, always on my head. Thanks for watching. Dave
Excellent info. I almost bought the cheap Chinese knock-offs on Ebay, but after watching your video, I know to get the Donegan brand. Also, I didn't know the difference between the Optivisor and the Optivisor AL. As you pointed out, the Optivisor has the blue precision optical glass whereas the Optivisor AL (LX) uses a slightly lower quality of lens (plastic). I think the AL designation stands for Acrylic Lens.
Yes, I believe you're correct. The AL seem to have acrylic lenses. I'm sure they are great quality, but it kind of misses the point to me. If you're going to get one, get the best, IE the glass lenses. After all your eyesight is very precious. Thanks for watching.Dave
Thank you ole boy. Great review.
Glad you enjoyed it. Dave
Are these mostly to add magnification for people who wear glasses? If one doesn't wear glasses would a pair of reading glasses with 2.5X work just as good for magnification? Thank you for showing the Optivisor.
Doesn't matter if you wear glasses or not, they add magnification, either to bare eyes, or eyes with glasses. Dave
Thank you.@@CelticDreamsCoUk
Thanks for this info
Thanks for watching. Dave
Thanks for this info.
You're welcome. Dave
What Mag should I get for soldering tiny SMD's? They are 8 pin about 7mm x 5mm (very small)
The higher the magnification, the closer to your face. For most jobs I use 2.5X (Number 5) which focuses at around 8" Dave
Thank you for this!
Thanks for watching. Dave
I have one of those that I bought about 25-30 years ago. I’m looking for the a #5 magnifying glass. Hey are great.
To buy the lenses alone can be very expensive. Look on eBay. Dave
For the type of work I do I was advised to buy Quote" Lens 3x-4x magnification, ability to adjust so they'll match eye distance. I also use reading glasses is this for me? What Donegan optivisor should I buy ? Da ? Thanks
The highest magnification Optivisor is the DA-10 which is 3.5 X magnification. But this focuses at 4 inches, so it really depends on what you are doing. Note the table here www.doneganoptical.com/products/optivisor Dave
Rule #1: Do not buy it unless it's a genuine Optivisor. On a side note, when I was a "young buck" apprentice tool and die maker, I used to laugh at the old dudes that had to wear these. Well, now I'm the old dude and have to wear one, and I'm no longer laughing. I've had my (numerous) Optivisors for over 25 years...and they're absolutely amazing.
Ha. I hear you. I swear I've walked into the shower wearing it!. Dave
The loupe adds magnification or multiply the magnification?
The loupe gives more magnification. good for looking at hallmarks. Dave
Those things are cool when you're working
Thanks for watching. Dave
is that good for watchmaking work ?
Certainly, anything where you need magnification. I simply cant work without them. Dave
are usable also with glasses? thanks!
Yes. Dave
working on guitars i use a 2x
Thanks for watching. Dave
Wouldn't be without one
More so as I get older. Dave
thanks but I think I will cope without them they may be good but I can't afford them :)
Presumably you're younger than me. At 50 I now can't manage without them. But when you do need them, the Optivisor is the way to go. Regularly come up on ebay, quite cheaply. Dave
Celtic Dreams LoL you are a young puppy 😎 😇
I'm 58 need 1.5 lenses to see when I'm TIG welding. but use 2 when I'm making chains
