Zgood 3.5X 420mm Loupes Surgical Binocular Loupe Dental Magnifier (Black)

My initial impression was that it was too low a price for such a good product. I was very surprised when I opened the nicely made, rounded box. When I took them out of the hard zipper case, I found a beautifully finished product the optical quality is good the case is quite strong and when I adjusted them for magnification, I found the result to be even more amazing My needs are met to an extent that is beyond adequate. To those who don't know much about optical magnifying, here are a few words of caution. To achieve binocularity, the correct adjustment must be made. In the event that they are a tiny bit too wide or too narrow, you might be seeing out of one lens or possibly experiencing In order to see each lens clearly, their spacing should be close to the distance between your pupils at close range. A simple ruler can be used to measure the distance between the pupils, whether you are wearing eyeglasses, going to your eye doctor or measuring it yourself. Having done this, the lenses must then be angled in such a way that they point roughly toward the focal distance (in this case, You should rest as close as possible to the spectacle lens behind the lenses on the back of the glasses. The only disappointment is when I realized that this camera is a little shorter than the 420mm focal length and that the depth of field is not nearly as large as I would like (Depth of field in photography simply refers to how clearly the subject remains in focus from close to far). The nose pad is quite comfortable, so even though some users have complained that it is heavy, I haven't found it to be problematic for short projects. A diopter range of 50 to 100 In general, I am happy with this product and would buy it again without hesitation.

It's for assembling electronic circuits that I got these. Reading is something I usually do with glasses. Compared with my prescription glasses and with a pair of two, I found this product to be superior. A total of five $15 reading glasses are available off the rack. Aside from being small, a bit darker, and out of focus as well as being uncomfortable, the image area is very narrow. My afternoon with them was brief, and I did not succeed in getting It was today that I returned them. Using reading glasses during assembly is fine, although you might want to use a magnifier to check solder joints closer. Cheap readers in different magnifications will be more comfortable and clearer if you don't wear reading glasses or don't wish to wear them at all.

For students just starting school and in need of some cheap loupes to get used to the idea, I highly recommend these.

This is a great product, I use it a lot when doing fillings, and I recommend it for what it is worth.

In opposition to what the manual suggests, I found I needed to adjust the "toe in" of the loupes when I changed interocular* That ended up working much better to eliminate double-views. I have a horrible eye condition, but getting a clear focus by simply adjusting workpiece distance by eye allows good focus. Getting everything right the first time is difficult, but once adjusted it has remained stable.
