I recommend!

They do work but fall down on the following:1) Magnification is exaggerated by a factor of two approximately compared to other eye glasses e.g. x20 is more like x9 of other makes. Focal length seems excessive.2) Too small to be held firmly in the eye. They easily fall out unlike my larger eye glasses.3) x20 very distorted view - poor lens dimension quality.4) Won't stack which is useful for storage.

Bit plasticy but functional and not bad for the low price

Ideal for Jewelers and blade sharpening to observe edge geometry and grind marks. Very pleased with the set.

These are ok for £5.99 paid for them. So not the best quality. Find them a bit big to stay in my eyes so will have to add some elastic to go around head to keep them in place. Magnification is also nice and clear on all of them. Just a little bit smaller to see on the 20x magnification one.

Very poor
