Read the details well. The focal distance is about 3cm so these glasses are not good for painting or working on miniatures.
The magnifier I got is 0 in quality. The way to see an item in focus through the lenses is only from 2 cm away, and each lens focus in a different length, so it is impossible to look with both eyes together. The glasses fall from the face, so with one hand you have to hold the glasses, and with the other you have to hold the item close to one of the lenses, and you have no hands to work with. In short, it is good only for children to play with.
