It has 3 different magnification levels you can choose by removing the glasses screws. The level with the most magnification requires you to place the object few centimeters away from the glasses, the middle one requires like 15 cms. and the one with the lowest magnification (it is still good magnification) requires you to view the object like 30 cms. away.
It is a good buy if you need precision to work with in a workshop or maybe when sewing.
I recommend it!
Each magnification glass can be removed. I recommend using only 1 at a time and storing the other one as a replacement.
