These binocular magnifying loupes easily clip on a pair of glasses (glasses not provided). The pupillary distance can be adjusted with the central adjustment knob. The double hinge design allows vertical adjustments in front of the glasses so that the optical pieces can be positioned perfectly in front of the eye. Switching between magnified and normal view is possible by flipping up the loupes.
