When working with small objects, we try to get closer to see more detail. Bending over in an unnatural position for extended periods of time can result in eye strain and back pain that can have long-term, detrimental consequences on our overall health and well-being. Using surgical loupes quickly improves vision and corrects poor posture.

The double-hinge design of these loupes allows fine adjustments for the perfect positioning of the optical pieces in front of the eye. The  flip-up feature allows quick switching between normal and magnified view.
