The MicroLine Flip-Ups are some of the smallest and lightest flip-up loupes. At one third the size and weight of other loupes, these are so comfortable you won't notice you're wearing loupes. PeriOptix's proprietary compact lens design sacrifices nothing but weight. The field of view and image quality are what you'd find in larger and heavier loupes.
