Weighing in at only 36 grams, our elegant and streamlined TTLs (Through-the-Lens), have revolutionized loupes design. The compact lenses sacrifice nothing but weight. The field of view and image quality are what you'll find in much larger and heavier loupes. Lighter, smaller optics mean you can wear your loupes all day in comfort and with less fatigue. Choose your microTTLs on our Adidas Adivista frame or our classically-designed Ultralight titanium. Both options provide great protection and style. Prescription corrective lenses are available.
