• Quick & Efficient Testing: The convenient rack design allows for swift flipping and comparison during refraction, significantly reducing patient chair time compared to using individual trial lenses.
• High-Transparency Optics: Crafted with high-quality optical glass, ensuring clear, distortion-free viewing and accurate visual acuity results.
• Clear, Durable Markings: Each lens cavity is permanently engraved with its corresponding value for immediate, easy identification during examinations.
• Ergonomic & Sanitary Design: Features a lightweight, smooth white ABS frame with an extended handle for a comfortable grip. The non-porous, easy-to-clean surface ensures quick sanitization between patients.

Ideal For

Professional optometrists, opticians, ophthalmologists, and optical clinics requiring a reliable, portable, and highly accurate tool for spherical diopter adjustments and subjective refraction.
