Additional Features:

Design and Build: Constructed with corrosion-resistant materials and no plastic components for durability. Bi-loupe turret in a single plane for a wider overlapping field of view during testing. Concentric cylinder power and axis controls for easier, more accurate operation. Synchronized cross-cylinder measurement for faster results with reduced error. Optically additive lenses, allowing practitioners to add powers together to achieve effective power.

Ergonomics and Usability: Known for its smooth dial rotation, minimal mechanism play, and precise, solid control knob clicks.Face shields can be washed, soaked in alcohol, or boiled for sterility.

Applications: Used for comprehensive eye exams to assess visual acuity, refractive errors (myopia, hyperopia, astigmatism), and binocular vision.Suitable for various clinical settings, including mobile eye clinics and outreach programs due to its sturdy, portable design.
