For subjective refractions, Hongdee’s manual phoropter offers a full suite of spherical, cylindrical, and prism lenses in a compact housing. Its smooth, gear-driven lens wheels ensure precise power selection, while the stable mounting frame attaches to most refraction desks. U can combine this with an auto refractometer for quick starting points, then refine manually.
- Smooth dial operation: Clickless rotary mechanisms for quick power changes.
- High-quality optics: Achromatic lenses for minimized aberrations.
- Ergonomic design: Adjustable forehead for patient comfort.
