For detailed subjective refraction beyond phoropter limits, Hongdee’s trial lens set and frame provide a full complement of lenses and prisms. The adjustable frame ensures stable lens positioning, while the complete lens box includes specialized diagnostic lenses (e.g., Maddox rod, polarized). U can conduct cross-cylinder tests, cover tests, and binocular balancing with ease.
- Comprehensive range: All common lens powers and prisms included.
- Quality materials: Lightweight alloy frame and scratch-resistant lenses.
- Ergonomic adjustments: Nose pad, temple length, and tube tilt adjustments for patient comfort.
