Wide range of spherical diopter
Provides a wide range of diopter adjustment from +16.75D to -19.00D, suitable for a variety of vision problems, including high myopia and hyperopia. The minimum reading accuracy can reach 0.12D, ensuring precision.
Flexible cylindrical diopter selection
The cylindrical diopter range is from 0 to -8.00D, and its range can be expanded with auxiliary lenses to adapt to different types of astigmatism correction needs, while providing fine adjustment options to meet personalized visual needs.
Precise astigmatism axial scale
The astigmatism axial scale from 0° to 180°, with 5° steps, helps to accurately measure and correct astigmatism and improve the accuracy of optometry results.
Cross-cylindrical lens design
The reverse cross-cylindrical lens of ±0.25D or ±0.50D is synchronized with the astigmatism axis, providing flexibility and convenience for astigmatism detection, making the testing process more efficient.
Rotating prism function
Supports rotating prism adjustment from 0 to 20△D, 1△D per step, which is very useful for the evaluation of binocular parallax and other stereoscopic vision problems.
