Manual Phoropter

Manual Phoropter: Utilize a big size dial and fully centralised operation to increase operating performance.
Cross cylindrical lens and cylindrical lens coordinates are automatically linked, there is synchronous connectivity between the axial knob and diffuser built-in, and astigmatism may be corrected all at once.
Multiple auxiliary lenses integrated, thorough investigation of visual function
Through a lens with a reduced diameter, the subject of the inspection may see outside. It is simpler, quicker, and has a wider range of vision than big diameter insert testing and looking through the spectacles.
Focus: The optical core axis of the lens was a straight line from the corneal tip, (to the left and right inside the 2mm perspectively) inside 400mm. IPD can focus from 57 to 80mm.

Manual Phoropter

Model:VT-5B
The minimum degree of spherical reading is 0.25D or 0.12D (when using + 0.12D auxiliary lenses or 0.12D lenses), and the range is +26.75D to -29.00D (when using 10.00D lenses).
Range of astigmatism: 0 to -6.00D, with a minimum value of 0.25D or 0.12D. (when using the incidental lens)
0 to -8.00D (when using incidental lens with -2.00D)
Dial for the first axis astigmatism: 0-180°, each interval of 5°
Exchange type (use with astigmatism axis) cross cylinder: 0.25D, also available in 0.50D
Prism that rotates at intervals of 10 to 20 degrees
Adjustment for interpupillary distance: 48mm to 80mm, at intervals of 1mm (with left and right the same)
Adjustment for the front platform is 16mm forward and 16mm back.
Focus: Within 400mm, to the left and right within of 2mm from the corneal tip,The lens’s optical core axis was a straight line. IPD can focus from 57 to 80mm.
How to measure the corneal distance: Use a scale to measure the first 2mm-5mm from the standard platform.
