1 Large display range for pupil distance scale

2 Easy Locking with Proximity Rod

The columnar shape gives the VT-50 a more appealing aesthetic, while allowing you to lock the torque with less effort. Our phoropter is easy to lock with the proximity rod.

3 Get more accurate measurements of astigmatism and axis position.

VT-50 Get more accurate measurements of astigmatism and axis position.

4 Prismatic paddle wheel is more convenient to turn. VT-50 prismatic paddle wheel has no sharp edges to cut your fingers.

There is a large spacing between the prism and the crossed prism,

which gives room for your hand to  fit and turn the wheel with ease.

5 Attention to detail increases refraction accuracy

The VT-50 has threads on the inner wall of the aperture hole to prevent reflection and increase refraction accuracy

6 The key gears of the exterior mirror are copper

The key gear components of the VT-50 exterior mirror are metal copper, and the other plants are plastic or steel.

 7 Backshell gear parts made of metal.

VT-50 backshells with all metal parts and pure copper for key gear components.

Other factories use plastic and stainless steel parts.

8 Cross-frame section with brass fittings

VT-50 cross frame part is made of pure brass fittings, other factories use iron fittings with painted appearance.

 The VT-50 pupil distance phoroptor rotates one turn and the pupil distance mark moves a distance of 6mm, the other pupil distance phoroptor rotate one turn and the pupil distance mark moves a distance of 2mm.
