1 Easy Locking with Proximity Rod


The columnar shape gives the VT-80 a more appealing aesthetic, while allowing you to lock the torque with less effort.



2 Get more accurate measurements of astigmatism and axis position.


3 Prismatic paddle wheel is more convenient to turn.


Our 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.



4 Attention to detail to increase the accuracy of optometry.


We pay attention to details to ensure the accuracy of your readings. The threads on the inside of the window hole prevent reflections which can negatively affect your readings.


5 Traceability Marking


The VT-80’s casing comes marked to allow for easier assembly.


6 Front case gears are made of metal.


The VT-80 uses high quality metal gear parts for all of its front housing components. This allows the VT-80 to withstand the wear and tear of time.


7 Backshell gear parts made of metal.


The VT-80 uses high quality metal gear parts for all of its backshell gear parts as well. harder and longer life.
