Testing visual acuity is a key part of any comprehensive eye examination. Computerized systems improve the classic eye chart as they provide a means to precisely calibrate the chart size, isolate lines, and randomize the optotypes. However, these improvements often come at the expense of full computer system, with all the configuration, maintenance and IT support which that entails.
We offer an alternative for visual acuity testing, the VisionSys-EM. The VisionSys-EM displays to an standard High Definition LED monitor and works well in standard 20 ft lanes as well as short lanes and mirror setups. The system boots directly to the EyeChart program, providing an instant-on capability and a simple reliable interface.

The short story:
Harvest Digital LLC is a small business, founded in 2013, and dedicated to the application of technology to simplify acuity testing.
The back story:

It shouldn't, and I set out to work up something a little simpler for him based on a 10" android tablet.
That product evolved a few times and is now the
VisionSys-EM, which couples a small embedded processor to
a high-definition LCD display. It includes a rich chart
set for acuity testing and capability for video and image
playback, while keeping the focus on a simple intuitive
