Vision Sys-Em

Vision Sys-EM Digital Acuity System

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.
