The Metropsis Edition (v2.*) for Clinical Research is the new version of Cambridge Research Systems' visual function assessment suite for macOS. Fully powered by Psykinematix, it is a modular, expandable and configurable testing system suitable for:
  • clinical research,
  • applied vision research,
  • drug trials,
  • screening,
  • sports science,
  • human factors research.
It includes a "Nurse" interface on top of Psykinematix and a remote App for iPad to control and monitor the tests. It also comes with ready-to-use standard clinical tests (visual acuity, spatial and temporal contrast sensitivity, color discrimination, binocular vision, and many more) and can generate PDF reports after each test session.
