DaytonTM AVT

HFR introduces the most advanced vision testing instrument for your clinical and research needs.

Dayton AVT was developed in collaboration with the US Air Force Operational Based Vision Assessment (OBVA) laboratory to support new demands in vision testing for the USAF aircrew members. It crystalizes years of vision test development by the USAF vision scientists in a single multifunctional instrument.

  • Fully automated operation
  • Pre-programmed and custom exam protocols
  • Comprehensive assessment of visual function
  • Three testing distances
  • Accurate threshold based testing
  • NIST traceable factory calibration
  • Self calibration function
