Both innovations were developed by STZ eyetrial. They are used to illuminate visual acuity charts and allow standardized conditions for testing of contrast sensitivity and visual acuity. They were inspired by our daily work and out of the necessity, to obtain standardized, comparable and reproducible results.

  • Luvis meets the lighting requirements of EN ISO 8596th.
  • Luvis meets the requirements of FeV enclosure 6.
  • Luvis is illuminated by standard fluorescent tubes that have a daylight spectrum and a very long life.
  • Luvis represents an innovative and simple lighting solution.
