Sine Wave Grating

Sine Wave Grating Contrast is standard in Smart System 2020. Following the ANSI and ISO specification for contrast testing and calibrated to the FDA guidelines for luminance levels, the Smart System® follows a simple screening protocol to allow for efficient testing of the contrast function. 

Presenting spatial frequencies of 18, 12, 6, 3 and 1.5 Cycles/Degree with Contrast levels from 100% - 0.8% this easy to administer test provides a great method for monitoring CSF, whether to monitor cataracts or assess quality of vision. Can be integrated with Glare Testing.

Key Features

  • Utilize automated protocol that provides results with normative data or can manually test patients using the M&S Remote Control or Keypad
  • Measure contrast at ANSI Standard 18, 12, 6, 3 and 1.5 Cycles/Degree from 100% to 0.8% contrast
  • Normative data study conducted in 2010 by Illinois College of Optometry.
  • All targets are precisely sized according to the testing distance for maximum accuracy
  • Test in under 5 minutes
  • Perfect for monitoring progression of cataracts and assessing quality of vision
  • At the end of the testing algorithm, we display a graph comparing your patient’s results to normative data

    • Since 1992, M&S® Technologies has served eye care professionals.
