Each plate has four random-pattern squares with a circle of pattern elements lying in depth relative to its surround. The depth effect is due to the circle and its surround being printed on opposite sides of the plate. The Frisby Stereo Test has 3 plates allowing for testing stereo acuity disparity as fine as 15 seconds of arc.
  • CRT Card Test Specifically designed for computer operators who require corrective multi-focal eyewear. Card may be placed at different heights and distanced to simulate the complete computer screen. Card is printed two sides -one side shows a computer screen with AOL. The other (Pictured) shows a Microsoft Word document with different fonts. Simulates a 15" computer monitor with shiny screen. has intentional errors to show red/green highlights.
