How to Take the Test

• Purpose: This test checks your central vision by mapping areas where you can’t see a flickering noise pattern.
• Preparation: Cover the eye not being tested (e.g., with your hand or an eye patch). Sit comfortably in a well-lit room.
• Distance: Hold the screen at the distance shown below to test your central 24 degrees of vision.
• Steps:
  1. Enter your name and select the eye to test.
  2. Only look at the red square during the test with one eye.
  3. Look for areas in the surrounding screen that DO NOT flicker. These areas may be black, dim or cloudy. These are the abnormal areas.
  4. Move the yellow cursor with your mouse. Click and drag to draw red shapes over any areas where you can’t see the noise.
  5. If you make a mistake, click "Undo" to clear your drawing and try again.
  6. Click "Next Quadrant" to test all four sections, then "Finish Test" to see your results.
• Tip: Draw carefully to mark only the areas you can’t see. The test takes about 1-2 minutes per eye.
