Test Instructions

📋 About the Test

The LANG-STEREOTEST® I is a screening test for stereoscopic vision (depth perception) using random dot stereograms. It evaluates binocular vision without requiring special glasses.

👁️ Test Procedure

  • Position yourself approximately 40 cm (16 inches) from the screen
  • Keep both eyes open throughout the test
  • You will see one test image with random dot patterns
  • Try to identify all objects (Cat, Star, Car) that appear in the pattern
  • Select all shapes you can see before submitting

⚡ Test Objects

  • Cat - 1200" disparity (left side, easiest to see)
  • Star - 600" disparity (center, medium difficulty)
  • Car - 400" disparity (right side, most challenging)

⚠️ Important: This is a simulation for educational purposes only. It cannot replace actual clinical testing with the physical LANG-STEREOTEST® card. For accurate diagnosis, please consult an eye care professional.
