💡Quick Tips & Safety
  • Dim room. Avoid Night Shift/True Tone if possible. If you feel unwell, press Esc.
  • The demo uses fixed parameters (15 Hz, small dot size). Only the stimulus contrast adapts automatically.
  • Threshold here is a rough estimate from reversal means. A research version would use Bayesian adaptive staircases and calibrated display contrast.
