This could be a reCAPTCHA test, to train the models to better detect eye position and face angle.

It's already using https://ai.google.dev/edge/mediapipe/solutions/vision/face_d... for detecting the eye (and nose) position for the perfect fit ;) The face detection should be done locally, so hopefully Google is not fine-tuning their models based on this.
