How do you feel the vibration of your eyes? We must refer to the video screen and judge with experience.

Note:

The eye is shrunk by the pupil, and the intensity of the eye vibration has two forms: strong or weak. We can sense by holding the head of the pigeon: when the vibration is strong, the hand can have a strong sense of vibration and also has a slight touch; when the vibration is weak, the hand does not have strong vibration and touch.
