How to determine the eyelid?Here we will provide a video as a reference.

Note:

With the contraction of the pupil, the eyelids have the following types of movement: slow and fast. The basis for determining whether the eyelids move fast or slow is the number of times the pupils contract. When the number of times the eyelids are more than or equal to the number of pupil contractions is called fast, the number of times the eyelids are less than the number of pupil contractions is called slow.
