The eyes toggle linearly, sharply and with a trajectory. They will toggle between 2 (or a max of 3) focal points in a short time span; alternating between those two points in either slow or fast speeds.
This signal demonstrates a psyche that is quite uncertain/doubtful or in the midst of reconsideration or reevaluation of its understanding. It reveals a psyche that is engaged in real-time mental visualization or linguistic restructuring of thoughts. The mind is creating new ideas and information by exploring novel ways of piecing together existing data, and synthesizing a new perspective out of it.
Unlike Ne eyes, which are scatter-shot and which gently toggle about in a variety of different vectors (going up/down/left/right all in two seconds) Se eyes tend to return again to the same areas they've toggled before. They toggle less sporadically, and instead toggle between various focal points in the environment. For example, they may go from the cup on the table, to the lamp and back. Or perhaps between the cup, the lamp and the person they're talking to. This will differ from Ne's brushstroke toggling which has no focal points and instead darts about aimlessly, never fixating on anything in the direction of their eyes. Below we see this difference:
Blue: Ne Brushstroke Movements / Red: Se Pointed Toggling
The above two GIFs show blue or red dots representing each individual shift in focus that appears in the eyes of Ne and Se respectively. The core differences between the two eyes can be summarized as:
Both above attributes must be present in the toggles for them to be identified as belonging to either Ne or Se.
