to gaze, to ogle, to look at
眽 centers on looking intently at something, often with a sense of staring or ogling. The given meanings all involve a focused, sometimes intense, visual attention.
眽 combines 目 (eye) with a phonetic component that is visually similar to 永. The character likely originated as a phono-semantic compound where the right side contributed the sound and the eye radical indicated looking.
The eye 目 on the left is fixed on something, while the right side looks like a person leaning forward with intense focus. Together, 眽 means to gaze or stare intently.
For バク, imagine a person staring so hard they back into a wall: back -> バク, and their eyes are locked in a gaze.
