big-eyed
睅 centers on having large, prominent eyes. The single meaning 'big-eyed' is straightforward and describes a physical trait.
睅 combines 目 (eye) with 旱, which likely contributes the sound. The character is rare and its exact historical development is uncertain.
The left side is an eye 目, and the right side 旱 looks like a wide, staring eye with a flat top. Picture a face with one huge eye on the left and another huge eye on the right: 睅 means big-eyed.
For カン, imagine a big-eyed can of soda staring at you: can -> カン, and its oversized eyes bulge from the can.
