According to one embodiment, an eye-worn electronic device includes a first nose pad, a first electrode, a second nose pad, a second electrode and a third electrode. The first electrode is on the first nose pad. The second electrode is on the second nose pad. The first electrode and the second electrode are in a first straight line extending in a first direction and are used for measuring first ocular potentials in the first direction. The third electrode is on the second nose pad and is at a position distance away from the first straight line. The first electrode and the third electrode are in a second straight line extending in a second direction different from the first direction and are used for measuring second ocular potentials in the second direction.
