view
矙 centers on the act of looking or viewing, often with a sense of peering or observing from a vantage point.
矙 combines 目 (eye) with 闞, which likely provides the sound and contributes a meaning related to looking or peering. The exact historical development is uncertain.
The eye 目 on the left and the complex right side 闞, which contains a gate 門 and ear 耳, suggest peering through a gate to view something, perhaps listening as well.
For カン, imagine viewing a can through a gate: can -> カン, and your eye 目 peers at it.
