Morphology
The meaning 'a device related to vision or light' is directly and transparently derived from combining 'optical' (related to light/vision) with 'device' (a manufactured item for a purpose). This adjective + noun composition is a straightforward, cross-linguistically common pattern that a B1 learner who knows both constituents will immediately understand.
Etymology
Optical device is a name for a device that deals with optical things — think of a lens bending 'light' so you can 'see' tiny or far objects. That's why it means any tool that makes, changes, or guides 'light' to help us see or make pictures.
