The main structures of the bird eye are similar to those of other vertebrates.The retina is a relatively smooth curved multi-layered structure containing the photosensitive rod and cone cells with the associated neurons and blood vessels.
The geometric configuration in the double-layered structure is very required to be started from the conceptual design with low cost, high performance and quality. In this point, a structural-topological shape concerned with conceptual design of structure is important.

Moving forward, it's essential to keep these visual contexts in mind when discussing Bird Rooms With Double-Layered Structures.
