Which is the innermost and outermost layer of eyeball?

The inner layer of the eye is formed by the retina; its light detecting component. The retina is composed of two layers: Pigmented (outer) layer – formed by a single layer of cells. It is attached to the choroid and supports the choroid in absorbing light (preventing scattering of light within the eyeball).
