What highly vascular layer of the eye absorbs light rays and nourishes the retina?

Retina
Iris
Choroid
Sclera

The correct answer is: Choroid

The highly vascular layer of the eye that absorbs light rays and nourishes the retina is the choroid. This layer is situated between the retina and the sclera and contains a rich network of blood vessels that supply nutrients and oxygen to the outer layers of the retina. The choroid also plays a crucial role in absorbing excess light, preventing reflections that could distort vision. By absorbing light rays, it enhances visual acuity and helps maintain the overall health of retinal cells. The structure's vascular nature is essential for supporting the metabolic demands of the retina, which is vital for proper visual function.
