Answer:

The right order is 3, 1, 2.

Explanation:

The most superficial layer is 3, which describes the Cornea. This layer, which is first hit by light, is made of transparent and resistant fabric. It protects the eyeball from trauma and contamination and helps shape the globe and refract light.

Then, the layer described as 1 is the pigmented part that has melanocytes, which may be the uvea that consists of the whole of the iris, choroid membrane and ciliary processes.

Finally, the deepest layer in this question describes the lens, which is a gelatinous biconvex lens. This important structure enables the eye to focus on objects.
