The eye has multiple layers, the outermost layer that covers the white portion of the eye is known as the conjucntiva, beneath it is the sclera (which gives the eye its white color). The clear covering over the pupil is the cornea which in contiguous with the conjunctiva except without any blood vessels penetrating it. Beneath the cornea lies the iris (which is contigious with the sclera), which is contained within the anterior chamber of the eye which is filled with aqueous humor, a liqiud medium that provides nutrients to the structures it bathes. The lens, which is deformable and helps to focus light on the retina lies posterior to the iris and pupil (which is the open space in the center of the iris). Posterior to the lens and the sclera lies the vitreous humor which is a jelly like substance that fills the inside of the and lies directly of the retina, which is the back of the eye. The retina also has multiple layers.
The thin clear layer that forms the outer coat of the eyeball is called the cornea.

The sclerotic coat is the name for the outermost layer of the eyeball. It functions primarily as protection for the eyeball.

Vascular Coat or Uvea is the middle part of the wall of the eye. Uvea has a rich supply of blood vessels that provides nutrients of the eye.
Did you mean the Lamina Fusca Sclera? The problem is the phrasing is awkward with this question so I have no idea what it is you're looking for. That's my best guess from what I can tell.
The opaque middle layer of the eyeball is referred to as the choroid. The structure is made up of a total of four layers.
