choroid - a highly vascular membrane in the eye between the retina and the sclera; a dark pigmentation minimizes the scattering of light inside the eye.
(http://www.thefreedictionary.com/choroid)
The pigmented tunic you are referring to is the choroid, which contains melanin that absorbs excess light and prevents it from scattering within the eye. This helps to improve visual acuity and reduce glare.
The layer in the eye that contains dark pigment to absorb extra light and keep the inside of the eye dark is the choroid layer. The melanin pigment in this layer helps prevent light from scattering inside the eye, allowing for better vision and reducing glare.
The choroid plexuses form the bulk of the heavily pigmented vascular layer in the eye. This layer is richly supplied with blood vessels and helps nourish the retina. The pigment in the choroid absorbs excess light, preventing it from scattering within the eye and improving visual acuity.

The vascular layer of the eye is also known as the uvea. It provides nourishment to the eye and consists of the iris, ciliary body, and choroid. This layer contains blood vessels that supply oxygen and nutrients to the structures 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 Iris
Scattering of light is called dispersion .
Light scattering refers to the process by which particles or obstacles in a medium cause light rays to deviate from their original path, leading to a change in the direction of the light. This phenomenon is responsible for effects such as the blue color of the sky, the white appearance of clouds, and the visibility of laser beams in the air.
One can find information on light scattering on the Wikipedia website. There is a comprehensive description of light scattering on that page including descriptions of the different types of light scattering.
the scattering of light by colloids is known as tyndall effect. it is named after the scientist who discovered it.
