false.
the choroid is the opaque middle layer of the eye that contains blood vessels and provides the blood supply for the entire eye.
Retina
The pupil and the lens. If you have large pupil like 7mm, you would feel glare at night when driving after lasik surgery. When you have cataract in old the scattering of light would make you photophobia Details from vodvos.com
The choroid coat is a vascular layer located behind the retina in the eye. It provides nutrients and oxygen to the outer layers of the retina and helps regulate the amount of light entering the eye by absorbing excess light.
Choroid cysts primarily occur in the eye, specifically in the choroid layer of the eye, which is located between the retina and the sclera. However, similar cystic structures can also appear in other parts of the body, such as the brain (e.g., choroid plexus cysts). While the term "choroid cyst" is most commonly associated with the eye, it's important to recognize that cysts can form in various tissues and organs.
The correct order of the layers of the eyeball from the outside to the inside is the sclera (white part), choroid, retina (consisting of the outer pigmented layer and the inner neural layer).
The pigmented layer of the eye is called the uvea.
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 choroid is the layer responsible for providing the pigmentation that forms most of the pigmented vascular tunic of the eye. It helps to absorb excess light and prevent reflection within the eye, contributing to visual acuity.
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.
choroid :)
t makes sure that the eye stays in place. That is a horrible answer with no truth to it at all. The choroid is a layer of the eye deep to the retina and superficial to the sclera. It provides oxygen and nutrients to the retina through its extensive network of capillaries. The retina itself does not have a huge vascular supply, because the vessels would interfere with the formation of the image in the eye. This is why the choroid is necessary. The choroid is also very heavily pigmented due to an abundance of melanin. This increased pigment allows the choroid to absorb excess light and minimize reflections within the eye. The choroid along with the iris and ciliary body make up what is known as the uveal tract.

No. The outer layer of the eyem the white part, is the sclera. The choroid is the next layer and the retinal is next.
This is the middle layer of the eyeball and it is composed of the choroid, ciliary body and iris.
