there are 3 layers to the animal and human eye:
1. External, which includes cornea and sclera
2. Intermediate, which has two parts
a. Anterior, includes iris and ciliary body
b. Posterior, includes choroid
3. Internal, which is the retina.
Some nocturnal animals like cats for instance have a layer in the back of the eye that reflects/multiplies light coming into the eye, thus allowing them to see in the dark better. This layer is called the "Tapetum lucidum".
This is a very vague question as every section of they eye has many layers. For example, the cornea (clear layer on the front of the eye) has 5 layers. The retina (in the back of the eye) has 10 layers. But these are only 2 areas of the entire eye.
alligators have 2 layers of skin on they're eye's
choroid
The 5 layers are:EpitheliumBowman's MembraneThe StromaDecemet's MembraneEndothelium
The human eye is made up of three layers. These are the outer layer, the middle layer and the inner layer.
The three layers that are cut through when doing a dissection of a cows eye are the external layer, internal layer, and the intermediate layer. The white part of the cows eye is called the sclera.
There are harmful effects of damage of ozone layer are many. Some of them are skin cancer, eye cataract etc.
there are many layers
it has 7 layers!!
The lens, because it forms in multiple layers.
how many layers does the earth have and name them
Why are there so many layers in the atmosphere
Choroids are the vascular layer of the eye. It lays between the retina and the sclera of the eye. The choroid provides oxygen to the outer layers of the retina.
