a. The device layer is a protective cover layer called sclera, consists of two elements [3, 4]:
 Sclera covers about five-sixths of the surface of the eye.
 The cornea, the peripheral layer consists of a sort of bulge-shaped transparent window.
b. The middle layer is called uvea, is also divided into two elements[4,5]:
 Choroid, a thin vascular layer between the sclera and the retina, rich in vessels and nourishing.
 The iris is a small disc pigmented containing muscle tissue in its thickness, pierced at its center with a variable diameter orifice, the pupil, and arranged vertically …show more content…

Macular edema is a common denominator for many retinal diseases that lead to a more or less severe visual loss, it is the accumulation of fluid in the macula causing its thickening. It occurs when the blood vessels in the retina are bleeding [15].
Macular edema is not a disease, but is the result of one, can be caused by many factors including:
 Metabolic conditions (diabetes)
 Blood vessel diseases (vein occlusion)
1.1.2.3 Retinal detachment
Retinal detachment is caused by the presence of a small fluid pocket under the retina. It follows, in most of cases, a tear in the retina that allows the intraocular fluid to infiltrate and lifting. The separated zone no longer works.
The retinal detachment is a serious condition that usually affects middle-aged or older. If not treated quickly, it causes problems and vision loss [17]

    In the eye, the cornea is entry point for light. In simple terms, the cornea is the transparent tissue at the front of the eye that functions as the window through which all light has to pass through on its way to forming visual perception. The reception of a clear image is dependent on the integrity of the corneal surface. However, with age, the lens is subject to cataracts and presbyopia in addition to other damage. This damage to the surface of the eye effects how people see and could potentially slow their reaction time to what they are seeing.

The retina contains “photoreceptor

    Individuals are grateful for their eyes, but rarely does anyone think, “what holds my eyes in place, and how is my eye protected?” This is what the orbit is responsible for, which contains the bones surrounding the eyes (“Blowout Fracture,” n.d.). Orbital fractures happen a lot, but one of the most common is a blowout fracture, which results from direct trauma to the orbit such as a small sports ball or a fist (Gaillard, n.d.). Luckily, our eyes usually do not undergo significant damage due to the orbit protecting them, but unfortunately the bones at the bottom of the orbit known as the orbital floor are thin and typically break easy causing a blowout (Zeigler, n.d.). Also, there are four different types of blowout fractures all occurring

In severe cases, these feelings can even manifest themselves deeply inside of a person and lead to eating disorders, depression, anxiety, self-hatred, and even suicide. In The Bluest Eye, Toni Morrison uses the insecurities of the female characters to demonstrate that beauty standards are a danger to society, as they perpetuate racism and self-hatred.

The light then travels to a lense that acts like a camera, and focuses on the objects that we need to see. Without the advanced set of eyes that we have, we would see things as fuzzy round circles instead. We see in chapter ten a big part of evolution and how we are related to other animals.
