Why Eye Health is Important to Stay Healthy
Eye health is the maintenance and conservation of eye health for long life. The eye is one and only organ essential for vision – is a covered organ with specialized body tissues. It consists of two different types of cells – the lens and the gland (which looks for and collects fats).
The retina and the optic nerve forms the “radiology system” in the retina. The eye has an organoid called the cornea – a thin film of cells at the very edge of the eye and surrounded by liquid which filters light out of the eye. The cornea is covered by layers of tissues called iris – a thin layer of cells surrounding the eyeball that produces light.
The lens – a material embedded between the tissue layers to let light see through the substance. The cornea is situated at the center of the eye and the eye is located at the tail of the cornea. Outside, the eye is called the optic nerve. The cornea of the cornea contains a stroma, the non-aniline substance which picks up light and creates a rainbow of colors. The cornea is shaped like a whisk, and the lens is located in the tip. Since the cornea is smooth, the eye is known as a “queen”.
The eye is vascularized; the eye receives blood supply with the blood vessels on the periphery of the eye. There are blood vessels coming from the heart and veins in the upper and lower eyelids. The average blood volume in the eye is 4 liters.
The eye lids are delicate vessels at the outside and the eye’s drain tubes and drainage tubes help to drain the blood that the eye receives. “The eye contains cells that feed on blood, but these cells are special; they receive blood supply from the circulatory system.” (Depression in Ankylosing Spondylitis)
The eye does not receive, nor move blood. This blood still circulates in the eye while it circulates in the circulatory system. This circulatory system does not include heart or brain, but rather consists of capillaries within the eye and besides the circulatory system.
The retina is the “light-sensing tissue” that is covered with the tissue layer that covers the cornea. The eyeball’s optic nerve divides into four parts; the spindle structures and the three external structures that are the macula, the iris, and the iris are made up of the body tissues and tend to be more sensitive.
The optic nerve receives light from the eye, which is reflected through the eye cells into the eye’s sensory glands. The sensory glands have receptors that are located in the retina, and hence, the brain then receives the light signal.
The ocular cortex is the shared tissue that has been above the skin and the blood vessels as well as the tissues. It has three extremely distinct ocular surfaces; they have skin on the upper, middle, and the lower parts of the ocular surface.
The ocular cortex has the distinction of having the most “elastic synovial fluid” of any of the body’s organs. The ocular cortex and oculites have more of a blood vessels than in the liver, kidneys, and the gall bladder. In fact, the ocular cortex is four times as capillary shaped as the vascular tissues of the heart and renal cortex of the brain. The ocular cortex has a thicker coat of skin than the melanocytes cells of the skin.
The optic nerve lies over the area of a sheet of cartilage. The optical nerve consists of two two different types of ocular tissue – the pigment of the eye and the coating of the cornea. These ocular tissues have photoreceptor cells; they collect light signals coming from the eye and using an ocular lens and a fibrous field, they convert the light signals into a picture. The ocular cortex sits at the top of the eye that is separated from the eye’s surface by the swelling gland (near the eye’s forehead).
The first side of the ocular cortex is more active in the processing of tactile and auditory signals than the second side. A movement of the eyeball acts a heat sensor that changes the ocular cortex’s activity. Also, on the eye’s surface is a glowing structure called the blood vessels. This organ is similar to the major veins of a human body. The ocular cortex, the oculums, and the cornea are kept from UV radiation by the cornea.
