Eye structure
Eye structure
Iris: colorful part
Cornea: A clear dome on the iris
Pupil: Opening of black circular in iris, which gives light
Sclera: The white part of your eyes
Conjunctiva: A thin layer of tissue which leaves the cornea and covers the entire front part of your eyes.
Macula: A small, sensitive area of the retina needed for central vision. It includes shovel.
Lens: A clear part of the eye behind the iris that helps in focusing the light on the retina. This allows the eye to focus on both distant and close objects.
Vitreous humor: A clear prison is filled inside the eye.
Fovea: The center of the macula, where your vision is the fastest.
Optic nerve: More than 1 million nerve fibers are bundles that take visual messages from the retina to the brain.
Retina: The light-sensitive tissue behind the eyeball. It sends the brain to electrical impulses through the optic nerve.
The lens is behind the iris and the pupil, which helps in focusing behind your eyes. Most of the eyes are filled with clear gel which is called vitreous. The inner layer of light eye through the pupil and lens behind the eye is covered by special light-sensing cells, which is collectively called the retina. It changes the light in electrical impulses. Behind the eye, your optic nerves carry these impulses to the brain. The Macula is a small extra sensitive area in the retina that gives you central sight.
Hyphema: In front of the eyes, bleeding between the cornea and iris. Hyphema is usually caused by injury.
Charitis: Swelling or infection of the cornea. This usually occurs when the germs come to scratch on your cornea.
Myopia (near sight defect): You can not clearly see at a distance. Your eye “is too long” for the lens, so the light will not focus properly on your retina.
Optic neuritis: Optic nerve gets swollen, usually due to an immune system. Result: Pain and vision loss, usually in an eye.
Pterygium: Usually a condensate mass on the inner part of your eyeball, it can cover a part of the cornea and can cause vision problems.
Retinal detachment: The retina tends to recoil from behind your eyes. Trauma and diabetes is the most common cause of this problem, which often requires urgent surgery.
Retinitis: Retinal inflammation or infection. It can be a long-term genetic condition (retinitis pagmentosa) or may come from infection.
Scodoma: A blind or dark place in your viewing area.
