Apr 29, 2023 · Light is focused into the eye through the clear, dome-shaped front portion of the eye called the cornea. Behind the cornea is a fluid-filled space called the anterior chamber. The fluid is called aqueous humor. The eye is always producing aqueous humor.

The conjunctivais the membrane covering the sclera (white portion of your eye). The conjunctiva also covers the interior of your eyelids. The conjunctiva helps lubricate the eyes by generating mucus and tears. It also aids in immunological monitoring and prevents microorganisms from entering the eye. Pink eye (conjunctivitis) occurs when this thin ...
The whites of the eye (sclera) cover more than 80% of the eyeball’s surface. The sclera has a smooth, white exterior but is brown on the inside. It has groves that help properly attach the eye tendons, providing stability and protection while staying flexible. This allows the eye to move as needed to see different objects. The episclera is a thin l...
The iris is the colored part of the eye and is unique to each person. This structure is located in the front of the eye, between the cornea on the outside and the lens on the inside. The iris primarily regulates how much light reaches the retina by controlling the size of the eye’s “window,” or pupil. As a result, it narrows in bright light while o...
The pupil is seen as a black dot in the center of the iris. It’s essentially a hole that allows the eye to focus on the things in front of it. Similar to the iris, they open and close to regulate the amount of light that enters the eye. When light enters the eye through the lens, it focuses light rays through the pupils and into the retina. The dif...
The cornea is the clear and protective outer layer of your eye. Along with the sclera, the cornea is a barrier against dirt, infectious microorganisms, and other substances that can damage the eye. Aside from protection, the cornea also plays a significant role in vision. Its dome-shaped surface bends light as it passes through the eyes, allowing i...
The uvea is the eye’s middle layer. It is located underneath the white part of the eye (the sclera). It’s composed of three parts, namely, the iris, the ciliary body, and the choroid. These structures control some eye functions, such as adapting to varying levels of light or object distances. If any structures become inflamed, the resulting conditi...
This vascular layer is located between the sclera and retina of your eye. It delivers nourishment from the blood and oxygen supply to the retina’s outer layers. Essentially, the choroid is the source of life that keeps the retina functioning effectively. It also reflects light, causing the red-eye effect in photographs.
The retina is a light-sensitive layer that covers your eye’s rear surface. Images are transmitted to the retina when your eye picks up the images. It converts images into impulses that are sent to your brain through the optic nerve, allowing you to see and interpret images. Some of the ocular conditions that affect the retina include: 1. Diabetic r...
The eye has six muscles that come from the eye socket (orbit) and work to move the eye up and down, side to side, or in a circular motion. These muscles include: 1. The superior rectus.Attaches to the top of the eye and moves the eye upwards. 2. The inferior rectus.Attaches to the bottom of the eye and allows downward eye movement. 3. The medial re...
Light rays are focused on the macula lutea when an eye looks directly at an object. The macula lutea is a yellow oval area in the retina’s center (back of the eye). The center of the macula is known as the fovea. The macula lutea is the section of the retina responsible for sharp, detailed central vision (visual acuity). It has a high concentration...
May 30, 2018 · The coloured part of your eye is called the iris. The iris is made up of muscle fibres which help to control the size of the pupil. The pupil is not an actual structure but the circular opening in the middle of the iris.
Nov 15, 2023 · The parts of your eye include the: Cornea. This protects the inside of your eye like a windshield. Your tear fluid lubricates your corneas. The corneas also do part of the work bending light as it enters your eyes. Sclera.
Mar 16, 2024 · The gland has two parts: one closer to the eye and one deeper inside the eye socket. The part closer to the eye is called the palpebral lobe; you can see it if you turn your upper eyelid inside out. The deeper part is the orbital lobe, which connects to the palpebral lobe with small tubes.
The optic nerve carries signals of light, dark, and colors to a part of the brain called the visual cortex, which assembles the signals into images and produces vision. Posterior chamber. The back part of the eye's interior.
Mar 11, 2023 · The front surface of the eye is called the cornea, a transparent layer that offers protection and allows for light to enter the eye. Surrounding the cornea is the white parts of the eye called the sclera, which wraps around and provides the round structure of the eyeball.
