The eyes are perhaps the most striking feature in a person’s face, but how much do we know about it? Are you, at all, familiar with the windows to your soul? If not, then let’s get you started on getting to know your eyes.
- Eyelids – each of your eyes has an upper and lower eyelid that protects them from bright lights and foreign objects that could potentially cause damage to your eyes. Every time your eyelids blink, they are lubricating the surface of your eyes to help keep them moist and germ-free.
- Sclera – is the white portion of the eye. It is responsible for the spherical shape of your eyeball and protects the eye’s internal structures.
- Conjunctiva – is the transparent membrane that covers the sclera. If you look at your eyes closely and see the tiny blood vessels on the white portion, they are located inside the conjunctiva
- Pupil – the dark circle in the middle of your eyes that allows light to pass through and enable you to see
- Iris – is the colored portion of the eye that consists of muscle fibers that control the size of the pupil, making it bigger or smaller depending on the amount of light entering the eye
- Cornea – is located at the front of each eye and acts as a protective dome consisting of clear tissues that focus the light entering the eye
- Lens – is a small elliptical structure inside the eye that catches the light rays and focuses them to sharpen your vision
- Vitreous cavity – this is the space that extends from behind the lens throughout the back of the eyeball. It is filled with a jelly-like substance that maintains the shape of the eyeball.
- Retina – the layer of thin tissue that lines the inner wall at the back of the eyeball consisting of cells that capture images being seen by the eye
- Macula – is the central portion of the retina that is packed with light-sensitive cells that allow you to see even the smallest details
- Optic nerve – carries information from the retina to the brain
