Welcome to a fun journey about how our eyes help us see the world! Let’s explore how the sense of sight works.
Our eyes have many parts, each with a special job. Some parts keep our eyes safe, while others help us see.
Our eyebrows, eyelids, eyelashes, and lacrimal glands work together to protect our eyes. Eyelids blink many times a minute to keep our eyes clean and moist. Lacrimal glands help wash away germs and dust.
The parts that help us see include the iris, pupil, eye lens, and retina.
Light first reaches the iris, which decides how much light should enter the eye. Then, the light travels through the pupil to the inside of the eye. The eye lens focuses on what we are looking at, like a camera lens.
The retina, located at the back of the eye, catches the light and sends messages through the optic nerve to the brain. The brain then understands what we are seeing.
To keep our eyes healthy, it’s important to wear sunglasses when it’s sunny, especially at the beach or in the mountains. Sunglasses protect our eyes from bright sunlight.
And that’s how our amazing sense of sight works!
Did you enjoy learning about eyes? There are many more exciting things to discover! Keep exploring and learning new things every day!
Eye Parts Exploration: Create a simple model of the eye using everyday materials like paper, cardboard, and markers. Label the parts such as the iris, pupil, lens, and retina. Discuss with your friends or family about what each part does. Can you think of any other objects that have similar parts or functions?
Light and Shadow Experiment: Use a flashlight and different objects to explore how light helps us see. Shine the flashlight on an object and observe the shadows it creates. Try changing the distance and angle of the light. What happens to the shadow? Discuss how light helps our eyes see objects and how shadows are formed.
Observation Walk: Go on a short walk around your home or school and observe the different things you can see. Make a list of objects that are easy to see and those that are harder to see. Think about how light and the parts of your eye help you see these objects. Share your observations with a friend or family member.

Smile and learn! Today we are going to learn how the sense of sight works.
[Music]
The human eye has different parts; some parts protect the eye while other parts are responsible for vision. The parts that protect the eye include the eyebrows, eyelids, eyelashes, and lacrimal glands. The eyelids open and close many times per minute, helping to keep the eye clean and moist. The lacrimal glands assist in cleaning the eye and eliminating germs and dust that reach it.
The parts of the eye responsible for vision are the iris, pupil, eye lens, and retina.

Visual information reaches the iris, which controls the amount of light entering the eye.

Then, light passes through the pupil and reaches the inner part of the eye. The eye lens receives this information and focuses on objects and shapes.
[Music]
The retina is located at the back of the eyeball; it receives light and transmits this information through the optic nerve. The optic nerve carries the information to the brain, which recognizes and comprehends what our eyes are able to see.
To protect your eyes, you should wear sunglasses during the summer, especially if you’re at the beach or in the mountains.
And this is how the sense of sight works!
