🌟 Introduction
The human eye is one of the most vital sensory organs, providing our brain with visual information to perceive the world around us. It plays a crucial role not just in vision but also in detecting early signs of health issues throughout the body.
🔍 What Are Eyes and How Do They Work?
Our eyes collect light from the world around us. This light passes through different parts of the eye, gets focused, and reaches the retina at the back of the eye. The retina changes light into electrical signals, which the optic nerve sends to the brain. The brain then creates the images we “see.”
🧬 Main Parts of the Human Eye
- 🔹 Cornea – Begins focusing light.
- 🔹 Iris – Controls how much light enters.
- 🔹 Pupil – Lets in light.
- 🔹 Lens – Focuses light onto retina.
- 🔹 Retina – Detects light and color.
- 🔹 Macula – Central detail and color vision.
- 🔹 Optic Nerve – Sends signals to brain.
- 🔹 Vitreous Humor – Keeps eye’s shape.
- 🔹 Sclera – The white outer layer.

- 📌 Refractive Errors – Nearsightedness / Farsightedness
- 📌 Cataracts – Clouded lens
