EYES
Your eyes are sensory organs that provide your brain with information about the world around you. They do the physical part of seeing capturing light and sending signals to your brain which processes these signals into the images you perceive. Eye health is very important because symptoms in your eyes can indicate broader health issues. Experts recommend prioritizing eye care.
What Are Eyes?
Eyes are sensory organs which allow vision by capturing visible light and converting it to signals that your brain may understand. Since the brain lacks any direct sensory abilities it must rely on the senses such as eyes and the other senses for instance hearing and touch to understand the environment.
Most of the human beings are born with two eyes that can give a wide angle view about 200 degrees horizontally and 135 degrees vertically depth perception, 3D vision, and the ability to perceive in color.
It is significant to distinguish between sight and vision. The work that your eyes do is called sight, while the whole process that involves capturing light and then passing it to your brain for interpretation and understanding is called vision.

How Do Eyes Work?
The process of seeing starts with light entering the eye. Different parts of the eye including the cornea aqueous humor lens, and vitreous humor bend and focus the light so that it exactly falls on the retina.
If the focus is off objects may appear blurry. Tiny muscles in the eye adjust its shape to fine-tune the focus. When light reaches the rsigna its cells convert the information into coded signals which describe details like color and intensity. These signals travel to the brain where they are decoded and used to create the image you see.
Anatomy of the Eye
The human eye is an intricate organ made up of various parts that work together to enable vision. Some of the key components include:
Cornea: This is a clear layer that protects the eye and helps bend incoming light. It is kept moist by tear fluid.
Sclera: This is commonly referred to as the white of the eye. It provides structure and protection.
Each part is critical for sharp focus light processing and protection and overall the eye is one of the most incredible organs for the perception of the world.
