Anatomy Of Eye – FAQ
The primary function of the eye is to capture light and convert it into electrical signals that the brain can interpret as visual images. This process involves various parts of the eye working together to focus light onto the retina, where photoreceptors detect it and send signals through the optic nerve.
The cornea is the eye’s outermost layer, playing a crucial role in focusing incoming light. It acts as a protective barrier against dust, germs, and other harmful matter. The cornea’s curvature helps bend light rays, directing them towards the lens, which further refines focus onto the retina, ensuring clear vision.
The retina is a thin layer of tissue located at the back of the eye. It contains millions of photoreceptors, known as rods and cones, which detect light and color. These photoreceptors convert light into electrical signals, which are transmitted to the brain via the optic nerve. The brain then interprets these signals as visual images.
The lens is a transparent, flexible structure situated behind the iris. It works in conjunction with the cornea to focus light onto the retina. The lens adjusts its shape to change the focal distance, allowing us to see objects clearly at various distances. This process, known as accommodation, is vital for sharp vision.
The optic nerve is a crucial component of the visual system, connecting the eye to the brain. It transmits electrical signals generated by the retina to the brain’s visual cortex. The brain then processes these signals to create the images we see. Damage to the optic nerve can lead to vision loss or blindness.
