The eye has many parts which work together to accomplish vision and to keep the structures required for vision safe from infection and injury.

Function of all parts of eye. If a portion of the eye becomes damaged you may not be able to see effectively or lose your vision all together. JGI Getty Images. The iris is the area of the eye that contains the pigment which gives the eye its color.

It absorbs light rays from our surroundings and converts them in such a way that the facts in the brain can be treated further. The iris is the Pigmented area of eye that decides the color of eyes. Adjusts the size of the pupil and controls the amount of light that can enter the eye.

Light enters the eye by passing through the transparent cornea and aqueous humor. It includes the medial rectus lateral rectus superior rectus inferior rectus inferior oblique and superior oblique. Anatomy Structure and Functions The eye is a sensory organ.

The iris controls the size of the pupil which is the opening that allows light to enter the lens. The sclera is perhaps the most important part of the eye as without it we wouldnt be able to see. An eye also consists of six muscles.

The sclera contains this pressure and simultaneously keeps the iris the pupil the retina and the other parts of the eye in position so that the correct focal length is always maintained. The eye is an organ that detects light and sends signals along the optic nerve to the brain. The pupil or black dot at the center of the eye is a hole through which light can enter the eye.

The pupil the center portion of the iris is the part of the eye which controls how much light goes into the eye. It converts light into electrical impulses. This allows the eye to take in more or less light depending on how bright it is around you.

Layers of the eye. The pupil is the opening at the center of the iris. It is the pigmented coloured portion of the eye visible externally.

The eye and brain form a component that has developed together in the course of evolution visual system. The sclera or white part of the eye protects the eyeball. Eye Parts and Functions.

The eyeball is surrounded by a three-layered wall the three coats of. The main function is to refract the light along with the lens. The inside lining of the eye is covered by special light-sensing cells that are collectively called the retina.

The following chapters will explain anatomy and function of the three coats as well as of the inner part of the eyeball. The main function of the iris is to control the diameter of the pupil according to the light source. The surface of the eye and of the inner eyelids is covered by a clear protective membrane called the conjunctiva.

The different parts of the eye allow the body to take in light and perceive objects around us in the proper color detail and depth. The inner part of the eyeball. It contains the lens and the vitreous body and is divided into the anterior and the posterior chamber.

Structure and function of eye 1. It carries impulses for sight from the retina to the brain. Behind the eye your optic nerve carries.

This black area is actually a hole that takes in light so the eye can focus on the objects in front of it. In humans the eye is a valuable sense organ that gives us the ability to see. The retina is the light-sensitive tissue at the back of the.

The retina converts light into electrical impulses that are. The main parts of the human eye are the cornea iris pupil aqueous humor lens vitreous humor retina and optic nerve. The pupil looks like a black dot in the middle of the eye.

The iris or colored part of the eye surrounds the pupil. The iris is a ring of muscles in the central part of the eye that is helpful in regulating the amount of light entering the eye by controlling the size of the pupil. The basic function of these muscles is to provide different tensions and torques that further control the movement of the eye.

This part is also important for light refraction and focusing of images onto the retina. These parts have important independent functions. The eye has many parts that must work together to produce clear vision.

The eye is one of the most intricate parts of the body. It is the small aperture located in the centre of the Iris. It allows for light perception and vision including the ability to differentiate between colors and depth.

It takes in light so the eye and focus on the objects in front of it. The different parts of the eye permit the body to take in light and perceive objects around us in the proper color information and depth. Rods function in dim light and are responsible for black and white vision while cones support daytime and color vision.

This allows people to make more educated decisions about their environment. Distinguishes light and darkshape colour brightness distance ofobjects. Gift of the Creator Gives us the sense of sight 70 of all sensory receptors are in the eye Spheroid structure about 23 the size of aping-pong ball Functions.

The pupil appears black because all of the light which enters it is absorbed by the tissues behind the eye. This area surrounds the pupil and uses the dilator pupillae muscles to widen or close the pupil.
