parts and functions of the eyes Part, description, function cornea, front part of the tough outer coat, the sclera it is convex and transparent refracts light - bends it as it enters the eye iris, pigmented - decides the colour of your eyes - so light cannot pass through its muscles contract and relax to alter the size of its central hole or pupil controls how much.

Diagram - parts of the eye cornea (cor-nee-a) this is the layer that covers the front of your eye it is clear like glass and it has no blood vessels in it it focuses the light that is coming in through it, and with the lens it makes sure that the image that reaches the back of the eye is in focus sclera (sk-ler-a. Human eye diagram when you talk of the human eye structure, they exist in pairs, each one being approximately 25 cm in diameter there are following main parts of human eye: sclera: the knowledge of eye parts and functions is both useful and interesting the white part of our eyes is known as sclera it consists of. At the junction of optic nerve and retina, there are no sensory nerve cells so no vision is possible at that point and is known as a blind spot this was a brief introduction about the human eye, its parts, and their functions stay tuned with byju's to learn more about human eye, structure of human eye and. Eyes are organs of the visual system they provide organisms with vision, the ability to receive and process visual detail, as well as enabling several photo response functions that are independent of vision eyes detect light and convert it into electro-chemical impulses in neurons in higher organisms, the eye is a complex. The cornea directs light rays into the eye and helps focus them on the retina the pupil is the opening in the colored part of the eye (iris) it allows light to pass to the lens the iris controls the size of the pupil in response to light outside the eye so that the proper amount of light is let into the eye continue reading below. Eyes are made of several different parts this part covers the surface of the eyes except at the very front most of the reflection takes place through cornea, aqueous humour and vitreous humour and the lens merely function to focus the image on. What's the most complex organ in the body some say it's the human eye made of many working parts, the human eye functions much like a digital camera here's how it works light enters the eye through the cornea, the clear front surface of the eye, which acts like a camera lens the iris works much like the diaphragm of. This article gives you information on the parts of the human eye, its functions, and the working strategy of the eye as a whole.

The iris is a diaphragm of variable size whose function is to adjust the size of the pupil to regulate the amount of light admitted into the eye the iris is the coloured part of the eye (illustrated in blue above but in nature may be any of many shades of blue, green, brown, hazel, or grey) more about the iris lens the lens of. Parts of the eye here i will briefly describe various parts of the eye: sclera image from the sclera is the white of the eye don't shoot until you see the graph on the right shows the optical density (-log transmittance) of the lens as a function of wavelength the curves show the change in. To better understand a student's vision, it is important to know how each part of the eye contributes to a person's ability to see each area of the eye has an important role and must function properly in order for the eye to function properly the following is a quick lesson in the structure and functions of the eye. The main part of the eye is the eyeball each eye is shaped like a ball and its full size is about 25 cm (1 inch) in diameter the inside of the eye contains a clear, jelly-like fluid that helps support the eye and maintain its shape in the front of the eye this fluid is more watery and called aqueous humour the fluid in the back of.

This resource worked well as a note taking lesson furthermore the children also explored braille and who uses it parts of the human eye and their functions. Play this quiz called unit 5 part 3 - eye parts and their functions and show off your skills. The iris - the pigmented part the cornea - a clear dome over the iris the pupil - the black circular opening in the iris, which lets light in the sclera - the white part the conjunctiva - an invisible, clear layer of tissue covering the front of the eye, except the cornea just behind the iris and pupil lies the lens, which helps to focus.

When it's dark, the iris in the pupil is enlarged or dilated, to maximise the amount of light entering the eye after receiving the correctly focused light, the retina's job is to analyse colour, intensity and form to transmit these as electric impulses to the brain the optic nerve connects various parts of our brain so that our emotions,. Iris the iris is the colored part of the eye although it might seem purely cosmetic, the iris actually functions to adjust the size of the pupil it has muscles that contract or expand depending on the amount of light the pupil needs to process images lens the lens exists behind the pupil and is responsible for allowing your eyes. The different parts of the eye play an important role this section contains a brief description of the main parts and how they work. Learn about all the different parts of your eye and their functions the more you know about your eyes the better you can protect them robertson optical.

Eye diagram the eye – one of the most complex organisms in the human body it is made up of many different parts working in unison together in order for the eye to work at its best, all parts must work well collectively to understand the eye and its functions, it's important to understand how the eye works, see below. Part names lens retina ciliary muscle optic nerve pupil cornea iris functions contains cells that detect light opening to the inner eye controls the size of the pupil focuses image of object controls shape of lens transmits information to brain outermost transparent layer of eye, begins focusing process.

  • There are 6 sets of muscles attached to outer surface of eye ball which helps to rotate it in different direction four sets structurally two eyes are separated but some of their activities are coordinated so that they functions as a pair it forms a slight bulge at the front and covers an anterior 1/6 part of sclera.
  • The iris of the eye functions like the diaphragm of a camera, controlling the amount of light reaching the back of the eye by automatically adjusting the size of the pupil (aperture) the eye's crystalline lens is located directly behind the pupil and further focuses light through a process called accommodation, this lens helps.

An overview of how the many parts of the eye work together to produce clear vision. Eyes are animal organs that are specialized for sight these may be as simple as proteins or cells which can tell light from darkness – like the “eyes” found in many microorganisms – or they may be complex assemblies of lenses, filters, light- sensitive tissues, nerves, and support structures. Even though the eye is small, only about 1 inch in diameter, it serves a very important function -- the sense of sight learn about the to produce an image parts of the eye although the eye is small, only about 1 inch in diameter, each part plays an important role in allowing people to see the world anatomy of the eye. Getting to know your eyes: different eye parts and their functions for such a small organ, the eye is a complicated part of the human anatomy—in fact, it might even be the most complex organ in your body after your brain some parts of your eye work hard to keep infection, dust, and other damaging substances out of.
