    To see how the eye works: Let’s understand different parts of the eyes which help us see images.

    Cornea: Light which we see enters through the cornea, the straightforward external covering of the eye. The eyeball is adjusted, so the cornea goes about as a focal point. It helps to twists or refracts light.

    Aqueous Humor: The liquid which is present underneath the cornea has an organization like that of blood plasma. It assists with molding the cornea and gives sustenance to the eye.

    Sclera: The sclera is normally alluded to as the “whites” of the eye, which is visible to us when we look ourselves into the mirror. This is a smooth, white layer outwardly, yet within is earthy colored and contains grooves that help the ligaments of the eye join appropriately. The sclera gives construction and wellbeing to the inward operations of the eye, but at the same time is adaptable so the eye can move to search out objects as essential.

    Iris and Pupil: Light goes through the cornea and Aqueous humor through an opening called the pupil. The size of the understudy is controlled by the iris, the contractile ring that is related to eye tone.

    Conjunctiva Glands These are layers of bodily fluid that help keep the outside of the eye wet. If the eye dries out it can get itchy and excruciating. On the off chance that the conjunctiva organs become tainted the patient will create “pink eye.”

    Lens: While the greater part of the shining of light is finished by the cornea, the Lens permits the eye to zero in on either close or far off objects. Ciliary muscles encompass the focal point, unwinding to level it to picture far-off articles and contracting to thicken the focal point to picture close-up objects.

    Retina: The light engaged by the Lens will be sent onto the retina. This is made of bars and cones organized in layers, which will communicate light into synthetic substances and electrical heartbeats. The retina is situated toward the rear of the eye and is associated with the optic nerves that will send the pictures the eye sees to the cerebrum so they can be deciphered.

    Vitreous Humor: A specific distance is needed to focus on light. It is a straightforward watery gel that upholds the eye and takes into consideration this distance.
