The eye is one of the most important and complex organs of the human body. An organ of sight,the eye has various components that help us in vision. In this article, Dr Somdutt Prasad — a renowned ophthalmologist and retinal specialist — explains the important parts of the eye.
Cornea
The cornea is the outermost layer of the eye. It has a dome-shaped surface that covers the eye's front part. It has no blood vessels and receives nourishment from tears and aqueous chamber. It protects the eye from germs and dust. The cornea cops up well with minor injuries. However, in case of a major injury it is vital to contact an eye surgeon immediately.

Retina
A light-sensitive layer of tissue, the retina receives the light focused by the lens and converts the light into neural signals on the brain. It processes the light through a layer of photoreceptor cells. Since it plays a vital role in vision, therefore, damage to it can result in permanent blindness.

Conjunctiva
The conjunctiva is a thin, moist membrane coating the inner surface of the eyelid. It lubricates the eyes through mucus and tears and helps prevent entry of microbes in the eyes. Tiny blood vessels nourish the conjunctiva. When it gets inflamed, it results in conjunctivitis.

Lens
Lens is a biconvex structure of the eye that, along with the cornea, helps refract light on the retina. By changing its shape, it changes the focal distance of the eye, thereby enabling it to focus on objects at various distances.
We must all take care of our eyes in every possible way and protect it from any kind of injury or infection.
