    Vision is the most fundamental of human senses. The human eye is a very complex and truly amazing organ.

    It is approximately one inch wide and deep, and 0.9 inches high. Human eyes allow us to appreciate all the beauty of the world we live in, to read and gain knowledge, and to communicate our thoughts and desires to each other through visual expressions , and arts. The front of the eye includes: iris (the pigmented part), cornea (a clear dome over the iris), pupil (the black circular opening in the iris, which lets light in), sclera (the white part), and conjunctiva (an invisible, clear layer, pf tissue covering the front of the eye, except the cornea).

    Just behind the iris and pupil lies the lens, which helps focus light on the back of the eye. Most of the eye is filled with a clear gel called the Viitreous. Light projects through the pupil and the lens to the back of the eye. The inside lining of the eye is covered by special light-sensing cells, together called the retina. The retina converts light into electrical impulses. Behind the eye, the optic nerve carries these impulses to the brain. The macula is a small sensitive-area within the retina that gives central vision. It is located in the center of the retina and contains the fovea. Eye color is created by the amount and type of pigment in the iris. Multiple genes inherited from each parent determine a person's eye color

    Vision is one of the most fundamental of human senses, so am I. I capture every moment in my life and enjoy seeing beautiful parts of the world with my eyes.

    I have a pair of beautiful big eyes with black iris and white sclera. I have thick eye lashes above my eyes. I can move my eye balls to the right and left, upward and downward, especially when I perform a pendet dance. Many people are amazed by my beautiful eyes.

    I always maintain my eyes health. I don't watch television or stay in front of a laptop for a long time. I also like consuming carrots to maintain my vision. I occasionally wear glasses when riding a bicycle to protect my eyes from dust.
