Eye color

Our eyes work like a camera. Just like a camera lens focuses our cornea focuses light on the membrane called the retina. The cornea is transparent. It's found in the front of the eye and it helps focus light. Behind the pupil is a colorless, see threw structure called the crystalline lens. A clear fluid called the aqueous humor fills between the cornea and iris. The cornea focuses most of the light and then it goes through the lens. Behind the cornea is a colored, ring shaped membrane called…

and eventual confession. A psychopath becomes mentally unstable, as he begins to obsess over his master’s pale blue eye. Furthermore, the psychopath comes to believe that the eye is…

a Barbie that had brown hair and green eyes. I wanted a doll that represented me, one that looked like me or at least seemed like the person I wanted to grow up to be. I don’t remember my age when I saw my first "black" baby doll, but I do remember my mother’s reaction to it. I thought the baby was beautiful and could not comprehend her aversion to the doll. It was after all just a doll. I was naive enough at that point to see the toy through the eyes of a little black girl and was quite…

few weeks reading Toni Morrison's novel " The Bluest Eye," I have noticed how the society had a major impact on the character's daily lives. The community had more of a bigger impact on Pecola Breedlove's life. The community where Pecola lived in, which were mostly African-American did not care for Pecola and that caused for her downfall in the end. People in the community think there is only one type of beauty which is having "pale skin, blue eyes" . Pecola most certainly does not fit that…

Cataracts occur when the lens becomes blurry, causing vision to be hazy and distorted. The lens is between the lens and pupil and refracts light that comes into the eye, which helps us to see and focus on objects. Those who experience cataracts, feel like they are looking through a foggy window. There are four main types of cataracts, traumatic cataracts, congenital cataracts, secondary cataracts, and radiation cataracts. Traumatic cataracts can occur from ocular injury, which will disrupts lens…

handles light. As I get to the path light takes as it enters our eyes I will point out four mechanisms that have to function in order for us to see. Each of our eyeballs have six muscles that attach them to our skull. Four of these muscles pull straight and are called rectus muscles. Two of these muscles pull on an angle and are called oblique muscles. The first mechanism is the coordination of these muscles (both eyes) so that our eyes move together. As we open our eyelids (provides protection…

eased the sheets down to expose her shoulders, Isla took a slow breath in, confused by the deep voice pressed tightly against her ear. Melatonin and adrenaline both rushed through her veins, causing the woman to jolt in the very next instant. Green eyes flashed open, a startled grunt trembled beneath the grip of his heavy hand and all she could do was react on instinct as her mind struggled to…

Fear. What is fear? To some fear is nothing more than an emotion that we feel whe we feel unsecure about something. To others it's a whole different story. Imagine having everything in the world that you ever wanted, and in the blink of an eye it's all gone. One can never get over the feeling of loosing someone special in they're life. To know that the person that gave you everything is no longer around to help you continue in life. This is my fear, to lose more people that mean so much to me.…

transparent tunnel that traces its path through the vitreous body of the eye, spanning the optic nerve disc to the lens. In an adult person, the hyaloid canal carries lymph to help change the volume of the lens. When the lens expands, the hyaloid canal compresses, so that the eye’s internal pressure and volume remain constant (Merriam-Webster). Optic nerve: A part of the central nervous system, the optic nerve connects the eye to the brain, carrying electrical signals formed by the retina to…

photoreceptors in the human retina. The retina is a tissue lining inside of the eye that absorbs light, processes images, and sends visual information to the brain. There are millions of receptor cells in the retina that control the sensitivity to light. The rods and cones are two types of receptors that are found in the retina. They both play an important significant to the luminosity humans use to see. When light is passed through the eye, rods and cones are used to determine what you see…
