Human eye

Human eye model A three-dimensional FE model of the human eye has been made via the explicit dynamics finite element code LS-DYNA 970 (LSTC, Livermore, CA, United States) [30]. The morphological characteristics of the human eye (a normal/healthy male) along with intraconal and extraconal fats were obtained from Computed Tomography (CT). The donor declare his consent to use the CT images for medical research purposes. A total of 141 raw data images were obtained for the head with an especial focus on the eye. The data were analyzed and exported into the Digital Imaging and Communications in Medicine (DICOM) format. Subsequently, these data were imported into a Windows-based personal computer using MIMICS software (MIMICS 10.0, Materialise Inc.,…

The Human Eye One of the most composite and magnificent parts in the body is the human eye. Through eyes, people are able to visually see the world, and all of its wonders and spectacles. In the human body, “eyes are the second most complex organ in the body only behind the brain” (Butler, 2015). All over the world, people have various eye shapes, eye colors, and eye visions. However, unfortunately, there are some people who were either born blind or became blind due to the effects of old…

The magic of vision is incredible. Through the small window we are able to see the whole world. Eye is one of the five senses what human possess and majority would agree that it is perhaps the most important one. Many of us would be intrigued by the composition of the eye and even more by his interconnection with brain. How the eye actually works, his structure and the function will help us in better understanding how visual light is converted into our perception. The challenge of the image…

A study into the portrayal of eyes in the work of Jurek Zamoyski, Mark Powell and Alon Avissar (double exposure). Eyes are one of the most powerful and important aspects of being a human. They are extremely symbolic and hold various values for different cultures and religions. In art, Eyes often perceived as the physical structure and appearance and less often about what you see through them. I chose to look into how eyes are portrayed through multiple artists, which included Jurek Zamoyski,…

“A dog, maybe a monkey, only a rat— someone inhuman, less than human, maybe even the same— cries in the dark and cannot bear another moment of pain. He dreams of a place called home but waking remembers it is only a dream. Yet maybe they will think of you with the soap they use to wash away dirt, little sins they forget or choose to ignore, with the powders and shadows they wear to hide truths, or the polish they sweat over so their floors shine just so. Yes, the rest of the world, in its way…

1944 is a widely used test that predicts human ocular irritancy by using laboratory animals, primarily albino rabbits. A substance is applied directly into the albino rabbit’s eye or to the surrounding skin to identify its likely effect on the corresponding human tissues based on direct visualization (Mitjans, Infante & Vinardell, 2008). Due to advances in ocular technology, the precision, validity, need and relevance of the Draize test is being challenged (Wilhelmus, 2001). The Draize test is…

The two different types There are two types of eyes in the world of today. There are what one calls compound eyes and there are vertebrate eyes. Compound eyes also known as Arthropod eyes, can be traced back to an arthropod called trilobite. These ancestors didn 't have complex lenses like those of today but instead, their eyes and lenses were made of the same rock that made their skin - calcite. Compound eyes today contain many ommatidia (singular: ommatidium) which consist of a corneal lens,…

The other day, I was thinking about how amazing it is to be able to perceive the world around me. I understood that from the retina to the brain, perception goes from complex to extremely complex. In other words, being able to experience the real world is one of the marvelous opportunities that we have. This phenomenon starts with light getting in contact with the cornea continuing to the back of the eyes, to the retina, before light goes to the optic nerve and end up in the brain. This process…

grew furious as I gazed upon it." This quote from the Tell Tale Heart in which the narrator speaks of the old man's eye is just one of the many examples of how he is truly a mad man, a mad man with multiple psychopathic tendencies. He not only killed the old man that he liked so very much because of his sinister eye but he also cut him up into tiny pieces and hid him in the floorboard beneath his feet! The narrator didn't have a heart, he didn't feel sympathy or remorse for the old man when he…
