Eye

The eye is one of the significant special sensory organs that is responsible for vision. Through observation, we handled a cow’s eye and discerned our findings to our knowledge of a human’s eye. A cow’s eye has similarities, such as the overall layers of the eye like the sclera, choroid, and retina layer, to that of a human’s eye. Also the structures and organs contained within these layers. Also, we discovered many other anatomical structures that are much the same to a human's eye during the dissection. We were able to perceive the size of the eye and the shape of the pupil despite some differences. The overall structure and function is relatively the same as a human. This lab is designed to help students learn, and observe how the cow…

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…

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,…

younger looking skin, here is a new product, called Adaptive Eye Complex that promises to provide wonderful results.…

INTRODUCTION An extensive research was conducted to answer the question; How can the procedure of LASIK eye surgery be modified to prevent the potential side effects? This question is attempted answer through various research methods such as interviews with experts and relevant secondary research. Laser Vision Correction is a great alternative to glasses and contact lenses. The three main types of Laser Vision Correction are LASIK, PRK and LASEK (Thompson, 2016). The Laser Vision Correction…

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…

One of the most common eye injury occurring while playing sport is the scratch of the cornea or corneal abrasion in medical term.This injury consist of the scratching of the cornea by the finger or the fingernail of a player.An abrasion can be small or large depending of the gravity of the scratching.This type of injury ensues when the corneal epithelium is abraded and it is more common in basketball (Brummit & Ericksson p.150) where the players in general without face protection are…

Pax6 is vital for proper eye development Eyes are essential organs for processing and interpreting sensory information in the environment, making them crucial features for many organisms to survive. The eye serves many functions, most of which are associated with a specific structure of this organ. For example, the lens, cornea, and iris are necessary for the optic capabilities of the eye. Light sensing is performed by photoreceptors located in the retinal pigmented epithelium. Transmission by…

The structure of the eye contains several complex structures that make the eye like so of a camera. Without using complex equipment to view all parts of the eye or dissecting it, one can see three structures of the eye: the sclera, the iris, and the pupil. The white part of the eye is known as the sclera which is the outer most part, that helps the eye maintain its shape and protects the eye from injury. The black dot one can see in the middle of the iris is known as the pupil. The pupil is in…

From what I have read in “ The Mind’s Eye”, I think that every blind person’s experiences are different. The author uses John Hull, Zoltan Torey, and Sabriye Terberken as examples, the three have a drastically different experience when it comes to their inner eyes. Sacks says that the visual cortex or the inner eye is what gives you mental pictures of what things look like in your head. To explain, a person can picture what a relative or peer looks like, without having to see them because you…
