The Study of Myopia and Photorefractive Keratectomy Myopia is defined as nearsightedness, which exists when the refractive elements of the eye (cornea and lens) place the image in front of the retina. The myopic condition is common in infants but generally levels off to normal vision as the infant ages (Vander & Gault, 1998). Myopia occurs in about 25% of the adult U.S. population. Many adults use corrective lenses or contacts to correct their myopic vision to 20/20 vision (Drexler et al., 1998). Many people find contacts or glasses hindering in their personal and/or professional lifestyle. For example, military pilots cannot wear glasses while flying and some firemen may find glasses too dangerous to wear during a rescue attempt. There is refractive surgery available to correct myopic eyes, like Photorefractive Keratectomy (PRK). Why do people have myopia, what can be done to correct myopia, and what are the results of corrective surgical procedures? These are a few questions that will be addressed and analyzed. For an eye to focus correctly on an object, it must be placed in a certain position in front of the eye. The primary focal point is the point along the optical axis where an object can be placed for parallel rays to come from the lens. The secondary focal point is the point along the optical axis where in coming parallel rays are brought into focus. The primary focal point has the object's image at infinity, where as the secondary focal point has the object at infinity. For people who have myopic eyes, the secondary focal point is anterior to the retina in the vitreous. Thus, the object must be moved forward from infinity, in order to be focused on the retina. The far point is determined by the object's distance where light rays focus on the retina while the eye is not accommodating. The far point in the myopic eye is between the cornea and infinity. The near point is determined by which an object will be in focus on the retina when the eye is accommodating. Thus, moving an object closer will cause the perception of the object to blur. The measurement of these refractive errors are in standard units called diopters (D). A diopter is the reciprocal of a distance of the far point in meters (Vander & Gault, 1998). The myopic condition manipulates these variables in order to ultimately make a nearsighted individual.
Three equals one. Out of all of the statements made by the Christian faith, perhaps none is more confusing. The Doctrine of the Trinity has been questioned for decades and many Christians do not even understand it. Colin E. Gunton argues that this does not have to be so. Instead, he calls the Western Church to learn from Eastern Orthodoxy and allow Trinitarian thinking to permeate every aspect of the church. It is when the Western Church embarrasses “The Forgotten Trinity” (the name of the chapter) in thinking and in worship, that we not only learn the nature of God, but how we should live in light of it.
Krostenberger and Swain (2008) from the patristic period until today, John's Gospel has served as a major source of the church's knowledge, doctrine and worship of the triune God. Among all New Testament documents the Fourth Gospel provides not only the most raw material for the doctrine of the Trinity, but also the most highly developed patterns of reflection on this material—particularly patterns that seek to account in some way for the distinct personhood and divinity of Father, Son and Spirit without compromising the unity of God. While there have been recent, fine studies on aspects of John's doctrine of God, it is surprising that none summarises and synthesises what John has to say about God as Father, Son, and Holy Spirit. In order to fill this
Eyeglasses have two main lenses. This includes a convex lens for nearsightedness, and a concave lens which is for farsightedness. With both lenses the light hits the glasses and bends inward or outward (depending on your circumstances; nearsightedness or farsightedness) According to LL. Woodward, many people say that contact lenses fulfill both nearsightedness and farsightedness. “Thanks to the advent of multifocal contact lenses, people with both vision conditions-presbyopia and myopia-now have the option, and the freedom, to choose to wear contact lenses only to improve their vision” - LL. Woodward. From my recent questioning to students with contacts, there are two different types of contacts; one is to sleep with and you can see the rest of the day without them and ones that you wear throughout the day.
In the Old Testament everything is scarttered and it is hard to explain the exact meaning of the word trinity. However, in the Old Testament, they set up the idea of the trinity. God is the creator of this universe and he created this world by speaking his word and sending out his spirtit. Bavinck wrote that God’s “word” is the objective principle of creation and his “spirit” is the subjective principle. According to him, the world came into being by threefold causes, the word of God, word hypostatized as wisdom and the spirit of God. In other word, the Old Testament refers to God's word, his spirit, and Wisdom. This t...
“The practice of baptism in the name of the Father, the Son and the Holy Spirit in the second century propelled the development of the trinitarian theology” (LaDue 48). According to Collins, the trinity can be defined by three statements “1. There is only one true God. 2. This one true God exists as three distinct persons. 3. Each person is fully divine” (Collins 29-31). The three people that make up the trinity are the Father, the Son and the Holy Spirit. First there is the Father. There are many Bible passages where God is referred to as the Father, this can be concluded because He alone created all things and His first human creation, Adam, was called the son of God. Jesus is God’s son and he was sent by his father, the Father, to offer humanity salvation from their sins. The “God of the Israelites reveals himself as a distinct, unique, superior deity who is always there. God’s being there is what defines him” (LaDue 14). The Israelites sometimes see the God Yahweh as an imitation of the trinity in the old testament, but they do not have distinct leveled personalities. Although God is distinct and unique, the idea that He is superior can be a false assumption as all the persons of the trinity have equal power and divinity. Another person of the trinity is the Holy Spirit. Yes, the Holy Spirit is a person. This is a common misconception of the
Jekyll and Mr. Hyde’s appearances. As a stereotypical depiction of good and bad, the evil persona is ugly and appears to be suspicious at first look. Dr. Jekyll, the good personality, is handsome and seems to be kind-hearted. Stevenson vividly describes Hyde, “…so ugly that is brought out the sweat on me like running...” (3). Hyde’s hairy, animal-like appearance symbolizes how society compares his evil and impure personality to that of an animal. The comparison accentuates the difference between Dr. Jekyll and Mr. Hyde, showing how separate a man’s two personality could be. Stevenson’s usage of appearance to define their contrasting personalities. Stevenson utilizes the individuals’ appearance to completely describe the dual personality of Dr. Jekyll and Mr. Hyde. Stevenson also uses the stereotypical appearance of good man to symbolize his kind acts versus the murderous evil acts that Mr. Hyde commits. The author uses the characters’ appearance as well as their appearances to symbolize the battle between pure and
The Strange Case of Dr. Jekyll and Mr. Hyde, written by Robert Stevenson is one of the most explicit written novels in the study of literature. The novel explains the double figure of man that relates to duality of man ‘ s nature. Dr. Jekyll is over rewriting the rules of nature by creating another character in him that will satisfy his deepest thought of evil doing. The author is specific in the aftermath of Dr. Jekyll decision, the essay will explain every man has good side and a bad side and Dr. Jekyll triggered his bad side by creating Mr. Hyde.
The Trinity is not a biblical teaching , how is she become a doctrine of Christianity? For many, it was mad...
The Christian’s monotheistic God consists of three parts: the Father, the Son, and the Holy Spirit. Although they all exist in different beings , the Father, Son, and Holy Spirit make up God; they create the Holy Trinity that lives in Him. Many have proven the Holy Trinity to be true through biblical and historical evidence, so no person can deny this fact. However, many theologists like to state the Trinity is a pagan concept adopted by Christianity, and since no one mentions the word “Trinity” in the Bible, the idea of the Trinity is disputable. Nonetheless, the Trinity still makes up God, and God is still monotheistic; no one can disprove this reality.
“Art” is an interesting and complex term. When evaluating the subject and trying to have a general understanding of what art is, one has to have a clear awareness of basic art theory and common art-related knowledge. In a textbook, art could be described as the expression or application of human creative skill and imagination producing works to be appreciated primarily for their beauty or emotional power; it could also be bluntly described as various branches of creative activity, such as painting, music, literature, and dance. I agree with this definition to an extent—art is more than just a medium of appreciation. Art, in my opinion, is more about the message between the artist and the viewer.
Mr. Hyde is purely evil. He is described to be smaller, younger, ugly, and hairier; he is considered to be villainous and evil. Stevenson compares him to a monkey. The monkey symboliz...
The patient is a 43 year-old female insurance sale agent who came to the clinic for annual eye examination. She complained from symptoms of ocular irritation and burning when she wakes up in the morning. She felt ocular dryness in the afternoon and the eyes look red. She has also noted different height of her eyelids when putting make-up on. She denied significant problems with driving, TV watching, computer use or reading. She also denied flashes, floaters or diplopia. The patient was myopia with no prior eye surgeries, previous history of eye trauma, amblyopia or strabismus. She did not use any medication. The past ocular family history was negative. Social history was negative, too.
Robert Louis Stevenson’s Strange Case of Dr. Jekyll and Mr. Hyde was immediately popular among readers, due to its terrifying introduction of “double-identities,” upon its release in 1886. While there has been much debate over Dr. Jekyll and Mr. Hyde as being representative of two separate bodies or, alternatively, two beings within one body, the resolution of two separate identities is clear. Mr. Hyde’s identity is the socially marginalized, racially charged, and devolved physical embodiment of Dr. Jekyll’s fear of growing class separation and “biological degeneration and racial decline, sparked by Darwin’s evolutionary theory” (Sborgi 149).
“The Mosaic Revelation, as compared with the cosmic revelation, represents a great advance in the knowledge of the true God; but it represents, nevertheless, nothing more than a stage” (Danielou, 121). This revelation reveals to us the term Trinity of Persons. The trinity of Persons is the mystery of God. The trinity is composed of the Father, the Son, and the Holy Spirit. The three elements of the trinity are also seen as one. The oneness in three opens the door for the mystery in Christianity.
