EXECUTIVE SUMMARY THE COMPANY Concept: Make and market red-tinted contact lenses for egg-laying chickens, altering their behavior so they will fight less, eat less, and produce more eggs -- increasing egg-ranch profitability Projections: Eventual pretax net margins of 25%; 1989 sales of $329,000; 1992 sales of $24 million Hurdles: Persuading historically conservative egg farmers, operating on thin margins, to risk money up front for an unproven product; sustaining the company in the face of slower-than-expected
patient orders a pair of glasses they first choose a set of frames that suits them. The patient must have a prescription must be written by an optometrist which states the needed lens power and pupil distance (PD). Lenses in the needed power are either ordered or taken from stock. These lenses come from the factory as uncut round blanks approximately four inches across. Edging is the process of cutting these optical lens blanks to fit frames, producing a pair of glasses. Equipment There are four
is more oval than round, light does not focus properly on the back of the eye, also known as the retina. Astigmatism is not a disease, but is actually a vision condition that is quite common--only moderate to highly astigmatic eyes need corrective lenses. The signs and symptoms of severe astigmatism are blurred or distorted vision. For mild astigmatism the symptoms are headaches, eyestrain, fatigue, and blurred vision at certain angles. The causes of astigmatism are unclear. It may be genetically
refracting, or bending, it with glass lenses. The devices that are used to do this, however, vary, depending on the wavelength or type of radiation being studied. Optical Telescopes The first telescope developed, and the one most widely used, is the optical telescope, which gathers visible light radiation. There are three basic types of optical telescopes: refractors that use lenses, reflectors that use mirrors, and catadioptrics that use a combination of both lenses and mirrors. The refracting
first. Here is one authors opinion. Lippershey was a Dutch spectacle marker during the early 17th century (approximately 1600). He was one of the first who created the "looker" (now called telescope) by placing two pieces of lenses together. The discovery that placing lenses together can magnify images were made by children who took Lippershey's spectacles and looked at a distant church tower. One of the most influential scientist associated with the telescope has to be Galileo. He took the design

Most microscopes, including those in schools and laboratories today, are optical microscopes. They use glass lenses to enlarge, or magnify, an image. An optical microscope cannot produce an image of an object smaller than the length of the light wave in use. To see anything smaller than 2,000 angstroms (about 1/250,000 of an inch) a wave of shorter length would
the stage, the light passes through the eyepiece lens so that it is clearly visible to see. Most microscopes consist of twelve parts; the eyepiece lens, the tube, the arm, the base, the illuminator, the mirror, the stage, the turret, the objective lenses, the rack stop, the condenser lens and the iris. Every part of a microscope has a very important responsibility in order for people to see smaller things clearly. For example the eyepiece lens is what you look through to observe. An illuminator is
towards me. I turned round and threw them to Raymond, who was behind me. Unfortunately Raymond wasn’t expecting this and he missed them. The glasses fell on the cement floor and both lenses were shattered. One or two people laughed, but then the room fell silent. They had been expensive glasses with metal frames, and the lenses were tinted. Vincent had to wear them in the sun as well as indoors. “ Vincent, I’m sorry,” I apologized lamely. “ I meant it as a joke…” Vincent didn’t reply. I’ll help

adaptation prohibiting her eyes from being seen. “...the glasses were surgically inset, sealing her sockets. The silver lenses seemed to grow from smooth pale skin above her cheekbones...” (Gibson 24) The eyes are said to be windows to the soul. Many emotions and states of mind are conveyed by the eyes. Molly, however, does not relinquish this power of perception to others. “The lenses were empty quicksilver, regarding him with an insect calm.” (Gibson 30) The mirrored sunglasses mask key characteristics
Dutch eyeglass makers invented the microscope in the late 1500’s. It consisted of a tube with lenses ground from rock crystal, and it magnified objects up to 9 times their actual size. 3. In 1665 the British scientist Robert Hooke published a set of drawings illustrating what he had observed with a microscope. 4. In the early 1670’s Anton van Leeuwenhook, a Dutch fabric-store owner, began to grind lenses as a hobby. He used handheld microscopes to examine materials such as pond water and blood. BIOLOGISTS
photographers and their talents. The photographs from twenty years ago were using nothing but a cheap old 35mm and came up with some incredible artistic shots. But those old cameras have been replaced by today’s photographers with the top of line cameras and lenses. The top two magazines in the skateboarding world today are Thrasher and Transworld Skateboarding magazine. Both of these magazines have been around since the early 80’s and have covered every angle of skateboarding
Because the eye is so complex, there are many questions that might come to mind when it concerns the break down or conditions that is brought upon the eye. 1st, What happens to the eye during the gradual age of time? 2nd, How do eye glasses or contact lenses influence the eye’s capability of seeing better? 3rd, In worse case circumstances, what occurs to the eye if there is trauma brought on like an accident that directly affects the way a person sees or if the eye is diagnosed with a disease that will

but rather spiritually as she has turned into a killing machine. The only true way to describe it is cold-blooded. Her icy nature is revealed, once again, through the use of the color gray. Her eyes, or what is left of them, used silver, mirrored lenses. Just by her paratactic description, the reader syntactically knows her faults through her faulty vision. In addition to Molly, one other member of Case's team is flawed using the color gray. This is Armitage, or Corto. Armitage is merely a shell
University. MAJOR ACCOMPLISHMENTS Shortly after college he began to study optics and the construction of telescopes, and wrote his first book, Optica Promota ^1. In 1663 James went to London where he published Optica Promota, which discussed topics such as lenses, mirrors, reflection and refraction, paralax and transits. Optica Promota also discussed Gregory's most famous invention, the reflective telescope. It later became known and the Gregorian Telescope. However, at the time the telescope was only discussed
Karl Popper and Falsifiability Karl Popper's claim that "the criterion of the scientific status of a theory is its falsifiability" is a clearly viable statement. This is a natural extension of his idea about how scientific knowledge is increased (Edwards, 1967). In an attempt to define science from pseudo-science, Popper states that the growth of scientific knowledge begins with an "imaginative proposal of hypotheses" (Edwards, 1967). Then, the scientist must search for illustrations or situations
rays are reflected in innumerable directions. In order to capture an image onto film one must be capable of controlling the light rays that enter the camera. This is done through the lens. The lens consists of a mixture of converging and diverging lenses that bend the light so it reaches the film as a real image. The light that passes through the upper po... ... middle of paper ... ...of the light from the scene behind the subject must bend more to reach the film, causing the background to be
windshields, he knew that his unique glass could save lives. Unfortunately, automakers were uninterested in the costly safety glass for windshields. It was not until the outbreak of World War I that safety glass found its first application: as the lenses for gas masks. After automobile executives examined the proven performance of the new glass under the extreme conditions of battle, safety glass’s major application became car windshields. It was very dangerous when something hit your car, the glass
