Color Blindness Check
Color blindness is an inaccurate term for a lack of perceptual sensitivity tocertain colors. Absolute color blindness is almost unknow.
http://www.geocities.com/Heartland/8833/coloreye.html

Extractions: Color Blindness W hen I was a kid in kindergarten, my parents never knew why I got low grade in identifying the color of crayons. Not until the day I was responsible for an Open Day project on color blindness in my secondary school did I noticed that I am one of the 'victim'. Though I was not blamed for the low grade then, restriction on choosing my job twenty years later frustrated me somehow. C olor blindness is an inaccurate term for a lack of perceptual sensitivity to certain colors. Absolute color blindness is almost unknow. There are three types of color receptors in our eyes, red, green and blue. We also have black and white receptors. They are more sensitive than the color receptors, that is why we have poor color perception in the dark.
Motion Induced Blindness
Demonstration of Motion Induced blindness Motion Induced blindness.From Michaels Optical Illusions Visual Phenomena
http://www.michaelbach.de/ot/mot_mib/

Extractions: Motion Induced Blindness From Michaelâs What to see On the right you see a rotating array of blue crosses and 3 yellow dots. Now fixate on the centre (watch the flashing green spot). Note that the yellow spots disappear once in a while: singly, in pairs or all three simultaneously. In reality, the 3 yellow spots are continuously present, honest! What to do You can use the slower/faster buttons to change speed. Disappearance persists down to surprisingly low speeds. [If there are no buttons on the right, please update your Flash player.] You can use the larger/smaller buttons to change size. Disappearance persists up to surprisingly large sizes. You can use the âback-col.â button to change the background colour. The yellow dots disappear into whatever colour the background has. The âdefaultsâ button at the top restores the standard settings. Comment Steady fixation favours disappearance, blinks or gaze shifts induce reappearance. All in all reminiscent of the Troxler effect, but stronger and more resistant to residual eye movements.
No Smoking
Smoking and macular degeneration, cataracts, loss of hearing, and loss of night visioin.
http://www.mdsupport.org/library/nosmoke.html

Extractions: One printed copy is permitted for personal use only. By Linda Kaspari Cigarette smoking reduces levels of plasma antioxidant, a substance in the blood stream, which protects retinal cells. Smoking causes the protective layer between the retina and blood vessels to erode, resulting in poor circulation, irritation and scarring. Smoking is damaging to the blood supply. Smoking exposes the body to free radicals which causes cellular damage and can cause poor circulation of nutrients to the retina and lens. Carotenoid levels and vitamin C blood concentrations are substantially reduced. Smoking oxidizes cholesterol, causing fat to build up in the arteries. This leads to heart attack, stroke, and probably macular degeneration. Researchers think smoking contributes to the incidence of some types of cataracts. "What makes us suspect this is the consistency of studies all over the world," says Robert Sperduto, M.D., chief, epidemiology branch of the National Eye Institute. "If there's one thing people can do to improve their general health, including the health of their eyes, it is to stop smoking," says Dr. Sperduto. Carbon monoxide from cigarette smoke creates a hypoxic effect, it is clear that hypoxia will degrade night vision. (Hypoxia is a state of oxygen deficiency in the body which is sufficient to cause an impairment of function. The inadequate oxygen transport or the inability of the tissues to use oxygen causes hypoxia.)

Blindness - Wikipedia, The Free Encyclopedia
The term blindness also applies to partial visual impairment In North Americaand most of Visual impairment includes low vision as well as blindness.
http://en.wikipedia.org/wiki/Blindness

Extractions: Over US$225,000 has been donated since the drive began on 19 August. Thank you for your generosity! Blindness Blindness can be defined physiologically as the condition of lacking visual perception . The definition as it applies to people thus legally classified is, however, more complex. "Blindness" also applies to partial visual impairment: In North America and most of Europe , legal blindness is defined as vision of 20/200 (6/60) or less in the better eye with correction. This means that a legally blind individual would have to stand 20 feet from an object to see it with the same degree of clarity as a normally sighted person could from 200 feet. In many areas, people with average acuity who nonetheless have a visual field of less than 20 degrees (the norm being 180 degrees) are also classified as being legally blind. Approximately ten percent of those deemed legally blind, by any measure, are fully sightless. The rest have some vision, from light perception alone to relatively good acuity. Those who are not legally blind, but nonetheless have serious visual impairments, possess low vision By the 10th Revision of the WHO International Statistical Classification of Diseases, Injuries and Causes of Death
Color Blindness
Identifies many conditions which can cause color problems. Includes informationon diagnosis, treatment, and prognosis.
http://www.chclibrary.org/micromed/00043350.html

Extractions: Normal color vision requires the use of special cells, called cones, located in the retina of the eye. There are three types of cones, termed red, blue, and green, which enable people to see a large spectrum of colors. A defect or deficiency of any of the types of cones will result in abnormal color vision. The following are three basic types of color blindness: Red/green color blindness. Red/green color blindness is the most common deficiency, affecting 8% of Caucasian males and 0.5% of females. People with red/green color blindness can often distinguish red or green if they can visually compare the colors. For example, they can pick out red or green from a package of colored pencils. However, if handed a red pencil, they cannot tell what color the pencil is. Blue color blindness. Blue color blindness, which is rare, is an inability to distinguish both blue and yellow. Blue and yellow are seen as white or grey. Although as many females as males have this deficiency, it usually appears in people who have physical disorders, such as liver disease or diabetes mellitus. However, it is not uncommon for young boys to have blue/green confusion that becomes less pronounced in adulthood.
What's Color Blindness?
You might think being colorblind means you can t see any colors. But that s nottrue. Find out more in this article for kids.
http://kidshealth.org/kid/talk/qa/color_blind.html

Extractions: If your clothes don't match, someone might have teased you about being color-blind. But some people really are color-blind. It doesn't mean they can't see any color at all, like a black and white movie. It means that they have trouble seeing the difference between certain colors. (Check out the image on the right to see how well you see colors.) Being color-blind can make it tricky to match your shirt and pants, but it's not a serious problem. People who are color-blind can do normal stuff, even drive. Most color-blind people can't tell the difference between red or green, but they can learn to respond to the way the traffic signal lights up. The red light is generally on top and green is on the bottom. Cones and Color To understand what causes color blindness, you need to know about the cones in your eyes . Cones in your eyes? Yes, but they're very small. These cones are cells on your retina, an area the size of a postage stamp that's at the back of your eye. You have "red," "blue," and "green" cones, which are sensitive to those colors and combinations of them. You need all three types to see colors properly. When your cones don't work properly, or you don't have the right combination, your brain doesn't get the right message about which colors you're seeing. To someone who's color-blind, a green leaf might look tan or gray.
GUUUI - Navigation Blindness
GUUUI the interaction designer s coffee break, with daily postings and quarterlyarticles about interaction design.
http://www.guuui.com/issues/01_05.php

Extractions: How to deal with the fact that people tend to ignore navigation tools Most web development projects put a lot of effort into the design of navigation tools. But fact is that people tend to ignore these tools. They are fixated on getting what they came for and simply click on links or hit the back button to get there. The navigation tools that have become standard on the web seem to be designed with the ambition to give users the option to go anywhere from everywhere. Menus with links to all the main sections are discretely placed to the left or at the top throughout the site and fold out and drop down to reveal where you are and where you can go. In this way, every page on a website becomes a major traffic junction, where road signs point you in all directions. But people have specific destinations in mind. Above all, they need clear signage along the way to their destinations. Two of the world's most well-respected usability experts Jakob Nielsen and Mark Hurst agree on at least one area: Users tend to ignore navigation and don't care where they are in a site structure. They are highly goal-driven and follow a very simple click-link-or-hit-back-button strategy when navigating websites.
How The Edgar Cayce Readings Helped With Blindness
How the Edgar Cayce readings helped me overcome blindness caused by optic neuritis.
http://www.cayce.com/blindnesscoraino.htm

Extractions: At the age of 27, I suddenly lost the sight in my left eye due to optic neuritis. I went to three ophthalmologists including the head neuro-ophthalmologist at NYU hospital. I was offered only steroids as a treatment, which I was afraid to take because my body is extremely sensitive, and I was concerned about the side effects. Fortunately, a family friend told my mother to get me to a chiropractor immediately. I was a member of the Edgar Cayce organization, the Association for Research and Enlightenment , and I was aware that Edgar Cayce recommended chiropractic adjustments for all sorts of ailments, and that the A.R.E. had a listing of chiropractic members. I decided that I wanted to be treated by a chiropractor who would treat me with the Cayce remedies for blindness. I called the A.R.E. and was given the name of Dr. John Pagano (author of Healing Psoriasis ) in Englewood Cliffs, New Jersey. I called him immediately, and he told me to come over right away. My mother agreed to drive me to his office, although she had always been skeptical about my interest in the Cayce readings. When we met Dr. Pagano, he told me that he had successfully treated a woman the previous year, who had been blind in both eyes for several months due to optic neuritis. Dr. Pagano told me that he could make no promises, but he would treat me the same way he had treated her, according to the Edgar Cayce readings.

CHICAGO, Illinois (Reuters) Hundreds of thousands of people could benefit from vitamin supplements shown to help prevent macular degeneration, a condition that is the leading cause of blindness from age 65, a study reported. In 2001, researchers announced they had found a reduced risk of advanced age-related macular degeneration and vision loss for test subjects who had been given high-dose antioxidant supplements vitamins C, E and beta carotene as well as zinc or zinc oxide. In Monday's report, researchers at the Johns Hopkins Medical Institutions in Baltimore tried to estimate how many people in the United States alone would benefit from increasing supplement use. They concluded there are 8 million Americans at least 55 years old thought to be at high risk for the problem. If all the people at risk took the supplements used in the earlier study, more than 300,000 of them would avoid advanced macular degeneration and any associated vision loss during the next five years, the study said.

Conditioned Ethical Blindness, By Peter Singer & Lori Gruen
Excerpted from Lori Gruen and Peter Singer, 'Animal Liberation A Graphic Guide' (London, 1987).
http://www.utilitarian.net/singer/by/1987----.htm

Extractions: Conditioned Ethical Blindness Peter Singer Excerpted from Animal Liberation: a Graphic Guide , London, 1987, pp. 78-80 How can otherwise decent citizens do these things? How can they become so insensitive to what they are doing? Don Barnes, who spent sixteen years as a biomedical scientist experimenting on animals, and now heads the Washington, DC office of the National Anti-Vivisection Society, calls the state in which he used to do his work 'conditioned ethical blindness'. From his early years growing up on the farm, and continuing into his time as a Ph. D. student, Barnes accepted the idea that non-human animals exist to serve human purposes. As a student of psychology, he was also taught a whole new vocabulary which served to distance the experimenter from the animal. The monkeys on which he worked became 'research subjects'; the electric shocks he gave them were called 'negative reinforcement' and their vain efforts to escape were classified as 'avoidance behaviour'. As Barnes says: 'During my sixteen years in the laboratory the morality and ethics of using laboratory animals were never broached in either formal or informal meetings prior to my raising the issues during the waning days of my tenure as a vivisector'. Don Barnes is not the only one to have escaped his conditioning. In 1977 the magazine

EMJA: Mitchell Et Al, "Smoking Is A Major Cause Of Blindness"
Editorial in a health journal considers the scientific and policy merits of a new pack warning.
http://www.mja.com.au/public/issues/171_4_160899/mitchell/mitchell.html

Extractions: Health warnings on Australian tobacco products have been mandated through federal legislation since 1973, being updated in 1987 and 1995. Issue of the current warnings followed a detailed study examining the likely impact of prototypes, particularly on youth. The warnings address general health ( "Smoking kills" ), lung cancer, heart disease, addiction, low infant birthweight, and harm to others through passive smoking. The adoption of health warnings was vigorously opposed by the tobacco industry, whose internal research indicated that many smokers disliked their prominence and more detailed content. Internationally, the track record of the tobacco industry has been to oppose more "hard-hitting", specific warnings in favour of blander, more general warnings such as "Smoking reduces your fitness" . We propose a new "hard-hitting" cigarette pack warning. Recent population-based cross-sectional data from four countries including Australia
