Home Products Projects Research Demos Contact 1 in 12 people suffer from some sort of color deficiency CBC: Color Blindness Check For this little tool we got our inspiration from Cal Henderson , who made a page showing the effects several types of color blindness can have on the readability of a website. We thought Cal did a nice job and since we are doing two projects where accessability for people with a disablility is a major issue, we thought we might add a little of our own to his work. CBC is a little tool we made for people to test their webpages with. It re-colorizes any webpage you like into a palette that closely resembles the typical palette available to a person having a red/green color vision deficiency. (This is the most common color blindness. Comparing Cal Henderson's data, it comes closest to Protanopia.) Below we describe two ways to use CBC. Both require Internet Explorer 5.0 or more on a Windows PC. There is some chance that even then CBC will not work... in that case you need to install the latest DirectX drivers.

Antibiotics could provide a cheap, safe and effective way of wiping out the disease, which is caused by a parasitic worm. Scientists from the United Kingdom, Cameroon and Germany, say their experiments show that using antibiotics to kill bacteria living on the parasite, also kills the parasite itself. This is an important step in finding a cheap, safe and effective way of curing the infection Professor Alexander Trees, Liverpool School of Tropical Medicine River blindness, or Onchocerciasis, causes severe itching, disfiguring lesions and lesions of the eye that can cause blindness. It is most prevalent in sub-Saharan Africa, though the World Health Organisation says it will have stamped out the disease in West Africa by 2002.

Color Blindness Although defective color vision may be acquired as a result of another eye disorder, the vast majority of color blind cases are hereditary - present at birth. Color blindness is rooted in the chromosomal differences between males and females. Females may be carriers of color blindness, but males are more commonly affected. About 8 percent of males and 0.5 percent of females are color deficient. Color blindness is a malfunction of the retina, which converts light energy into electircal energy that is then transmitted to the brain. This conversion is accomplished by two types of photoreceptor cells in the retina: rods and cones. The cones are responsible for encoding color. Each cone contains structures or visual pigments sensitive to one of three wavelengths of light: red, green, and blue. Normal persons are able to match all colors of the spectrum by mixtures of only three fundamental color sensitivities. Hence, the huge variety of colors we perceive stems from the cone cells' response to different compositions of wavelengths of light. Defects in color vision occur when one of the three cone cell color coding structures fails to function properly. One of the visual pigments may be present and functioning abnormally, or it may be absent altogether.

E - Mail Me The eye and a camera have a lot in common. They both have compound lenses. To focus a camera you move the lens backward or forward. The eye is focused by the ciliary muscle witch stretches the lens, changing its shape. The iris, just like the aperture in a camera, controls the amount of light that enters the eye. The aperture in a camera protects the film from over exposure. The iris in the eye protects the sensitive retina from light damage. The retina is like the film in a camera, covering the back of the eye. It contains millions of photoreceptor cells. These cells convert light rays into electrical signals that are sent to the brain through the optic nerve. The signals from both eyes are combined and converted into sight by the brain.

With this vision problem, you have difficulty distinguishing certain colors, such as red and green or blue and yellow. Red-green color deficiency is the most common form of color blindness; a less common form is blue-yellow color deficiency. Color Blindness Symptoms and Signs Do you have a hard time distinguishing if colors are red and green, or blue and yellow? This is the primary sign of this vision problem. Contrary to popular belief, it is rare that a color-blind person would see only in neutral colors or shades of gray. Eye doctors often use Ishihara plates to determine the severity and type of color deficiency. Someone with normal color perception can see the numeral among the dots. But someone with red-green deficiency would have trouble discerning the red among the green.

97. BLINDNESS By Jose Saramago blindness. I believe I lean much more to this notion that we are to understand blindness not as an allegory, but as an exploration of an alternative reality. http://www.webster.edu/~corbetre/personal/reading/saramago-blindness.html

BLINDNESS By Jose Saramago. Translated from the Portuguese by Giovanni Pontiero from the 1995 Ensaio sombre a Cegueira. 309 pages London: The Harvill Press, 1997 ISBN: 0-15-136700-9 Comments of Bob Corbett October 2001 Also appended remarks from George Snedeker December 2001 How are we to imagine a world in which some central part of our meaning system suddenly disappears? I've played with the idea in thinking about having survived an atomic war which destroyed most humans, and all the basic infrastructures of everyday life. The problems one runs into even in such a game of imagination is to be consistent and being able to step far enough away to see what it is that really changes. In my day-dreaming imaginings I never went so far as to even dare to consider the inner changes in my person or the other survivors around me. It was much more than I could do to even anticipate and manage the physical problems of change and how to deal with them. Jose Saramago presents us with exactly such a problematic, yet his masterful analysis deals not only with the physical aspects of change and how his characters deal with them, but he inters into the psychological realm and astounds us with his insights and brilliance. A man is sitting at a traffic light one day waiting for the light to turn green and he suddenly goes blind. This is the "first blind man." Slowly this mysterious form of blindness, the like not known in the literature of modern medicine, spreads to the whole nation. As best we know, there is only one sighted person left in the realm. We follow a cast of fewer than 10 characters in detail. We have no names, only descriptors. After all one character tells us "blind people need no names." There is the first blind man, the first blind man's wife. The blind man had a seeming good semaritan who helps him home and but then steals his car and is thus called the man who had stole the car. There is the doctor whom he consults and the doctor's wife, the girl with dark glasses, the boy with the squint and the man with the black eye patch. There are a few others, but these become our key characters, later on adding the dog of tears.

Home The Caucus Advisory Board Legislative Alert ... Related Links The Friends of the Congressional Glaucoma Caucus Foundation, Inc. (FCGCF) is dedicated to supporting the activities of the Congressional Glaucoma Caucus, a group of United States Congress members who are dedicated to helping all Americans fight the scourge of glaucoma and other eye diseases. FCGCF provides diagnostic screenings opportunities for high risk glaucoma population groups in their home districts across the nation. In support of the 77 members and former members of the Congressional Glaucoma Caucus, FCGCF arranges and provides screenings for glaucoma and other eye diseases throughout the United States at no cost to screening participants. From April 2001 to March 2004 we have screened approximately 23,500 individuals and have held over 640 screenings nationwide. Of those screened, approximately 34% were referred for further vision related medical treatment, and of those referred, 16% displayed signs consistent with glaucoma. It is well known that for the vast majority of individuals with glaucoma, the chances of preserving their sight is significantly improved if diagnosed and treated early enough. FCGCF targets groups of people at high risk of developing glaucoma or other eye disease, such as African Americans and Hispanics over the age of 40. We also target geographic areas, where adequate eye care is unavailable. FCGCF utilizes mobile facilities, complete with the most up-to-date screning equipment, so that we can travel to high risk areas.

Deaf-Blindness Information Web Page Webmaster Ed Keller Table of Contents: Introduction General Strategies Introduction People who are deaf-blind have problems of communication, mobility and other daily living skills that are unique and make independent living more dificult to achieve. It can be a dark, silent and isolating world. The term "deaf-blind" doesn't necessarily mean total lack of hearing and vision. Some people who are deaf-blind are partially "hearing and visually impaired." They may have enough hearing to understand speech, especially when using a hearing aid, and may have some usable vision with or without corrective lenses. "Legal blindness" is defined as the ability to see at a distance of 20 feet what a normally sighted person can see at 200 feet , or to have peripheral vision that is restricted to 20 degrees or less (like tunnel vision). However deaf-blindness does mean that the combination of impairments of both senses interferes with the ability of a person to function effectively in the "hearing-sighted" world.
