What do people see when they have color blindness?
The same but imagine changing certain colours.
Which term indicate the inability to distinguish between colors such as red and green?
its color defiency :) color blindness is when u cant see any colors and it is very rare.
Are there glasses or contacts for color blindness?
I do not believe color blindness is correctable with any type of lens. It is caused by the absence/malfunction of the proper structure (cones) within the eye to detect certain wavelengths of light and thus, certain colors. Red lenses will help with the test for color blindness.
Normal life expectancy of color blind?
Color blindness typically does not affect life expectancy. It is a hereditary condition that primarily impacts the way individuals perceive colors. People with color blindness can lead normal, healthy lives without any impact on their overall life expectancy.
Can a person be colored blind?
Yes,Color blindness is a color vision deficiency, characterized by a persons inability to differentiate between various colors. Although color blindness is genetic in nature, i.e. passing from one generation to another, a substantial amount of cases are related to damage caused to eye, brain or nerves. Though rare, exposure to certain chemicals can also trigger color blindness. Although color blindness is technically a wrong term to refer to this eye problem, it is preferred over color vision deficiency, owing to the simplicity of pronunciation as well as understanding for a lay man. Although it's a minor disability, there are certain situations wherein being color blind can cause difficulties for the individual in various walks of life. Simple things like choosing clothes or reading analytical diagrams may seem like a tedious task for a color blind individual. Let's have a detailed look at some of the prominent color blindness facts.Facts About Color BlindnessEnglish scientist John Dalton was the first person to present a paper on color blindness and as a mark of respect for his contribution, color blindness is also referred to as Daltonism. Interestingly, John Dalton was a color blind himself. Some simple yet interesting color blindness facts are mentioned below.Color Blindness SeverityThe severity of color blindness is usually categorized into four parts.Slightly color blind.Moderately color blind.Strongly color blind.Absolutely color blind.Scientifically, absolute color blindness or complete color blindness is referred to as achromatopsia or monochromacy. Complete color blindness is most often associated with eye conditions such as amblyopia and nystagmus.Color Blindness InheritanceOne of the most interesting facts about color blindness is about inheritance of the disorder. Color blindness is one of the genetic disorders in humans. As the most common form of this deficiency is related to X chromosome or color blindness chromosome, color blindness tends to be more common in males than in females. But color blindness genetics also suggest that even though women are not color blind themselves, they are very active carriers of color blindness. Interestingly, a mother is bound to pass her red-green color blindness to all her sons, but its less likely for the father to do the same.Red Green Color Blindness FactsApproximately 99 percent of all color blind people suffer from red-green color blindness. Statistics reveal that around 75 percent of people suffering from red-green color blindness have problems with green perception, while the remaining 24 percent have problem with red perception. But this doesn't mean that a person suffering from red-green color blindness tends to mix up between red and green colors only. The fact is that the problem prevails in the whole color spectrum. The most common form of color blindness is deuteranomaly, a form of red-green color blindness. Red-green color blindness is a recessive sex linked, and therefore we see that more men are color blind than their female counter parts.Color Blindness TestThere are several types of color blindness tests. The most commonly used color blindness tests arePseudoisochromatic plates.Arrangement test.Anomaloscope test.Among the various tests for color blindness, anomaloscope, which measures the quantitative and qualitative anomalies in color perception, gives the most accurate color blindness results. Ishihara plates are also popularly used for testing color blindness, but they are comparatively less accurate. Color blindness deficiency can be corrected to a certain extent by wearing color correcting lenses. A person wearing these correcting lenses wears two different colored lenses in his/her eyes. Read more on, tests for color blindness.These were some of the common color blindness facts, which everyone ought to know. Although color blindness is classified as a disability, one of the most interesting facts about color blindness is the advantage that the color blind people tend to have over people with normal vision. One such advantage is the ability of color blind people to penetrate certain camouflages with ease. As of today, there is no accepted treatment of color blindness, but there is a hope that we will have one very soon.Source view related links.
Is there any research currently being conducted on color blindness?
There will never be a cure or treatment
What age do you die from color blindness?
You can become color blind at any age.
Do color blind people live to the normal life expectancy?
Color blindness does not effect the aging process at all. It won't cause hardly any complications throughout life, except that we often confuse colors.
Can accutane cause color blindness?
It's unlikely that Accutane will cause any sort of color blindness, however there are a number of other side effects of Accutane including Crohn's disease, Irritable Bowel Syndrome, Depression, Ulcerative colitis, and others.
Who is at risk of color blindness?
In a sense no one is at risk at all for color blindness; it is a genetic condition that you either have or do not have. It is not an illness against which you must protect yourself, or that poses a non-zero risk to people who are not color blind. Men are more likely to be color blind, because it is a recessive gene on the X chromosome, with no corresponding gene on the Y chromosome to keep it from appearing. Women can be color blind, but only if the father is color blind and the mother is either color blind or a carrier of the recessive gene on one of her X chromosomes. My brother happens to be red-green color blind, and I have normal color perception. This indicates that our mother is a carrier; one of her X chromosomes has the recessive gene and the other does not. Our father also had normal color perception, but regarding my brother and me, this is irrelevant; we got his Y chromosome, not his X.Color blindness does not involve an actual form of blindness, or an inability to perceive light. There are some physical conditions that may lead to different kinds of actual blindness in the eye, and some of these conditions also impare color perceptions. Technically, these are forms of blindness and not color blindness as we generally use the term.It is a fallacy that all color blind people see everything in black, white and shades of gray. It appears that only a small percentage of people dealing with color blindness have this condition. It is a fallacy that red-green color blind people see red and green objects as gray. The truth is that people who have any form of color deficiency will have some difficulty identifying or matching a great many colors, and not just the colors that are misleadingly attached to the form of deficiency that they have. This is so because very few colors in our everyday world are completely pure. There are infinitely many mixes and combinations of colors in the objects that we see throughout the day. A person with a red and/or green perception problem will have some difficulty perceiving colors that have any mixes of red and/or green in them.

What are the colors that color blind can see?
There are a couple of different kinds of color blindness. The condition usually happens because of a defect in the mechanism that makes one or more of the pigments in the eye that allow the eye to respond differently to different wavelengths of light.The two most common types are "red-green" color blindness (the most common; such people have trouble distinguishing between red, orange, yellow, and green) and "blue-yellow" color blindness (people who have trouble distinguishing between blue and green and between red and yellow). Depending on the exact genetic defect involved, this can range from a complete inability to distinguish between the colors, or varying degrees of difficulty in doing so.Much rarer is true color blindness, where the person cannot see any colors at all and everything appears as shades of gray.
