does being colorblind affect a person's lifespan???

I am colorblind and my opinion is that it does affect your lifestyle. especially when as a kid, in kindergarten and elementary school, where everything is color coded, or the teacher uses a tone of green in the blackboard. Many times teachers do not understand a student that has color deficiency. They label him as stupid or slow!!! A deficiency like that should be accepted, and there are many ways to help students with this problem and not making them feel guilty or worse offended. Of course it looks weird when a kid draws a picture of a green person or when he can't distinguish between the brown or red, or blue and purple. People like me do not understand words that other people name colors like. Some colors we can see of course, it's not like black and white; however, there are others that they are just the same color with a diferent name. IT DOES AFFECT A PERSON'S LIFESTYLE. Try matching your clothes, that gets a little bit harder being colorblind.

my uncle is completely colorblind. all he can see is black brown and white. he cant see very well because the colors blend together.

Here the woman is a carrier of both haemophilia and colorblindness, but she is normal.So her possibilities of children with the colorblind man will be a normal daughter, a colorblind daughter, a haemophiliac son and a color blind son. So the statment as i worked it out maybe correct and not wrong.

First of all, eye color can change with age. Second, it's more complicated that the simple brown / blue description that they give in high school biology class. So I suspect that the answer is yes.

sorry, I agree that D is correct. (\nhttp://www.abledata.com/abledata_docs/Night_Vision.htm )\n\nAs perception of white (or any gray levels) is the equal stimulation of all three different photopigments/photoreceptors, you can see all grey levels using your cones only. No mystery about it. If you understand additive color mixing you can use Photoshop to prove this on your computer. Or you can use colored transparencies and a projector. Research additive color mixing if you are not familar with it. So you can have no rods (look up night blindness) and still see black (no stimulation) and white (equal stimulation of all three cones) during the day time using your cones only. So the answer is no, you can not be "black, grey, white blind" , but it doesn't have to do anything with the presence or absence of rods in your eyes. \n\nThough there seems to be a really minor effect of rods on the perceived hue, colors could be somewhat less saturated,and it seems to rely on interaction of nerve cells other than the primary photoreceptor cell. Generally Pubmed or Google Scholar should both allow you to search large databases of science publications which haven't made it into textbooks.

Most color blindness is a sex-linked genetic condition. It is passed down mostly from mothers to sons, although some women can get it too.  \nIt can also be caused by damage to the function of structures needed for vision. \nThere are special filters and lenses a person can use to see better. \n\nHere is a link for more information.

we see color with rods not with cones. so missing rods will not affect your color vision.\nHumans have 3 different types of cone cells, red, blue and green. The difference between the 3 types is the pigment which absorbs the light. \nIf somebody is colorblind, it can be, because the cell is there, but not the pigment, or it can be that one cell type is entirely missing. \nAlso somebody can have all three visual pigments, but less of one type, so they are not as sensitive for that color than other people are. Look at this link how colorblind people see colors.

Good question, you can see for yourself here:\nhttp://www.vischeck.com/vischeck/\n\nor here:\nhttp://visibone.com/colorblind/\n\nor here:\nhttp://webexhibits.org/causesofcolor/2.html\n\nor many other places around the web with a little searching. Things get more muted with more greys and browns in the world.

Yes. My grandmother is blind from a disease known as maculuar degeneration.  She dreams in full color.  She doesn't know if the colors look like what everyone else sees, according to her.  But she dreams about an apple and it is what she thinks red should be.  She can "see" what an apple looks like by feeling its shape and texture.  She imagines the rest.

my own understanding to this is - and i might be wrong - it has an affect. i based this on Albinos, they lack pegimintation (melinen) in their skin and eyes (which gives them pink or red eye colour) and they have major eye-sight problems and sun can affect them alot. so i would assume the less pigement u have (i.e. blue) the greater affect u will have by sun (even if it is very little) but surely there is a difference.

You should probably talk to a Genetic Counselor.  I know SOME TYPES of colorblindness are sex linked traits (meaning the gene for the condition is on the X chromosome).  IF this is the case then it is more important to know if the mother is a carrier or not (because a red-green colorblind father will only pass on a Y chromosome to his son (not the affected X), and while the father will pass on the affected X to his daughter, since red-green colorblindness is a recessive disorder, the mother must also pass on an affected X to the daughter for the daughter to have the condition).\nThis is the case with SOME CASES of simple red-green colorblindness, but NOT for all types and cases of colorblindness. (Human disorders often deal with very complicated genetics...)\n\nYou should really seek the advice of a Genetic Counselor.  They will be able to explain the risks for you based on your family histories, as well as tell you for sure if there is prenatal or perynatal testing available, and will have better information than anyone on Yahoo answers can give you.\n\nI've provided a link that tells you all about Genetic counseling...what they do, where you can find one, etc...\n\n\nhope everything turns out ok

There IS no guarantee. In fact, it has been proven that people DON'T all see color exactly the same way. But it doesn't really matter, because there's no way to communicate how I see red to someone else, even if they see my perception of red as yellow.

Depends on the dream. If you are dreaming that you are falling, then color is not of great importance. And again it depends on if the person was born blind vs going blind at age 20 when this person knows what colors are.

Hi Maddy, I am taking a few moments this morning to reduce stress, pre-wedding jitters, not really nerves, just the usual worries of everything going correctly, as planned. lol \n\nSo, here I am anwering one of your great questions! ;-)  I too have often mused on how the blind or others who have lost a sense, manage to do things, normal everyday things those who have all five senses take for granted on a daily basis. I have mused on what it would be like to be blind. You see, one of my daughters had a knife put out her left eye when she was six. It was a horrific experiance for her and also her father and I. While she has not been completely blind sense birth, we have always been very worried, and sensitive of the worry she may lose sight in her one remaining eye. She was able to 'keep' her damaged eye, but she is basically 90% blind, only able to see shadows and blurred color in it. So, you can imagine this is something I have thought about a great deal. \n\nI read the answers you received when I first clicked here. Bonacua B is as close to an honest interpretation, or considered response than any other. Now, imagination does not require sight. They 'way' they imagine things will be different than those with sight, but they still will have dreams and imagination. Blind folks are as capable of those with sight of being able to be imaginative, innovative, creative and otherwise intuitive. They are in a unique position to provide an alternate view, which can be very impressive. When we are in a 'think tank' it is of best interest to implement as diverse a group as possible. When we keep the group diverse we are able to obtain a uniquely cohesive thought process which can produce great innovative and creative 'out of the box' thinking. This will enable the group to come up with a tremendously increased measure of ideas and concepts. When we place a group of non diverse members into a position of requiring innovative and creative ideas, they are limited to only simular processes as they all have the same abilities and therefor are limited. \n\nThe blind may not be able to see 'color' but color has more than a visual affect. Color is uniquely viewed by each individual with sight. Men and women see colors differently. There are scientific studies which demonstrate these differences between the sexes when it comes to seeing color. The blind are able to imagine colors by using verbal stimuli to create a visual concept. Colors also create emotions, blue is calming, red is stimulating, yellow is comforting, black can be either rage, or blankness, grey is dismal, etc. By utilizing all the elements of color the blind are able to concepulize these and form their own unique 'vision' of color. \n\nEmotions are very strong elements, and they are created from many differing sourses. When we are able to utilize all of our resourses we are then able to acheive our highest potentials. The blind are not any different in this as those who see. \n\nThose who are born blind do NOT increase other senses to 'compensate' for the lost sense. Studies have shown that the other senses which are seeminly increased, are available for the sighted to acheive those inhanced heighths. We ALL have the capasity to use our senses to a maximine capasite, the same as the blind, we just don't do it. When we are trained to use our senses to the highest levels we are able to acheive seeminly spiritual elements within our abilities to minipulate them. Most people just do not work on increasing their senses to the degree of their full capasity. The blind are trained to do so. So, it is not an ability to obtain any higher degree of use in remaining senses, above the ability of any seeing person, it is just they work at acheiving these 'high' degree of developed senses. \n\nI firmly believe the born blind are as able as any other to imagine and dream. The way this is manifested may be different, of course it

you need to have 20/20 vision and if you're saying you're colorblind - the chance for you getting into the law enforcement field is close to 1%.  And what do you mean by 'i can see colors fine' .. to me, it meant that you can see the colors and can distingish between colors and how is that make you a colorblind person?  i am confused ~

There is no treatment for color blindness.  It occures when there is a lack of certain color receptors in the eye. The person could be 'trained' to differentiate between the colors,\nbut would never be able to see true green or red.\n\nFYI- color blindness is a trait carried by the female but only shows up in males.
