These 15 genes play different roles and have varying levels of influence on eye color. Eye color is almost impossible to predict and it doesn't entirely matter what color the parents' eyes are. Parents that have brown eyes could easily have a child with blue. and vice versa. The level of pigmentation (called melanin) is what determines the color. The less melanin, the lighter the color. Blue eyes have the least melanin in them, brown has the most. every other color is in-between.

Can a person be colored blind?

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 Blindness
English 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 Severity
The 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 Inheritance
One 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 Facts
Approximately 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 Test
There are several types of color blindness tests. The most commonly used color blindness tests are
- Pseudoisochromatic 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.

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.

Is a male narcissist more likely to have to an affair and blame it on the wife?
YES, YES and YES!!!! I was engaged to a narcissist for six months, after a four year relationship, and finally broke it off. My fiancee liked to compare me to my other girl friends (she's more interesting to talk to, she's more outgoing, etc). He even dated another woman at the beginning of our relationship and only told me two years later, to get it off his chest. He said I should get over it, and not feel hurt because he told me and it was so long ago. The first time he met one of my best friends, he asked her to go on a camping trip alone for a week. Embarrassed, she said to me, "hey, I think YOU'D like to do that". When I told him how much this hurt my feelings, he made me out to be a jealous girlfriend who did not trust him and said they'd be going as friends (he only met her once before). When I told him that this was inappropriate and that my friend felt embarrassed and I felt demeaned, he accused me of being jealous. Later, he would try to exaggerate my "jealousy" by making it a point to inform me of his whereabouts. Whenever he would call me "jealous", I would explain to him that I wanted him to have female friends, but that I felt like he should be able to tell me when they have plans. He treated me like I was paranoid and said he told me everything. When he got to the point of verbally abusing me for bing "paranoid and jealous", I made a last ditch effort to prove that I was not only sane but that he felt comfortably lying to me. I created a fake email account, and pretended to be a woman from his past that he admired, but whom he had lost touch with. Posing as this woman, I told him I was going to be in town for the holidays, and would like to get together. I made a point of picking a date that my fiancee and I had plans. My fiancee repsonded to the email with delight, mentioned he was engaged, but that it was at least a year away, and that he wanted to get together that night, but did not get the email in time. (he even lied to the fake person, and avoided telling her he was with me at a dinner party). He told her to call him at work, and not at home. When I showed him the email, he said it was sick of me to pose and someone else, blamed me for having to lie and even tried to make me understand why he would cheat on me. I felt worse because I had to resort to such tactics, and even after I made a valid point, he ignored my feelings, and offered reasons to cheat on me. He said that I was not mature enough to handle him having a relationship with other female friends, forgetting that I too had male relationships . He could not understand, that I was not jealous, and that I was not accusing him of being unfaithful, but that I felt disrespected, because he would be willing to make plans with other women in secret. He even went so far as to say that he lied to me for my protection. Narcissists cannot see past their own noses and have little interest in understanding how you feel. It's all about you understanding them. Thank you so much for your answer, I am actually the one that asked the question in the first place. I am convinced that I MUST get away from this man that I thought I loved for over 18 years. I would love to be able to talk to some of you in forum or chat room. Is it okay to leave my email address in a response or is there a forum of this nature? Please help, I'm realizing I need to get out and just don't know what to do. Thank you and Peace. Wow!! I married a N when I was 18- his first affair took place 2 wks before we were married. When he told me, we were in the car on a 6 hour trip, by the time the car ride was over I was convinced that it was my fault. He had a 3 year affair later in our marriage and lied lied lied, when I showed him the truth, again he blamed me and our son. We have been divorced for 10 years. He continues to this day to blame everyone around him for everything he does. As of late, he became abusive with our son and is blaming our SON!! Oh, and me of course. He can't keep his stories straight and is shaking in his boots because all of his secrets have been revealed. Truth scares Him and the less emotion I reveal the angrier he gets. He has gone as far as to accuse my sons therapist of being a pedifile!! Do You believe in Evil? I do!
