Color Blindness means that you have trouble seeing the colors green, blue, or red or a mix of these

A medical definition of vision impairment is a sine qua non that prohibits 20/20 vision in one or both eyes (Bowman, Bowman, Dutton & Royal National Institute for the Blind, 2001; Vision Australia, 2015; Webster & Roe, 1998). Examples of vision impairment include, cataracts, which has the lens inside the eye increasingly cloudy; albinism, which is passed down genetically affecting clear vision and causes sensitivity to bright light; optic nerve damage, which affects field of vision as those nerves controlling vision are disrupted; macular degeneration, where parts of the retina that control colour and fine details are affected; retinitis pigmentosa, which is an ongoing reduction of the field of vision available and nystagmus, where the eye flickers involuntary (Bowman, Bowman, Dutton & Royal National Institute for the Blind, 2001; American Foundation for the Blind, 2015; Vision Australia, 2015 ; Baton Rouge Regional Eye Bank, 2015). John suffers from retinitis

How eyes see color is pretty simple, our retinas approximately six million cone cells. Each cell in the retina is assigned to a certain color. There are three different types of cone cells, blue, green, and red, which correspond to the three primary colors. Being colorblind is more likely to happen to boys than to girls. By reading the article after the colorblind test I also learned that people who suffer from being color blind are not blind to a color, but have trouble seeing a certain shade of a color. Another, thing that I learned is that being colorblind can be inherited genetically or if you damage one of genes “photopigments” you also can become color blind. If I had never read this article, I would have never learned all this interesting and great knowledge to

When I hear the term colorblind it makes me think we are supposed to ignore part of the human. It's like they're trying to tell us that race no longer “matters” in American society. I personally hate this term, if you ignore something and act as if a problem doesn't exist. It just gets bigger and bigger and doesn't go away. Then negative feeling or the issues become worse or more intense, especially through long-term neglect or indifference. It's just like anything in life if you ignore something by the time you go back to it, the problems harder to clean up.

Retinitis pigmentosa is a group of inheritable diseases that is characterized by gradual deterioration of the photoreceptors in the retina. The photoreceptor cells in the retina, rod cells, are light sensitive cells that are able to sense low levels of light. The frequency of retinitis pigmentosa is one in four thousand births (Deng et al., 2015; Fahim et al., 2012; Haddad et al., 2016; Shu et al., 2012) People affected by retinitis pigmentosa will typically exhibit symptoms of night-blindness first, and this will precede a loss in the patient’s visual acuity field that starts from the outer edge and gradually moves inward resulting in a much smaller visual field and loss of peripheral vision, also known as tunnel vision (Haddad et al., 2016).

Since its sex-linked, then you know the father has normal vision, then he has a dominant allele on his X chromosome. Since the color blind child in question is a son, then he inherited a Y from the father. So, the colorblindness

The term colorblind is most commonly known as a visual disability. This is not how I am defining the word colorblind. Love knows no color. Some people that are my “family” look a lot different than me. For instance, I am a Caucasian female, but Michael, who is like a brother to me is an African American male. Michael has been there for me as a friend and mentor for a long time. His role in my life has been more like a brother than my legal brother who shares my last name. People don’t always see eye to eye when it comes to race and relationships, but it family isn’t coated in all the same skin. People’s ignorance to this topic prevents them from enjoying all that some people have to offer. I for one like to be well rounded and cultured. Having a wide variety of people that I call family has made me who I am today; the good, the bad, the ugly, yet I am thankful for it

Albinism is a group of disorders that occur when a person inherits various genes that cannot produce the pigment melanin, which is the main substance that gives a person’s skin, hair, and eye color. The disease is divided into two types, oculocutaneous albinism, OCA, and Ocular Albinism. OCA causes decreased pigment in the eyes, hair, and skin. There are 4 types of OCA that are differentiated depending on the type of genetic defect. Ocular albinism affects primarily the eyes, while the skin and hair show normal or near-normal coloration.

“Achromatopsia affects roughly 1 in 33,000 Americans.” (2) Achromatopsia is a condition in which a person loses partial or all of their ability to see color and can also be referred to as achromatism, rod monochromatism, or total color blindness. It is the result of a change in one of the following genes: CNGA3, CNGB3, GNAT2, PDE6C, or PDE6H. Achromatopsia is a disorder that affects the retina, which is the part of the eye that is sensitive to light and forms visual images. Inside the retina is two different types of light receptor cells, called rods and cones. These cells use a process called phototransduction to send visual signals from the eye to the brain. Mutations in any of the genes above disrupt the phototransduction process, affecting

Well, that is not true, there are a minimum of three sets of genes that control eye color and what’s more is that even if you have the dominate alleles for brown eye color, they can get shut off through other things. Things that happen during development in the womb and things that happen in the environment after you are born can turn those off. You can end up with blue eyes even though you have the genes for brown eyes and then they can pop up in the next generation, so blue eyed parents can have a brown eyed kid without and hanky

How is being colorblind a disadvantage? Being colorblind can take away from certain experiences. Such as driving down the road and looking at the trees. Most colorblind people will see darker red and green colors as a dark orange or yellow. It can also make people have trouble determining if there meat is properly cooked, and if their fruits have ripened. This may not seem like a big deal, but it could still have a bad effect on them. Another example at night it is nearly impossible to see

John Dalton has been known to have discovered his own colour blindness in the year of 1794, seeing pink as blue and scarlet as green. The vitreous humor is known as a gel that can fill a space that is in-between the lens and retina of the eyeball, it’s also known as vitreous body. There are around 1 in 12 man and 1 out of 200 women that colour blindness affects in their everyday life, there are also different types of colour blindness that affects many such as Deuteranomaly or Protanomaly are also known as red-green where they find it difficult to see reds, greens, browns and oranges (Colour Blindness Awareness, Accessed 17.08.2015). Monochromatic which is seeing no colour at all. In a person’s eye there are three colours that make up all

Red-green colorblindness is usually hereditary as it is passed down from an individual’s parents. Chemicals that get into contact with the human eyes can also cause the disorder.

     There are two types of Macular Degeneration. Juvenile Macular Degeneration affects the central vision in young children. This takes place in the macula, or the central region of the retina. The retina is where we are able to read and to distinguish colors. The main symptoms

As stated earlier men have a much greater chance of having color vision deficiency. (WC #6) From data gathered of populations in Northern European ancestry, 1 in every 12 males has red-green colorblindness compared to 1 in every 200 females. (WC #4) Therefore, poor color vision is primarily genetically inherited for the most common forms. (WC #6) Red-green color blindness is an X-linked inheritance that is carried by the mother. For women, since there are two X chromosomes, normally the normal gene can offset the mutated X chromosome. (WC #3) When that happens the women does not have the disease; however she is still a carrier of the gene to her offspring. If
