• #1 Color Blindness: Types, Causes & Treatment

  https://my.clevelandclinic.org/health/diseases/11604-color-blindness

  Color blindness is when you dont see colors in the traditional way because some cones (nerve cells) in your eyes are missing or dont work correctly. If you or your child has color blindness, its important to learn the type and severity. Talk to an eye care provider (optometrist or ophthalmologist) about the nature of the condition and how it may affect you. Color blindness can be either inherited (youre born with it) or acquired (you develop it later in life). The causes are different in each case. Currently, theres no medical treatment or cure for people with inherited color blindness. If you have acquired color blindness, your healthcare provider will treat the underlying condition or adjust your medications as needed. This may help improve your color vision. If your child has color blindness, talk to their eye care provider about adjustments that may help them in school. Its also important to talk to your childs teachers about your childs condition and how best to support their learning.

  Color vision deficiency is the inability to distinguish certain shades of color. The term „color blindness” is also used to describe this visual condition, but very few people are completely color blind. […] Most people with color vision deficiency can see colors. The most common form of color deficiency is red-green. This does not mean that people with this deficiency cannot see these colors altogether, they simply have a harder time differentiating between them, which can depend on the darkness or lightness of the colors. […] People who are totally color deficient, a condition called achromatopsia, can only see things as black and white or in shades of gray. Color vision deficiency can range from mild to severe, depending on the cause. […] A person could have poor color vision and not know it. Quite often, people with red-green deficiency aren’t aware of their problem because they’ve learned to see the „right” color.

  If you have colour vision deficiency (also called „colour blindness”), you are unable to see certain colours. The most common form of the condition is red-green colour vision deficiency. Colour vision deficiency is usually first diagnosed using special coloured pictures called Ishihara plates. […] The effects of colour vision deficiency can be variable – from mild to severe. Some people with colour vision deficiency don’t even know they’ve got it. Others may have a lot of difficulty and be unable to work in certain jobs. […] Colour vision deficiency means you are unable to see certain colours. There are different types of colour vision deficiency. For example, you may be unable to tell red from green or blue from yellow. Red-green colour blindness is by far the most common form. […] Colour vision deficiency is usually first diagnosed using special coloured pictures called Ishihara plates. The Ishihara plate has 16 different diagrams made up of dots to show a number.

  https://patient.info/eye-care/colour-vision-deficiency-colour-blindness

  There is no treatment that can correct or prevent inherited (genetic) colour vision deficiencies. […] Colour blindness affects about 1 in 12 men and 1 in 200 women. It is much more common in men because the most common form (red-green colour vision deficiency) is passed on in a gene on the X chromosome. […] Nearly all people with colour blindness can see things as clearly as other people but they cannot see certain colours clearly. If you have red-green colour vision deficiency you will not be able to clearly see any colour which has some red or green as part of the whole colour. […] Colour vision deficiency may cause difficulty at school. Colour vision deficiency can also affect the choice of certain jobs and careers. The list of careers that may not be possible for a person with colour vision deficiency includes: Certain grades within the armed forces, Civil aviation: pilots, engineers, technical and maintenance staff, air traffic controllers, Customs and excise officers, Railways: drivers, engineers and maintenance staff, Fire service officers, Hospital laboratory technicians and pharmacists, Workers in paint, paper and textile manufacture, photography and fine art reproduction. […] However, the restrictions vary. For example, Australian airlines do now allow people with colour vision deficiency to be pilots.

  Congenital colour vision deficiency (CVD) has a prevalence of 8% for men and 0.4% for women. […] Most CVD persons have difficulties dealing with colours in everyday life and at work, but these problems are under-reported due to a lack of its awareness in the general population. […] CVD affects many aspects of life from childhood to adulthood. The implications extend across play, sports, driving, education, occupation, discrimination, and health and safety issues. Awareness of CVD helps to identify and develop corresponding coping strategies. […] More work needs to be done in raising awareness of CVD and its implications, as well as implementing measures to overcome these difficulties. […] All people with CVD, except for a few mildly affected deuteranomals, report that they encounter problems with colour perception in everyday life and at work.

• #6 Why Men Are More Likely To Be Colorblind | Henry Ford Health – Detroit, MI

  https://www.henryford.com/blog/2024/10/why-men-are-more-likely-to-be-colorblind

  Most cases of CVD are caused by a genetic mutation that affects the cone cells in the eye. The gene that causes CVD is on the X chromosome, and it’s a recessive trait. […] Recessive traits typically mean you must inherit the genetic mutation from both parents to have the condition. But here’s why males get CVD more: Females have two X chromosomes (XX), but males only have one (XY). […] Males only have one X chromosome, so they can’t override the gene variant. Males can get the CVD gene variant from just one parent, says Dr. Sethi. […] Most people with CVD have the inherited type, so they’ve had it since birth. But a different kind of CVD, known as acquired CVD, isn’t caused by genetics and affects people later in life. […] Inherited CVD isn’t a health problem—it’s just a variation of normal vision. You can live a full, healthy life with genetic color vision deficiency, says Dr. Sethi. Most people adapt very well to seeing the world differently.

  Color blindness is when you are unable to see colors in a normal way. It is also known as color deficiency. Color blindness often happens when someone cannot distinguish between certain colors. This usually happens between greens and reds, and occasionally blues. […] Color blindness can happen when one or more of the color cone cells are absent, not working, or detect a different color than normal. Severe color blindness occurs when all three cone cells are absent. Mild color blindness happens when all three cone cells are present but one cone cell does not work right. It detects a different color than normal. […] Color blindness is usually something that you have from birth but you can also get it later in life. Change in color vision can signify a more serious condition. Anyone who experiences a significant change in color perception should see an ophthalmologist.

  Those with tritanopia struggle to distinguish between blue and yellow hues, primarily due to a deficiency in blue cones. […] Monochromacy is the most severe form of color blindness, where individuals see the world in shades of gray. […] Individuals with this type have no cone function and can only perceive light and dark, making it very challenging to differentiate objects based solely on color. […] In this case, individuals possess one type of cone (either red, green, or blue) but lack the others. […] This is a milder form of color blindness where individuals have three types of cones, but one type is altered, resulting in color perception deficiencies. […] The majority of color blindness cases are inherited through genetic transmission. […] If a male inherits an X chromosome with the gene for red-green color blindness, he will express the condition because he lacks a second X chromosome that could provide a normal copy of the gene.

• #23 Awareness of colour blindness among nurses

  https://ijrps.com/index.php/home/article/download/2265/8648?inline=1

  The primary aim of this study is to find the awareness of colour blindness among 100 nurses in a hospital. Colour blindness or colour vision deficiency is the decreased ability to see and distinguish colours. There is no cure for colour vision deficiency. The result was that the nurses knew what colour blindness is, but they did not know much about the aetiology, transmission, treatment of the disorder. The nurses should be made more aware of colour blindness. Awareness of this disorder is fundamental to guide these patients to choose their career, especially among medical personnel. In this study conducted among 100 nurses, 70% have heard of the term colour blindness, and 63% knows what colour blindness is. Unilateral colour blindness is a rare condition wherein one eye is colour blind, other is normal. About 40% of nurses who took part in this study are aware of it. In this study, when asked about the most common cause of colour blindness, 69% answered it right as genetic. Colour vision deficiency can also be acquired due to the use of certain drugs like sildenafil, digoxin, ethambutol. Colour-blind individuals cannot be allowed to drive vehicles as the perception of traffic signals, and warning signs are difficult for them. These people are also not allowed to become pilots, nurses, doctors, electricians, engineers, i.e., wherever the perception of colours is essential. Congenital colour blindness cannot be cured entirely, and this was known by 55 % of nurses. It can be concluded that the nurses are not fully aware of colour blindness. Most of them know what colour blindness is and the most common aetiology of it. But they are not aware of the mechanism, challenges that it causes in daily life, the occupations which they cannot be employed in, diagnostic method and treatment. So more efforts should be taken, and nurses should be taught well about this disorder and how a colour blind person should be dealt with.

• #36 The Importance of Understanding Color Vision Deficiency

  https://www.2020mag.com/article/the-importance-of-understanding-color-vision-deficiency

  The Importance of Understanding Color Vision Deficiency […] Color deficiency education is so important because people often overlook how much the inability to see certain colors can change a persons life. It affects everything from what jobs a color deficient person can do to small choices like what that person would want to eat. Since color deficiency does not physically hurt the patient, those without color deficiency do not realize the patient is being forced to adapt to a world in which he or she cannot properly perceive a significant portion. By educating people both with and without color deficiency of the effects of cone pigment problems, the gap between both perceptions can be significantly lessened. […] Children with any form of color deficiency also have a huge disadvantage early on in life. Most teachers do not realize how prominent colors are in education. In fact, a poll done by researchers from the British Journal of School Nursing found that 26.3% of the surveyed teachers did not realize color affects a students ability to learn. This is because teachers are unaware of why such an issue could hurt the child. The reason color deficient students struggle, especially early on, is because the student may be unable to understand material given in class. Examples can include worksheets, books, and supplies like crayons. All these items are staples of a school environment, which is why they go, unnoticed. As a result, the child fears he or she is not as smart as the rest of the class and loses the motivation to want to learn. This is most apparent in earlier ages because color education has a higher relevance. In recent years in the UK, there has been a bigger push to help those with any form of color deficiency. Instances include labeling specific colored items and instructing teachers to look for warning signs of color deficiency. While these adjustments may seem small, they are crucial in allowing a color deficient child to flourish since it gives the child access to the same resources as any other child.

  There is no treatment that can correct or prevent inherited (genetic) colour vision deficiencies. […] Colour blindness affects about 1 in 12 men and 1 in 200 women. It is much more common in men because the most common form (red-green colour vision deficiency) is passed on in a gene on the X chromosome. […] Nearly all people with colour blindness can see things as clearly as other people but they cannot see certain colours clearly. If you have red-green colour vision deficiency you will not be able to clearly see any colour which has some red or green as part of the whole colour. […] Colour vision deficiency may cause difficulty at school. Colour vision deficiency can also affect the choice of certain jobs and careers. The list of careers that may not be possible for a person with colour vision deficiency includes: Certain grades within the armed forces, Civil aviation: pilots, engineers, technical and maintenance staff, air traffic controllers, Customs and excise officers, Railways: drivers, engineers and maintenance staff, Fire service officers, Hospital laboratory technicians and pharmacists, Workers in paint, paper and textile manufacture, photography and fine art reproduction.

  The primary aim of this study is to find the awareness of colour blindness among 100 nurses in a hospital. Colour blindness or colour vision deficiency is the decreased ability to see and distinguish colours. There is no cure for colour vision deficiency. The result was that the nurses knew what colour blindness is, but they did not know much about the aetiology, transmission, treatment of the disorder. The nurses should be made more aware of colour blindness. Awareness of this disorder is fundamental to guide these patients to choose their career, especially among medical personnel. In this study conducted among 100 nurses, 70% have heard of the term colour blindness, and 63% knows what colour blindness is. Unilateral colour blindness is a rare condition wherein one eye is colour blind, other is normal. About 40% of nurses who took part in this study are aware of it. In this study, when asked about the most common cause of colour blindness, 69% answered it right as genetic. Colour vision deficiency can also be acquired due to the use of certain drugs like sildenafil, digoxin, ethambutol. Colour-blind individuals cannot be allowed to drive vehicles as the perception of traffic signals, and warning signs are difficult for them.
