In this blog you will find out what a color vision disorder is, what forms of color blindness there are and what their biological causes are. <\/span>We also show which symptoms can be used to recognize a colour vision disorder, which challenges it poses in everyday life and which aids and tips are available for those affected! <\/span><\/span><\/p>\n

What is color vision deficiency<\/span><\/span><\/h2>\n

Color vision deficiency is a disorder that is more commonly known in our language area as color blindness. <\/span>This is an impairment of color vision. <\/span>People who suffer from color blindness have difficulty recognizing and distinguishing certain colors correctly. <\/span>In short, this is because the photoreceptors in the eye, which are responsible for color recognition, do not function properly. <\/span><\/span><\/p>\n

Causes in the eye for color vision disorders<\/span><\/span><\/h2>\n

If color perception is disturbed, this can have various causes. <\/span>However, the reason is always similar on a biological level: the photoreceptors in the retina are malfunctioning. <\/span>These are specialized cells that are responsible for converting light stimuli into electrical signals, which can then be transmitted to the brain via the optic nerve. <\/span>A distinction is made between:<\/span><\/span><\/p>\n

    \n
  1. Chopsticks <\/span><\/span><\/li>\n
  2. Cone cells <\/span><\/span><\/li>\n<\/ol>\n

    The cones are responsible for color perception and are divided into three types that react to different wavelengths of light: <\/span><\/span><\/p>\n

      \n
    • M-pin for the color green <\/span><\/span><\/li>\n
    • L-pin for the color red <\/span><\/span><\/li>\n
    • S-pin for the color blue <\/span><\/span><\/li>\n<\/ul>\n

      The remaining colors are created by mixing green, red and blue. <\/span>In most cases, the M and\/or L cones are affected, leading to the well-known red-green weakness. <\/span>In exceptional cases, however, all types of cones are affected, so that those affected are completely colorblind. <\/span><\/span><\/p>\n

      Types of color vision deficiency<\/span><\/span><\/h2>\n

      Color blindness occurs in different forms. <\/span>While some people are hardly affected at all, there are others who have major problems with their color vision impairment in everyday life. <\/span>By far the most common form is “red-green vision loss”. <\/span><\/span><\/p>\n

      As the name suggests, these people find it extremely difficult to distinguish between the shades of red and green. <\/span>And this is not only problematic when driving at traffic lights. <\/span><\/span><\/p>\n

      What other color blindnesses are there? <\/span>Causes i objaw <\/span><\/span><\/h3>\n
        \n
      • Protanomaly (red-weak): The color red is perceived incorrectly. <\/span><\/span><\/li>\n
      • Protanopia (\u015blepa na zgnilizn\u0119): The color red cannot be seen at all. <\/span><\/span><\/li>\n
      • Deuteranomaly (weak green): Green color tones can be perceived to a limited extent. <\/span><\/span><\/li>\n
      • Deuteranopia (green-blind): Green is invisible. <\/span><\/span><\/li>\n
      • Tritanomaly (blue-weak or yellow-green-weak): Blue and yellow color tones are disturbed from perception. <\/span><\/span><\/li>\n
      • Achromasia (total color blindness): Seeing the world in black, white and shades of gray. <\/span>No color perception in the true sense of the word. <\/span><\/span><\/li>\n<\/ul>\n

        Congenital and acquired color vision deficiency or color blindness <\/span><\/span><\/h2>\n

        Either you’ve always had it or it develops as you get older. <\/span>For this reason, a distinction is made in medicine between congenital and later acquired color vision disorders: <\/span><\/span><\/p>\n

        Congenital color vision disorders: Make the diagnosis early<\/span><\/span><\/h3>\n

        If the color vision disorder is congenital, wi\u0119c you have always had it. <\/span>It often first appears in early childhood during the phase in which the eye learns to recognize colors. <\/span>Parents or educators often notice quickly if the child has difficulty recognizing and naming colors. <\/span>Then it is high time to have this checked by an ophthalmologist. <\/span>The confusion between red and green is particularly common. <\/span>There, the disease can be diagnosed with color charts and other examinations of the retina of the eye. <\/span><\/span><\/p>\n

        Men are significantly more frequently affected by a congenital color vision disorder than women. <\/span>About 8 percent of men and only 0.5 percent of women in Europe suffer from one of the above-mentioned forms of color blindness. <\/span>The overrepresentation of men is probably due to the prevalence of defective color vision genes on the X chromosome. <\/span>Color vision disorders can be inherited.<\/span><\/span><\/p>\n

        Acquired color vision disorders: A case for the ophthalmologist <\/span><\/span><\/h3>\n

        If the color vision disorder occurs later in life or <\/span>In adulthood, it usually comes on suddenly and is accompanied by certain health problems. <\/span>One example of this is the <\/span><\/span>age-related macular degeneration (AMD for short) <\/span><\/span>in which the retina changes in such a way that color vision can also be affected. <\/span>However, diabetes and certain medications can also contribute to color blindness. <\/span><\/span>In principle, color blindness can develop at any time. <\/span>Statistically, however, older people are more frequently affected, as they also suffer from eye diseases more often. <\/span>Regardless of the intensity and cause, a sudden onset of color blindness should be clarified as soon as possible. <\/span>After clarification, the ophthalmologist can make a diagnosis and treat the color blindness if necessary. <\/span>treat the color vision defect if necessary. <\/span><\/span> <\/p>\n

        How color vision disorders affect daily life<\/span><\/span><\/h2>\n

        Even if people with color blindness or <\/span>Although people with color vision deficiency adapt to circumstances over the course of their lives, there are always situations in which the impairment affects their lives. <\/span>For example in the following areas: <\/span><\/span><\/p>\n

          \n
        • Everyday life: reading traffic lights correctly, recognizing color markings and choosing clothes in matching colors. <\/span><\/span><\/li>\n
        • Education: In school or at work, problems can arise with certain tasks because, for example, diagrams cannot be recognized correctly. <\/span><\/span><\/li>\n
        • Occupation: Particularly in occupations where color recognition is important, those affected have difficulties. <\/span>For example in the fields of graphic design, art, transportation and logistics. <\/span><\/span><\/li>\n
        • Social interaction: Recognizing and interpreting facial expressions can also be difficult. <\/span>But a visit to the museum is also experienced differently. <\/span><\/span><\/li>\n
        • Art and \u0118sthetics: people with color vision disorders experience art completely differently. <\/span>Their experience also differs when watching movies or looking at pictures.<\/span><\/span><\/li>\n<\/ul>\n

          How strong the effect is always depends on which color vision disorder is present and how pronounced it is. <\/span>In most cases, however, those affected can lead a largely normal and fulfilling life – even with complete color blindness. <\/span><\/span><\/p>\n

          Aids and support for color vision deficiency<\/span><\/span><\/h3>\n

          There are now various approaches to making life as barrier-free as possible. <\/span>Color filter glasses are special glasses that are developed to compensate for color vision disorders and thus improve the differentiation of colors. <\/span>Ideally, they are individually adapted to the eye. <\/span><\/span><\/p>\n

          But modern apps and online tools can also help people with color vision deficiency. <\/span>These are able to identify and display colors in texts, images and videos. <\/span>This also includes special software that adjusts the screen on cell phones and computers so that the colors are displayed optimally. <\/span><\/span><\/p>\n

          Well-designed lighting of rooms and objects can also enhance the color contrasts and thus facilitate recognition. <\/span>Especially in public spaces, the sensitivity for people with color vision deficiencies has increased significantly and elements that are universally legible and recognizable are implemented accordingly in the design. <\/span><\/span><\/p>\n

          Treating color blindness: Can a color vision disorder be cured?<\/span><\/span><\/h2>\n

          There is still no complete cure for congenital color vision disorders in particular. <\/span>This is because it is based on a genetic defect that cannot be compensated for. <\/span>However, for these people there are the aforementioned options to alleviate the symptoms of color blindness. <\/span><\/span><\/p>\n

          If color blindness or <\/span>If a color vision disorder only becomes apparent later, it often helps to treat the cause. <\/span>For example, if AMD is cured, color perception can recover.<\/span><\/span><\/p>\n

          In any case, it is worthwhile for those affected to seek the expert advice and examination of an ophthalmologist. <\/span>They know the right tools, have the perfect treatment method if required and can help you to live your best life – even without red, green or blue.<\/span><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
