Color vision

Theories of Color Vision The visual abilities of human beings are incredibly fascinating. We can view a large range of color from a small choice of wavelengths along the electromagnetic spectrum, 400nm-700nm. Our understanding of this perception of color comes from two major theories Tri-chromatic theory of color vision and opponent-process theory. Both theories have their merits and one actually grew out of the other. The first theory proposed was the tri-chromatic theory. The tri-chromatic theory of color vision states that our color vision is dependent on activity of our three color receptors. It goes on to say that the mixture of these three independent wavelengths for color could produce any other given color on the visual spectrum.…

overcoming color vision deficiency. This sections gives the main challenges in making a user interface for colorblind users are: 1. Frequency of calibration All the models of color differentiation depends on an in-situ calibration. Moreover, this calibration is short [] and whenever the environment is changes user are not able to perform new calibration. These can be overcome by storing the calibration for future use and expanding the applicability of a calibration. By storing the calibration,…

The Army doctrine is working on the Expert Action Badge (EAB); we should notice it by October 2019 if approved. The EAB plans to allow Soldiers to make professional goals in line with their Military Occupational Specialty (MOS). An example would be the Infantry has the Expert Infantryman Badge (EIB) and the Medical Corps have an Expert Medical Field Badge (EFMB). The Expert Action Badge is not similar to the Expert Infantryman Badge, which focuses solely on for infantry related skills. The…

Characteristics of Vision in Children with CVI The visual system is a powerful and complex tool for understanding and perceiving the world. It has many aspects and dimensions that change throughout an individual’s lifetime. Therefore, it is unsurprising that there are many stages of vision at which perception can become impaired. Cortical (or cerebral) visual impairment (CVI) refers to any impairment or loss of vision brought about by damage to the brain or the central nervous system, rather…

(Swartout-Corbeil, n.d.). Newborn infants can only see black, white, and shades of gray, so, their perception of the world is a sort of jumble with the novelties of new life. At around four months old, human infants can see the full range of the colors. The myth that babies…

Chicken Run (2000) was also a reminded of never losing sight of your visions and goals. After several planned attempts of trying to escape Tweedy’s Egg Farm, Ginger the main character, is placed in solitary confinement for trying to escape her semi-organized group to freedom. Even though all the chickens want to escape, Ginger is the one most passionate about the cause. She believes there is more over the gate and has visions that every chicken deserves have the right to be free. The story…

readers by stating that one of the three colors that the human eye is sensitive to is the color yellow. However, according to Lilienfeld et al. (2014), the Trichromatic theory actually suggest that the human eye contains specific photoreceptor cells, specifically cones, that are responsible for colored vision and are sensitive to the colors red, green, and blue. Also, the paper incorrectly defines the location of the rods and cones within the eye by stating that these photoreceptor cells…

The author of Fight Club, Chuck Palahniuk, once stated, “The trick to forgetting the big picture is to look at everything close up” (Chuck, n.d.). His statement highlights a condition I call a myopic perspective. Myopia, or nearsightedness, is a condition in which a person can clearly see objects close-up while objects in the distance look blurry (“Myopia,” n.d.). A myopic perspective is a similar impairment limiting people’s psychological viewpoint or internal vision versus their physical…

Shot #1: I zoomed in on the roof of our chicken coop to illustrate horizontal lines. The chicken coop is built with all the lines listed, however, the longest of the lines, are horizontal. So, the horizontal lines made for the longest shot time. Shot #2: I focused in on the gold stitch, the other toys in the background blurred, creating the depth of field visual element. Shot #3: I zoomed in on tree bark at a local park to illustrate texture. Shot #4: I zoomed in on a building window arch to…

1) People who have a static disability that is not expected to worsen may be certified through a process referred to as a Statement of Demonstrable Ability (SODA). You may be able to get your vision test arranged so that you are tested on if you can differentiate airport lighting and ATC light signals. 2) 14 CFR 91.17(a)(3) says you must refrain from acting as pilot, or required crew member while on a medication, and until you no longer have symptoms. You can first ask yourself if this…
