Could you imagine, that people sitting next to you may see the common world not quite the same as you do? We offer you a compilation of different visual perceptions of people with visual disorders, in all ages and in various states that they can experience. Change the way you see things!
Physiological Differences in a Man’s and Woman’s Eyesight
A man and a woman have various physiological features that they differ in. Though, an eye structure is the same for both genders. It enables different visual capabilities for a man and a woman. It is believed that a woman has much wider peripheral vision than a man. It means that female eyesight permits catching objects around her in the sector of 45 up to 180 degrees on each side of the head. While a man has, what scientists call – a “tunnel vision”. He sees objects in front more focused and can easily track them farther ahead.
There’s an evolutionary explanation to that. Since ancient times a woman has been a “homemaker”, keeping the cave in safety and comfort. It was vitally important to quickly look around the cave, catch the details on both sides and detect the danger. On the other hand, primitive gender norms in the society, dictated males as “breadwinners”. Their role was to focus on a prey in front and keep an eye on it in order to attack.
A Picture of the World for People with Strabismus
It’s a common misbelieve that people with strabismus, also called crossed eyes, see the doubled objects or can see both sides at a time, like in movie scenes. Actually, the brain just ignores the information coming from one eye, so the picture won’t double. In other words, it is as seeing the world with one eye covered.
Eye Refraction Anomalies: Far-sightedness and Short-sightedness
In case of short-sightedness the background deliquesces and the foreground stays in focus. With far-sightedness it’s vice versa: the background with all the details remains clear, though the foreground appears blurry.
Visual Impairment: Nearly Complete Vision loss
Vision loss, unfortunately cannot be fixed by usual means, such as glasses. However, people suffering from nearly complete vision loss can distinguish abstract silhouettes, colors and light. Despite that, a nearly complete vision loss is equated to blindness in the society.
In Case of a Late Vision Loss
That’s how the people with partial color perception see the world: all they can discern is light and darkness. That usually true with people who have lost their eyesight in the conscious age.
Complete Vision Loss
A complete vision loss – is an absolute darkness. However, a blind person cannot identify the world around as “dark”, as they do not know what darkness is in general. People suffering with blindness since birth, do not have the usual visual night dreams but they dream of auditory, tactile and olfactory images.
Color Vision Deficiency
It is a decreased ability to see colors or to differentiate them. The most common form is deuteranomaly –the person is considered to be “green weak”. It means that dark green in the evening may appear to be black. Deuteranomalous people have troubles differentiating hues of red, orange and yellow. Individuals with protanomaly type of color blindness experience the color “brightness” problem.
Baby Vision: Right after the Birth
That’s how the baby sees the world after the birth: absolutely blurry. A newborn can only recognize the presence or absence of the light.
A Month after the Birth
During the first month a newborn is starting to distinguish large objects and objects at 7.8- inch distance (for example, mommy while feeding).
Six Month after the Birth
In 3 months a baby recognizes parents’ faces and by the sixth month can identify colors (especially well – red and yellow).
In the State of Alcoholic Intoxication
Of course we are talking about having more than a glass of wine. During alcoholic intoxication the decrease in cornea sensitivity and sheen reaction is commonly observed.
While Cannabis Smoking
While smoking cannabis, the world looks as if you were a bit drunk.
In State of LSD Use
The visual effects from LSD are very individual. Usually people experience “plume” effect behind the moving objects. Visual hallucinations are also very common.
The World “on Coke”
The movie “Limitless” gives a bit exaggerated effect of coke. Though, cocaine exacerbates all senses: the picture gets brighter and slightly distorted.
While Using Heroin
Any visual effects under the influence of this “disastrously-sweet” dope are not so important, as the euphoria possesses over the body and brain.
