Poor depth perception, which means not being able to see things in three dimensions and judge how far away an object is.This is called misrouting of the optic nerve. Nerve signals from the retina to the brain that don't follow the usual nerve pathways in the eye.This difference results in reduced vision. Differences in the development of the thin layer of tissue on the inside back wall of the eye, called the retina.A difference in the curve of the front surface of the eye or the lens inside the eye, called astigmatism, which causes blurred vision.Extreme sensitivity to light, called photophobia. Problems seeing near objects or far objects, called farsightedness or nearsightedness.Eyes that can't look at the same direction at the same time or they appear to be crossed, a condition called strabismus.An uncommon head position or head posture, such as tilting the head to try to reduce eye movements and see better.Rapid, back-and-forth movement of the eyes that can't be controlled, called nystagmus.Vision problems are a key feature of all types of albinism. Because of this, very light-colored eyes may appear red in some lighting. This allows light to shine through the irises and makes the eyes extremely sensitive to bright light. With albinism, the colored parts of the eyes, called the irises, usually don't have enough pigment. Eye color can range from very light blue to brown and may change with age. Eye colorĮyelashes and eyebrows are often pale. Or hair may stain from contact with minerals in water and the environment, making hair appear darker with age. Hair color also may darken by early adulthood. People of African or Asian descent who have albinism may have hair color that's yellow, red or brown. Hair color can range from very white to brown. For others, melanin production may begin or increase during childhood and the teen years, resulting in slight changes in color. Large freckle-like spots, called solar lentigines (len-TIJ-ih-neez).įor some people with albinism, skin coloring never changes.Moles, with or without color, which are sometimes pink.With exposure to the sun, some people may develop: For some people, skin color may be nearly the same as that of parents or siblings without albinism. People of African descent who have albinism may have skin that is light brown or red brown and have freckles. But skin coloring, also called pigmentation, and hair color can range from white to brown. The easiest form of albinism to see results in white hair and very light-colored skin compared with siblings or other blood relatives. The difference between actual output and potential output when an economy is producing less than full employment output when there is a negative output gap, the rate of unemployment is greater than the natural rate of unemployment and an economy is operating inside its PPC.Symptoms of albinism involve skin, hair and eye color, as well as vision. The difference between actual output and potential output when an economy is producing more than full employment output when there is a positive output gap, the rate of unemployment is less than the natural rate of unemployment and an economy is operating outside of its PPC. The straight line in the business cycle model, which is usually upward sloping and shows the long-run pattern of change in real GDP over time The level of output an economy can achieve when it is producing at full employment when an economy is producing at its potential output, it experiences only its natural rate of unemployment, no more and no less. When GDP begins to increase following a contraction and a trough in the business cycle an economy is considered in recovery until real GDP returns to its long-run potential level. The turning point in the business cycle between a recession and an expansion during a trough in the business cycle, output that had been falling during the recession stage of the business cycle bottoms out and begins to increase again. The turning point in the business cycle between an expansion and a contraction during a peak in the business cycle, output has stopped increasing and begins to decrease. The phase of the business cycle during which output is falling The phase of the business cycle during which output is increasing The total supply of goods and services produced by a nation’s businesses The total demand for a nation’s output, including household consumption, government spending, business investment, and net exports A model showing the increases and decreases in a nation’s real GDP over time this model typically demonstrates an increase in real GDP over the long run, combined with short-run fluctuations in output.
