Myopia is the most common eye disorder in the world, affecting one in four Americans. Several studies indicate that myopia is inherited. Myopia is unknown among pure-blooded adult Eskimos. The majority have negligible refractive errors and a small number have low hypermetropia. Myopia is often accompanied by headaches, eyestrain, and fatigue when the person has to focus on something more than a few feet away.

Myopia is a refractive error faced my many people. It is not a disease but rather a condition caused by irregular eye shape. Myopia is a vision defect commonly known as nearsightedness . Those with myopia can see clearly up to a certain distance, then objects begin to appear fuzzy or out of focus. Myopia is expensive to treat if it is severe, and costly to the patient?s quality of life. Zhu?s study focused on myopia, building on previous research on genetic aspects and environmental factors.

Myopia is a common eye condition, and PRK is often used in correcting this axial elongation of the eye. Myopia is a refractive error, like astigmatism. It can be controlled by wearing glasses or contact lenses. Myopia is a common trait that is increasing in incidence and is strongly heritable. Four loci have been identified from a genomewide linkage analysis, with the highest peak on chromosome 11p13 (LOD 6.1).

Myopia is more common than hyperopia; among Americans over the age of 40, about 30 million have myopia and at least 12 million have hyperopia. While the prevalence of myopia decreases with age, that of hyperopia increases. Myopia is now ranked in the top five causes of blindness in some Caucasian countries, rising to number three in East Asian countries where its prevalence is already high. Myopia is caused when the shape of your eye is slightly longer than usual . Because of this, your eye is unable to focus light from objects at a distance onto the retina, the light sensitive area at the back of the eye.

Myopia is a symptom of disciplinary thinking. It forces conversations about interdisciplinarity to be framed within predominantly spatial terms. Myopia is a very serious disease that can have a tremendous effect on the life of a child. Approximately 5.6% of blindness among American school children can be attributed to myopia. Myopia is a common eye problem in which the eyeball is too long so that light rays focus in front of instead of on the retina (Figures 1 & 2). Eye that has refractive error equal or greater than -6.0 Diopters (600 degrees) is classified as “high myopia”.

Myopia is a very common condition, affecting about 1 in 4 people. As well as the inconvenience of having to wear spectacles or contact lenses, myopia is a risk factor for a number of eye diseases. Myopia is best treated with eyeglasses and contact lenses which compensate for the elongated shape of the eye allowing the light to focus properly on the retina. As children (and their eyes) grow through the teen years, the condition typically worsens and then levels off in adulthood.
