NHANES captures nationally representative samples of the U. To complicate matters, the methodology for measuring myopia also changed over the years.

In the 1970s, detailed measurements were taken only on participants with more severe refractive error, and those were made through retinoscopy, a manual observation of how different strengths of corrective lenses affect the reflections bounced off the retina.

Variations in myopia prevalence among different ethnicities suggest a genetic contribution of some sort. Asian and Hispanic participants were found to have higher prevalence of myopia (18.5% and 13.2%, respectively) than black and white children (6.6% and 4.4%, respectively).17For Mutti, who was part of the CLEERE Study Group, such data can suggest genetic links to myopia but say little about the nature of those links and how they determine prevalence.Research drawing on data from the 1999–2004 iterations of the National Health and Nutrition Examination Survey (NHANES) estimates that U. myopia prevalence can range from 33.1% across the entire adult population to as little as 25.1% for Mexican Americans.13 By comparison, one study of myopia in Singaporean Chinese, Malay, and Indian adults reported rates of 38.7%, 26.2%, and 28.0%, respectively.12Myopia may not be as grave a health problem as cancer or heart disease, but there is more at stake than a population saddled with the expense and inconvenience of coping with glasses or contact lenses.Studies suggest the condition may be a risk factor for more serious eye problems including cataract14 and glaucoma,15 although myopia’s relationship to these other problems is still unclear.But you do not see children of school age, because they are at home doing their homework,” he says.This lifestyle appears to exact a toll on young eyes.

  1. Your standard Linux distribution may be able to perform some audio recording tasks, but sometimes, it helps to have a tuned system from the get-go; this is especially important in those cases where one just wants to get to the business of sound as quickly as possible.

  2. I'm a very easy going, down to earth country girl; enjoy working on tractors, off roading, and on quiet nights watching a movie...... If you wanna have a good time you gotta hit me up BOYS and I'll show you what a good time is. My friends say I'm crazy but I say I'm just living my life. I'm not very good at these types of things..I'll just give it a shot. Evenings out are good, but evenings in cuddled up on a couch are even better.
