In China, though, one in three needs to wear spectacles from primary school age on. It is because of poor lifestyle choices. Too few hours spent outdoors, too many spent in poorly lit rooms. They think the brighter the light the better for their eyes, or the light is too dim.
Belgium who was number 1 for glasses wearers at 70% only comes in at number 6 for contact lens wearers with just 10% of it's population choosing to wear contact lenses (8), whereas North Macedonia which shared the top slot for glasses shares the top slot again for contact lenses with 30% of its population wearing ...
White and Asian people are more likely to wear them than their Hispanic and Black friends. Low-income folks are less likely to wear glasses than high-income ones. And Northeasterners and Midwesterners are more likely to wear glasses than Southerners and Westerners.
The high prevalence of myopia in Chinese ethnic groups may have something to do with the genetic factors, and the observation had evidenced that myopic parents are more likely to give rise to offspring with myopia (Tab. 2) [18].
The first eyeglasses are believed to have been made in the Italian city of Pisa in about 1290. However, the precursors of spectacles can be traced back to the Eastern Han Dynasty (AD 25-220) in China.
Early Glasses
The first wearable glasses known to history appeared in Italy during the 13th century. Primitive glass-blown lenses were set into wooden or leather frames (or occasionally, frames made from animal horn) and then held before the face or perched on the nose.
Italian monks were the first to craft semi-shaped ground lenses in the 13th century, which worked like magnifying glasses. To make the lenses, the monks used a type of quartz called beryl.
China's myopia rate is 31%: 400 million of its 1.3 billion people are myopic. The prevalence of myopia in high school in China is 77%, and in college is more than 80%. In some areas, such as China and Malaysia, up to 41% of the adult population is myopic to 1.00 dpt, and up to 80% to 0.5 dpt.
Asian Americans and Pacific Islanders (AAPI) descend from over 20 countries, making up 7% of the U.S. population (around 20 million). They're at higher risk for some eye conditions, including myopia, diabetic retinopathy and angle-closure glaucoma, and complications of hepatitis B and tuberculosis.
Wearing glass is a safe and effective treatment for myopia, but evidence suggests that only 15–20% of rural and urban migrant children in China who need glasses have them. [10, 11] Most of this evidence, however, is drawn from children of Han ethnicity, a group comprising more than 90% of China's population.
Astigmatism ran fairly high in each group, with Hispanic children having the highest prevalence (37 percent), followed by Asian children (34 percent), white children (26 percent) and, finally, African-American children (20 percent.)
Among all ethnic groups, Black Americans suffer the most from glaucoma and other eye diseases. In 2011, the Glaucoma Research Foundation found that glaucoma is the primary cause of blindness among African Americans. They are 15 times more likely to experience a loss of vision caused by glaucoma than white Americans.
But environmental factors also influence eyesight, especially when people are young. One of the biggest connections is between education and myopia, with more years of schooling, time spent studying, and even higher academic grades linked to increased myopia.
49.5% of the Australian population wear glasses or contact lenses (2). 53.7% of Australians suffer from one or more long-term eye conditions (2). Long-sightedness up 4% to 26.4% (2). Short-sightedness up 2% to 22.9% (2).
AIHW media releases
More than half (54%) of all Australians report having at least one long-term eye health condition, with nearly half the population wearing glasses or contact lenses, according to data released today by the Australian Institute of Health and Welfare (AIHW).
The majority of adults in Japan regularly wore eyeglasses or contact lenses as revealed in a survey conducted in December 2021. Glasses were the preferred items, with 31.1 percent usually wearing glasses and another 26.5 percent wearing them when necessary.
There are plenty of blue-eyed Asians. This probably happens when the traditional blue-eyed allele comes into a family from a (possibly very distant) European ancestor. Blue eyes then resurface in a child generations later if they inherit the allele from both parents.
The prevalence of myopia was 3.5%, 4.4% and 4.3% in 2014, 2016 and 2018, respectively. The prevalence of myopia increased with age (P<0.0001), but was not related to sex or year of testing (all P >0.05). The overall mean SER was 0.89±0.86D, 0.62±0.89D and 0.56±0.95 in 2014, 2016 and 2018, respectively.
It seems that the best eyesight ever reported in a human was in an Aborigine man with 20/5 vision! To give you an idea of how clear and far he could see, his vision measurement compares to the natural sight of eagles. From 20 feet, he could perceive the fine details that most people can only see from 5 feet away!
The high childhood myopia rate in Singapore is largely attributed to frequent near-work activities done with handheld gaming devices, personal computers, mobile phones and iPads, according to a study by the Singapore Eye Research Institute, Prof Lee said.
The first eyeglass was invented during the 13th century, but even before that people were already suffering from poor vision. Nearsightedness and farsightedness were quite common. In fact, historical accounts exist of people suffering from poor eyesight.
Nowadays, about 90% of all eyeglasses are made in China.
Wenzhou, Zhejiang is the most famous area of eyewear manufacture after Shenzhen. And the Wenzhou Optical Fair (WOF) is become popular. The main products are #eyeglasses, #optical frames, especially acetate frames. Besides, the metal model is also good in quality.
