Prevalence of myopia
U.S. myopia prevalence is considered to be 42 to 46 percent with a 68 percent increase in 20 years.1
“That number is likely even higher now because those numbers come from a 2009 study,” says Dr. Sclafani.
In addition, those with higher myopia (>-8.00 D) is projected to have an eight times increase.
According to the Brien Holden Vision Institute (BHVI), worldwide myopia prevalence varies:
• U.K.: 32 percent
• Canada: 72 percent
• Europe: 42 percent
• China: 95 percent
• Taiwan: 84 percent
• Singapore: 81 percent
• South Korea: 96 percent
BHVI projects the number of myopes to continue to increase to 2.5 billion by 2020 and 5 billion by 2050. By 2050, the number of myopes greater than 5.00 D will reach 900 million—increased from 200 million in 2010.
