I saw this recently on 23andMe – New 23andMe+ Report on Nearsightedness: https://blog.23andme.com/health-traits/nearsightedness-report/. Much longer article. but here are some of the relevant portions. December 8, 2021 By 23andMe under Health and Traits
The number of people who are nearsighted, who need glasses to see distant objects clearly, has risen dramatically over the last 50 years.
Known as myopia, nearsightedness is quite common, and occurs when the shape of the eye is elongated or the cornea of the eye is angled in a way that prevents the eye from focusing light properly. It’s estimated that about 45 percent of adults in the U.S. aged 20 and older are nearsighted. In many parts of East Asia, the rates are much higher than that.
This week, we released a new 23andMe+ report (Powered by 23andMe Research) that looks at a person’s likelihood of being nearsighted and provides information about the condition as well as ways to protect your vision.
