Now researchers at Duke Medicine are closer to clearing this up. Mutations in a gene that helps regulate copper and oxygen levels in eye tissue are associated with a severe form of nearsightedness, according to a study published in the American Journal of Human Genetics. Nearsightedness – also known as myopia – is the most common human eye disease in the world… (Source: Health News from Medical News Today)
