Myopia

A study finds that 17% more Americans have myopia than 30 years ago. Close-up computer/screen work could be a reason. For an increasing number of Americans, life’s a blur. That’s according to a population-based study published Dec. 2011 showing that rates of myopia — difficulty seeing distant objects — are soaring. The trend is matched in many other countries, causing eye doctors to wonder what could be causing the decline in human vision.
