Presbyopia

The ability to see things up close is dependent on the natural lens of the eye (crystalline lens) changing its shape to accommodate every distance you’re looking at. Over the age of 40 the lens’s ability to change its shape diminishes and people find that “their arms have gotten to short”. A study published by Archives of Ophthalmology in Dec. of 2008 reported that “more than 1 billion people worldwide had age related presbyopia. The authors predicted that by 2020 563 million people worldwide will have disability associated with uncorrected presbyopia.
