Could reading glasses soon be a thing of the past?

A thin ring inserted into the eye could soon offer a reading glasses-free remedy for presbyopia, the blurriness in near vision experienced by many people over the age of 40, according to a study. A corneal inlay device currently undergoing clinical review in the United States improved near vision well enough for 80 percent of the participating patients to read a newspaper without disturbing far distance vision needed for daily activities like driving.
