"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 released at AAO 2014, the 118th annual meeting of the American Academy of Ophthalmology," reports Science Daily. "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. ...One of the devices is the Kamra inlay, a thin, flexible doughnut-shaped ring that measures 3.8 millimeters in diameter, with a 1.6 millimeter hole in the middle.
