A new survey sponsored by CooperVision and conducted by Harris Interactive (R) found that 83% of U.S. adults aged 18 years and above are not aware of a vision condition called presbyopia, which inflicts nearly 90 million Americans, or roughly one in three people. The survey also found that only 27% of the U.S. adults aged 18 years and above expect to need bifocals or reading glasses, which is the most common correction for people facing presbyopia.
