"Older adults who wear multifocal contact lenses to correct problems with near vision, a very common condition that increases with age, may have greater difficulty driving at night than their counterparts who wear glasses, says a new study [published in Investigative Ophthalmology and Visual Science]," according to post on Sify. "The study suggests that wearing multifocal contact lenses resulted in significantly slower driving speeds at night than wearing progressive addition glasses, which authors reported a reduced ability to recognize road hazards." There were other findings as well.
