Multifocal contact lenses improved visual performance in young adults and those with presbyopia, despite small but consistent degradation, according to a study published in PLoS One.
“The present study reveals that center-near lenses do not degrade high contrast
visual acuity significantly while maintaining far vision in young adults and produce some
visual benefit at near in presbyopes,” Shrilekha Vedhakrishnan, a predoctoral researcher at the Institute of Optics in Madrid, and colleagues wrote. “Factors such as visual degradation at far, visual benefit at near and visual
