The Prevalence and Demographic Association of Presenting Near-Vision Impairment Among Adults Living in the United States
The purpose of this study was to determine the prevalence of presenting near vision impairment among adults in the United States.
This was a cross-sectional study conducted with 11 016 of 12 781 (88.5%) US adults.
The prevalence of presenting near vision impairment was present in 13.6% of participants.
The high PNVI was associated with nonwhite race, older age, male sex, less than high school education.
High PNVI was also associated with lack of private health insurance, income less than poverty level, lacking/not using near-vision correction at time of examination, and impaired distance vision.
Lack of near correction was associated with nonwhite race, younger age, male sex, and lack of access to health care.
