Discordance between measured and perceived vision in older adults: the need for objective screening despite health consciousness.

Associated factors were examined at the eye level using generalized linear mixed-effects models.

Discordance was substantial: 47.2% of OVI eyes did not report SVD, whereas 38.5% of non-OVI eyes reported SVD.

Higher income and lower Self-Rating Anxiety Scale (SAS) scores were associated with OVI without SVD, while lower income and higher SAS scores were linked to non-OVI with SVD; unilateral OVI was also associated with OVI without SVD.
