Sponsor's own description

Near vision deterioration during aging results from a decrease in accomodation amplitude (AA). Myocardial regeneration is limited, and cardiac aging is an independent risk factor for cardiovascular disease. Thus, the investigators investigated the association between cardiac aging and AA. The subjects (500, mean 50-year-old subjects, with equal males and females) were divided into two groups according to AA measured with a Raf ruler. Biomicroscopy was used to capture images of the lens nucleus in the unaccommodated state, followed by images of a 4 diopter (D) accommodated state. The nucleus diameter change at 1 D accomodation was measured using ImageJ. Cardiac conduction system differences were evaluated using electrocardiography, and cardiac autonomic aging was assessed based on heart rate variability. Myocardial aging was assessed based on diastolic dysfunction.
