Incident cataract was ascertained through hospital inpatient and self-reported records. SES was derived from household income, employment and education using latent class analysis, while CVH was assessed via the Life\u2019s Essential 8 (LE8) score. Cataract risk was evaluated using multivariable Cox regression, with interaction and joint effects analyses performed to assess the interplay between SES and CVH.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>This analysis involved 236\u2009248 participants with an average age of 55.5 years (range: 38\u201373); 51.6% were female and 95.6% were of white ethnicity. Over a median follow-up period of 11.7 years, 26\u2009791 participants (11.3%) developed cataract. Compared with the high SES group, participants with low SES had a significantly higher risk of cataract (HR, 1.30; 95% CI 1.25 to 1.35). Significant additive and multiplicative interactions between SES and CVH on cataract risk were observed. Better CVH substantially mitigated the adverse association of low SES with cataract. Notably, individuals with low SES and poor CVH showed the highest cataract risk (HR, 1.74; 95%\u2009CI 1.57 to 1.93) in contrast to those with high SES and optimal CVH.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Implementing interventions aimed at enhancing both SES and CVH may prove beneficial in preventing or delaying cataract onset.
