The association exists in observational studies (those with poor vision have a higher risk), and the mechanism is plausible — less stimulation, more isolation, less activity — but the trials that would prove the preventive effect do not yet exist. Scientific honesty requires us to say so. But screening and treatment are still recommended The WHO's general guidelines maintain that vision screening should be offered to all adults, and treatment to those with diagnosed problems. In the specific case of cataracts: surgery is one of the interventions with the best benefit-risk ratio in all of medicine — quick, safe in the vast majority of cases, and transformative.
