                                According to a 2024 study, untreated hypothyroidism—often caused by severe iodine deficiency—is a causal determinant of age-related cataract risk in the European population. This highlights a potential, though indirect, link between **iodine deficiency** and the clouding of the eye's lens. While iodine is not a direct cause, its critical role in thyroid function suggests a potential connection to systemic metabolic issues that can influence ocular health.
