Is cataract related to drinking alcohol?

Generally, moderate alcohol consumption is not directly and inevitably linked to cataracts; however, long-term heavy drinking may increase the risk of developing cataracts. If you have concerns, it is advisable to consult a healthcare professional in advance. Detailed analysis is as follows:

If alcohol is consumed only occasionally and in small amounts, and if metabolic function is normal without issues such as liver damage or malnutrition, the impact of alcohol on the eye's lens is minimal. It will not directly cause lens opacity leading to cataracts. Maintaining a balanced diet and healthy lifestyle habits can help preserve eye health.

Long-term heavy alcohol consumption increases the metabolic burden on the liver, potentially causing impaired absorption of essential nutrients such as B vitamins, which are crucial for maintaining lens transparency. Additionally, excessive alcohol intake may disrupt ocular blood circulation, accelerate aging and clouding of the lens, thereby increasing the likelihood of cataracts—particularly among middle-aged and elderly individuals who face higher risks.

To protect eye health, it is important to control alcohol intake and avoid prolonged heavy drinking. Emphasize a balanced diet rich in vitamin-containing foods, and undergo regular eye examinations—especially for middle-aged and older adults—to detect and address any eye abnormalities early.
