近日，一则‘小伙平均每天喝半斤酒，双眼突然失明’的新闻引发广泛关注。据医生介绍，该男子长期大量饮酒，导致体内维生素B1（硫胺素）严重缺乏，进而引发一种名为‘营养性视神经病变’的疾病。这种病症会损害视神经，造成视力急剧下降甚至永久失明。专家指出，酒精不仅直接损伤肝脏和神经系统，还会干扰人体对关键营养素的吸收与代谢。尤其是维生素B1，在能量代谢和神经功能中起着至关重要的作用。长期酗酒者若饮食不均衡，极易出现此类营养缺乏问题。医生提醒，每日饮酒量应严格控制，男性建议不超过25克纯酒精（约相当于50毫升白酒）。一旦出现视力模糊、视野缩小等症状，应立即就医。戒酒、补充维生素并调整饮食结构是治疗和预防的关键措施。
Recently, news of a young man who suddenly went blind after drinking an average of half a kilogram of liquor daily has drawn widespread attention. According to doctors, his prolonged heavy alcohol consumption led to a severe deficiency of vitamin B1 (thiamine), triggering a condition known as nutritional optic neuropathy. This disorder damages the optic nerve, causing rapid vision loss and potentially permanent blindness. Experts explain that alcohol not only directly harms the liver and nervous system but also interferes with the body’s absorption and metabolism of essential nutrients—particularly vitamin B1, which plays a vital role in energy metabolism and nerve function. Individuals who drink heavily over long periods and maintain poor diets are especially vulnerable to such deficiencies. Physicians advise strictly limiting daily alcohol intake; for men, it should not exceed 25 grams of pure alcohol (roughly equivalent to 50 milliliters of baijiu). Anyone experiencing symptoms like blurred vision or reduced visual field should seek immediate medical attention. Key treatments and preventive measures include abstaining from alcohol, supplementing vitamins, and adopting a balanced diet.
