少年儿童自我防范意识缺乏,不懂得防护自己的眼睛,常容易发生眼外伤。 正常人的晶体纤维被一个半通透性的晶体囊袋保护着,房水不能进入。一旦囊袋破裂,房水渗入后直接与晶体蛋白接触,晶体纤维即可发生肿胀和混浊——即发生外伤性白内障。无论是机械性、化学性、热性和放射性的眼睛 Children lack of awareness of self-protection, do not know how to protect their own eyes, often prone to eye injuries. Normal human crystalline fibers are protected by a semipermeable crystal pocket, aqueous humor can not enter. Once the capsular bag is ruptured, aqueous humor infiltrates directly into contact with the crystalline protein, which can cause swelling and opacity in the crystalline fibers - traumatic cataracts. Whether mechanical, chemical, thermal and radioactive eyes
