我每次上完网都滴一次，是不是滴多了也不好？
推荐回答（2个）
每次上完网都滴一次没事.但不能频繁的滴.
一下摘自百度知道:
1.我看过很多医学报道，都说其实眼药水点多了对眼睛是不好的，尤其
是那种杀菌消炎类的眼药水。所以不是有治疗必要在医生指导下最好不
要随便使用眼药水。
其实眨眼睛就是有湿润眼球的作用，看电脑不要忘记眨眼睛，用眼过度
的时候做做眼保健操就可以了。
2.眼药水滥用弊病多 大多数含防腐成分
眼药水是眼科疾病最常用的药物剂型之一，对于许多眼病，眼药水都有直接、快捷的治疗作用。然而，许多人没有眼疾也习惯经常点眼药水，或者眼部不适、不经确诊就点眼药水。专家提醒，这都是不合适的，滥用眼药水弊病多。
据黑龙江中医药大学临床医学院孙河教授介绍，绝大多数眼药水除了其治疗成分外，还含有防腐成分。如果经常滴眼药水，防腐成分可破坏眼表结构，产生刺激症状。抗生素眼药水是应用最广泛的，包括针对细菌感染、病毒感染、真菌感染、衣原体感染等。这类眼药应在医生的指导下按疗程用药，如盲目地长期使用抗生素眼药水会引起耐药菌株的产生。
孙河教授说，眼药水根据其成分的不同，其治疗作用不同，如果不经确诊自己经常点某种眼液，会引起不良后果，有些后果也是非常严重的。如：有人眼睛干涩不适，当用了糖皮质激素类的眼药水，立即感觉舒适，于是经常上这种眼药水，由于这类药物能抑制免疫机能，可能引起严重的感染甚至角膜穿孔，这类药物还可能引起激素性青光眼等严重后果；有些眼药水含有收缩血管的肾上腺素，当眼睛充血时用了马上充血消退，这是肾上腺素收缩了血管，并未去除充血的病因，当药效过去了，充血依旧。一些人于是频频滴用，这种强力收缩血管的药物，影响眼的代谢，很可能加重眼病。
专家提醒：用任何一种药物都应有针对性，要在医生的指导下，按疗程用药。更重要的是养成良好的卫生习惯，生活要有规律，科学用眼，增强体质，避免眼病的发生。
