Maybe I'm too greenly, because my Chinese is bad - but doesn't it say something with eyes?

Yes, 安眼药 means sleeping pills. However this leads me to a question of my own... I learnt this word in one of my text books, and I didn't notice this before but it actually says here that the pinyin is "ānmiányào". I have only ever seen the character 眼 pronounced as "yǎn", and in my dictionary it also gives "yǎn" as being the only pronunciation of 眼. Is "ānmiányào" incorrect or can 眼 also be pronounced as "mián"?

the correct words are：安眠药 an1 mian2 yao4 眠=sleeping （we can say：睡眠） so it's not about 眼（eyes） at all

Sleeping pills or hypnotics, but you should change 眼 to 眠，哈哈

it should be "安眠药" （an1 mian2 yao4） “眠” and "眼" are different , but easily be confused , because they look similar , so you should pay attention to the two characters "眠" , it is "民"(min2 , 人民的民) , in the right “眼”, "艮" （pronounce “gen3” or "gen4"） in the right
