An ophthalmologist is a medical doctor who looks after eyes: checking sight, treating disease, and often doing eye surgery. The ending -ist points to a person, not to the subject. The subject itself is ophthalmology — that is the study.

An ophthalmologist眼科醫師 is是 a medical doctor一位醫師 who looks after eyes照顧眼睛: checking sight檢查視力, treating disease治療疾病, and並且 often doing eye surgery常常動眼睛手術。The ending結尾 -ist -ist指的是一個人 points to a person, not而不是 to the subject指那個學科。The subject itself這個學科本身 is是 ophthalmology ophthalmology(眼科學) — that就是 is the study那個學問。

In English-speaking clinics people also meet optometrists, who test sight and prescribe glasses, and opticians, who make and sell the glasses. Those are different jobs, though students (and even adults) often fold all three into one idea of 眼科. In Taiwan the everyday hook is 眼科醫師.

In English-speaking clinics在說英文的診所裡, people人們 also meet也會遇到 optometrists optometrists(驗光師), who他們 test sight and prescribe glasses檢查視力、開眼鏡處方, and而 opticians opticians(配鏡師), who他們 make and sell the glasses製作和販售眼鏡。Those這些 are不同的工作 different jobs, though不過 students (and even adults)學生(甚至大人) often fold all three into one idea常常把這三個都混成一個概念 of 眼科。In Taiwan在台灣, the everyday hook日常掛勾的說法 is是 眼科醫師。

This is a long, formal word; even native speakers trip on saying it. Though actually, if a line ever tells you this word “means the study of the eyes,” that line has slipped: the study is ophthalmology; this word is the doctor.

This這 is是 a long, formal word一個又長又正式的字; even native speakers連母語人士 trip on saying it都會唸得卡卡的。Though actually不過其實, if如果 a line一句話 ever tells you曾經告訴你 this word這個字 “means the study of the eyes,”"意思是研究眼睛的學問", that line那句話 has slipped就說錯了: the study那門學問 is是 ophthalmology ophthalmology(眼科學); this word這個字 is指的是 the doctor那位醫師。
