It is a hospital-and-textbook word, not a kitchen-table word這是醫院和教科書裡會用的字，不是日常餐桌上會講的字

You would not say “my ophthalmic hurts”; you would say “my eye.” Though actually, English keeps several eye-words side by side, and learners often mash them together: ophthalmic is the medical adjective; the doctor is an ophthalmologist; the field is ophthalmology. None of these is the same as optional, which only looks a little like it on the page.
