常見錯誤
❗ 'Look at the eyepiece' (when the intended meaning is looking through it). ✅ 'Look through the eyepiece.' — 'at' suggests examining the object itself; 'through' describes using it to see something else.
❗ 'Change the eyepiece of the telescope to a stronger lens' ✅ 'Replace the eyepiece with a stronger one.' — 'change [part] of [thing] to [thing]' sounds unnatural for optical components.
