常見錯誤

❌She hurt her retina when putting in contacts.
✅She hurt her cornea when putting in contacts.
💡The retina is at the back of the eye; the cornea is the clear front layer.
❌He had a cornea transplant in his both eyes.
✅He had a cornea transplant in both eyes.
💡'His both eyes' is not grammatical; use 'both eyes' or 'both of his eyes'.
