×I need to clean my glasses lens.
✓I need to clean my glasses lenses.
眼鏡通常有兩個鏡片，因此應使用複數形式 'lenses'。單數 'lens' 僅指單一鏡片。
×Look at the problem through a different lens.
✓Look at the problem through a different lens.
此句文法正確，但學習者常誤以為 'lens' 在此為可數名詞，應使用複數。實際上，此為比喻用法，單複數皆可，但強調單一觀點時常用單數。
×The camera's lens is very expensive.
✓The camera lens is very expensive.
使用所有格 's 時，通常表示所屬關係（如 the camera's battery）。但 'camera lens' 是一個複合名詞，直接組合更為自然，類似 'car door' 而非 'car's door'。
×I have a contact lens in my right eye.
✓I have a contact lens in my right eye. / I wear contact lenses.
句子本身正確，但學習者常混淆單複數使用情境。指單一片時用 'a contact lens'，但通常指佩戴隱形眼鏡時，會使用複數 'contact lenses'，因為雙眼都會佩戴。
×This lens magnify the image.
✓This lens magnifies the image.
'Lens' 是單數名詞，其後的動詞需使用第三人稱單數形式。
