Okay, the user wants me to translate "eye-lotion" into Vietnamese. Let me check the rules again. The first rule says to translate all content into Vietnamese. The second rule states that if the content is already in Vietnamese, leave it as is. The third rule is to provide only the translation without any explanations.
So, "eye-lotion" is in English. I need to translate it. The direct translation would be "dung dịch nhỏ mắt" in Vietnamese. Let me confirm that. "Dung dịch" means solution or liquid, and "nhỏ mắt" is eye drop. That seems correct. I don't think the user provided any Vietnamese text here, so I don't need to leave it unchanged. Just make sure to output only the translation. No explanations, just the result. Alright, that should be it.
