Okay, the user wants me to translate "eye-lash" into Russian. Let me check the rules again. The first rule says to translate all content into Russian. The second rule states that if the content is already in Russian, leave it as is. The third rule is to provide only the translation without explanations.
So, "eye-lash" is an English word. The Russian translation for "eyelash" is "ресница". I need to make sure there's no typo. Let me confirm: "ресница" is the correct spelling. The user might be looking for the singular form, which is "ресница", as opposed to the plural "ресницы". Since the input is singular, the translation should be singular as well. No other rules apply here. Just output "ресница".
