Following are a number of back-translations as well as a sample translation for translators of Proverbs 10:26:

  like how smoke disturbs the eyes, or like when bitter fruits are eaten.” (Source: Kupsabiny Back Translation)
• Newari: “Getting lazy people to work is like
  vinegar to the teeth
  and smoke to the eyes.” (Source: Newari Back Translation)
• Hiligaynon: “As vinegar can-cause- the teeth -to-set-on-edge and smoke can-cause- the eyes -to-become-bitter, the lazy man can-cause-vexation to the one who commands him.” (Source: Hiligaynon Back Translation)
• Kankanaey: “The lazy-one in the viewpoint of his master can-be-compared to vinegar that tastes-sour/tart and smoke that is-sour/bitter to the eyes.” (Source: Kankanaey Back Translation)

  just like we do not like vinegar in our mouths or smoke in our eyes.” (Source: Translation for Translators)
