One discussion guide, four markets: researching online lens buying

An eyewear online-retail team partnered with CleverX to learn how people shop for prescription lenses online. The goal was comparable insight across four language markets at once, run as one discussion guide translated into four languages, each with a natural-sounding voice for that market.

• The team needed comparable insight across four markets, not four disconnected studies.
• The detail on lens types and coatings had to survive translation without losing meaning.
• Each market needed a voice that felt native, not just translated words read aloud.

CleverX ran one guide with identical logic across four localized versions.

• One 21-question guide was translated into four languages.
• The screener logic stayed identical in every market to keep results comparable.
• Each market got a natural-sounding AI voice suited to that language.
• One market's version covered several countries at once where the same language is spoken.

• 20 interviews completed across all four markets.
• Full completion in three markets, plus a strong qualification rate on the larger market.
• A consistent pattern emerged across markets, with one add-on option clearly the most wanted.

• The guide should stay constant while language and voice are the things that change.
• A native-sounding voice per market matters for participant comfort and answer quality.
• Running small markets alongside a large one in a single structure is an efficient way to get a global read.
