So I found out they do provide trade-free goods: “Since 1994, Helen Keller International has provided free vision screenings for more than 2 million children in the United States and provided more than 300,000 of them with prescription eyeglasses to solve common vision problems.” – but they also provide access to some trade-based services: “We are improving access to high-quality, affordable cataract surgeries for poor and remote communities in under-served regions of Asia.” (https://www.hki.org/what-we-do/saving-sight/)
