3 blocks for the many trackers (and possible ads) on their website.

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/)

Mazava ho azy fa mahafinaritra ny manome fandidiana katarakta mora vidy ho an'ny mahantra, saingy tsy maimaim-poana izany. Noho izany dia tsy afaka manome azy ireo bloc 5/5 aho, na dia toa fikambanana lehibe manana fikasana tsara aza izy ireo.
