> handing out a $5 pair of sunglasses would prevent the cataracts in the first place (these are pretty much all UV induced).
I've also heard that vitamin sufficiency prevents UV induced cataracts, is this true and on what scale would vitamins be sufficient? Introducing a particular crop with the particular vitamin to the local farmers, potentially a GMO crop, or selling supplements or adding vitamins to food (e.g. in the Netherlands I know virtually all bread has government-encouraged iodine to prevent iodine deficiency illnesses and effects, not sure if it's a worldwide standard, but iodising table salt is common practice for the majority of the world, too) might be a practical alternative.
