Three visually impaired people walk into an ice cream parlor…

Tonight the person behind the counter read the flavors off to an 8-year-old girl and a man with a white cane. They didn't know each other, but both had strabismus (eyes that turn out from each other). The man bought the girl a milkshake and then a cup of ice cream for himself. I sat with him, introduced myself and told him I had low vision too but don't use a cane. He explained that in his home country of Argentina, people who are completely blind use white canes and people who are visually impaired but have some vision use green canes so that others know to ask, "How much can you see?" Argentina passed their Ley del Bastón Verde ("Green Cane Law") in 2002. Why not do the same in the US? It would help visibilize we the in-between, las personas con baja visión, or people with low vision.
