NEARSIGHTEDNESS CAUSED BY not enough sun? “Researchers suspect that bright outdoor light helps children’s developing eyes maintain the correct distance between the lens and the retina — which keeps vision in focus. Dim indoor lighting doesn’t seem to provide the same kind of feedback. As a result, when children spend too many hours inside, their eyes fail to grow correctly and the distance between the lens and retina becomes too long, causing far-away objects to look blurry. . . . Luckily, there is a simple way to lower the risk of nearsightedness, and today, the summer solstice — the longest day of the year — is the perfect time to begin embracing it: get children to spend more time outside.”

So can we sue the health-nannies who told everyone to keep their kids out of the sun? You know, the way people would be trying to go after pharmaceutical companies that caused similar degrees of harm?
