Blue-Light Glasses: What the Cochrane Review Found
Seventeen randomised trials, and no reliable evidence that blue-filtering lenses reduce eye strain. The physics is the more interesting part: the lenses block roughly eight percent more blue light than the clear ones.
The people who found the Blue Zones are quietly walking them back
Nicoya’s advantage inverted in forty years. Okinawa fell from 4th to 26th. And the researchers conceding this are the ones who identified the zones in the first place.

The latte factor gets the arithmetic right and the mechanism wrong
