Talk about being clear-eyed!
Mermaids aren't the only ones who can see under water! The semi-nomadic Moken people of Myanmar and Thailand harvest fish with traditional methods—just without the goggles and masks.
As unbelievable as it sounds, the Moken people are able to gather shellfish at depths of 75 ft without any sort of eye covering. This practice can be explained through studies of Moken children, who have twice the clarity of underwater vision as European children of the same age.
