I read an interesting article from Rodale's Scuba:
A recent study suggest that if you had spent your childhood diving for sea cucumbers, you might have a better chance of seeing if your mask came off. The research showed that children of a tribe of nomads in SouthEast Asia known as the Moken see twice as well underwater without mask or gogles as European children do.
The Moken live on boats, the children pitch in diving for sea cucumbers and shellfish, and spend so much time under water without masks that their brains become adept at correcting water-blurred vision by changing the shape of their lenses and constricting their pupils.
You can't rule out genetics, but peliminary data suggests that it's learned," says Anna Gilsen if Sweden's Lund University. " The data says that it is possible that your children could learn this as well.
For landlubbers over the age of 40, it's probably too late to learn the process,
but a 25 year old could improve his vision with pratice. You can actually train more of your visual system more than you think," says Gilsen.
On the Discovery channel, I've seen people wear goggles that inverted their vision so that they saw everything upside down, and within 24 to 48 hours the brain adjusted their vision so that they saw right side up even with the goggles on. Also when people with crossed eyes have their eyes surgical corrected so that both pupil are looking straight, they have double vision for a few days until the brain has a chance to adjust. Alas, it too late for me, but maybe for some of you youngsters.
