In water the world becomes blurry.
As you descend, light
levels
drop quickly. Your eye
reacts
by opening the iris, making the pupil larger and allowing more light in. The image becomes
brighter
, but under water a larger pupil also makes the image more blurred.
But Goon has learned how to overrule this
automatic
reflex with an astonishing
adaptation
seen clearly with the help of an infrared camera. Instead of opening his pupils, he closes them as far as they will go. This means Goon can see
twice
as well under water as you or I.
Recent studies
suggest
that any child can quickly learn this trick.
The Moken show how well the human brain can
adapt
the body to suit its needs. This adaptability has
enabled
our species to thrive on all seven of Earth’s continents.
