Children who see like dolphins An experiment showed that children of a Thailand tribe could see clearly beaneth the sea, while adults didin't have the same ability. The reason as to why this happes is that children's eyes are more likely to adapt and change their shape. These children from Thailand were used to always swim and fish, so it was a easy job for their eyes. This experiment was also made with European children and the result was similar: if these children keep trying to see underwater they'll eventually have the same capacity than children from Thailand. However, this is not truth when we talk about adults since they lose the ability to see clearly as children. I have to agree with that because I used to see much better underwater when I was younger and now it just seems I am not as good as I was. Hence, It's probably easy for kids see underwater.
