[PureInsight.org] In Africa, there are primitive tribes that depend on hunting for their livelihood. They have excellent eyesight. Many of them surpass the 2.0 standard power of sight, with some achieving 3.0 and even reaching 5.0 power levels. The power of sight denotes the distance from which a person can distinguish a standard sized object. The standard power of sight is 1.0. For example, a person with 1.0 as the standard can see at a distance of 1 meter. So, a person with a 3.0 power can see it at a distance of 3 meters away and if the standard of sight is 5.0 a person can see the object at a distance of 5 meters away.
Why do the primitive tribes have such good eyesight? It is related to their livelihood. They live in a primitive environment without any advanced and modern tools. If their eyesight is not good enough, hunting will be a problem for them.
Conversely, we are living in modern cities with high technology, where numerous tools are being invented continuously. These tools make our lives much easier, but modern peoples' bodies have degenerated and are gradually becoming weaker. A high ratio of primary school students suffer from near-sightedness and the ratio worsens with age.
The decline of the physical capabilities of the human body is related to the development of automated machinery. It can be noted that the inventions of the train and the automobile have undoubtedly solved the problems of long distance travel for the human race. Gradually, however, the human race has lost the physique for walking and riding a horse. Modern humans know that walking and riding a horse are exercises beneficial to the body. They assist in the loosening of the joints, stretching and strengthening of the muscles.
