The vision of Leonardo da Vinci

A little-known fact is that although only about 100 years ago, but contact lenses were born from the idea of inventor Leonardo da Vinci. He sketched this idea in his 1508 book Codex of the Eye in 1508, where submerging a person’s head in a bowl of water could change their vision. He even created a glass tube with a large funnel on one side to fill it with water. However at that time, his way of thinking was unrealistic and quite absurd.
