Improved eyesight naturally makes happier

Naturally, improved eyesight makes people happier
A person who sees unclear is not that happy about life, because everything is blurry around him.
People who improve vision naturally, like me got a perception of the world as more colorful, contrast, and bright. A person becomes more confident when he understands how his eyes work.
It happens that the person who lived all his life did not know about that they can see so colorful and clear world around them
The world is huge and beautiful and it is really nice and pleasurable to see it clearly well. It is a different feeling when you walk by the streets and you can see everything you look at.
