HOW VIDEO GAMES ARE GOOD FOR VISION ? (ESPECIALLY FIRST PERSON SHOOOTING GAMES)

In every day life parents always scold or shout on their children for playing video games a lot. They always say that these video games may affect their eyes and their eyesight become weak, and parents also says that by eating carrot they can increase there focus and vision. But recent studies that playing video game  increases the vision of person. 

ANSWER :- 

This may be a stretch, but studies are currently being conducted to find out if high-action video games are actually good for your ocular health. Meaning, of course, that when your parents said both, "Playing all those video games will ruin your vision!" and "Carrots are the best thing for improving your vision!," they were—GASP!—wrong! Well … maybe.

Apparently, the ability to discern between different shades of gray is an attribute in humans that is unable to be improved; however, it has recently come to the attention of scientists at the University of Rochester that playing video games that utilize high levels of action (like first-person shooters) actually improves the aforementioned attribute—meaning said video games actually improve your vision.

Now there is no reason to put down your controller and have fun whole time.
