How to Sharingan in Real Life
Have you ever wanted Sharingan powers like Kakashi Hatake from the series Naruto? Or would you prefer the abilities of King Bradley from Fullmetal Alchemist, or Ratio from Hamatora? All of these characters conceal a special eye that’s better than the one uncovered, and you can do it too. All you need is 30 minutes, something to cover one of your eyes, and a really cool name to give your unlocked ability (optional).
Begin by finding something to cover one of your eyes. An eye patch works best, but a skullcap or scarf pulled over one side works, too, as long as no light gets through. Just make sure you don’t put any pressure on your eye, else your vision will blur. (Remember when Sasuke’s vision started to blur???)
Leave your Sharingan eye covered for 30 minutes, while you do regular activity with the other eye. I recommend watching an episode of your favorite anime during this time, while imagining chakra gathering in your pupil.
After 30 minutes have passed, enter a dark room, say the name of your new jutsu, and see with your special eye. Throw in some hand seals for bonus cred.
It’s all made possible by a process in your eyes called Dark Adaptation. http://www.merriam-webster.com/dictionary/dark%20adaptation.
FYI: The reverse works just as well. The next time you wake in the middle of the night and need to make a trip to the kitchen or the restroom, cover one of your eyes with your hand before turning on any lights. You'll save the night vision (a.k.a. Sharingan) in that eye. The effect is trippy. Have fun!
