What is called tattoo open eyes?

Can be said to be a tradition, right, is a tattoo of small animals or characters, if their eyes are open, it is called tattoo open eyes.

Science:

Generally speaking, tattoos can not open the eyes, will make the hostility too heavy.

Generally tattoos are not recommended to open the eyes, no matter what animal, or human patterns. It's sort of a tradition to believe that eye possession can invoke its spirit, thus making it easy for the tattooed person to encounter something inexplicable or psychic.

But it's all superstitious in there, so it's better to believe in science and think for yourself.
