As if these tattoos weren't already strange enough, some folks like to take it a step further and compliment their ink with some blood, a freaky hand or other macabre ideas.
As you can see the back and back of the head is two of the most popular locations for eye tattoos, and i can see why, they look beyond creepy on those areas of the body.
Another rather common tattoo design is the ancient Egyptian symbol of protection and royal power, known as the eye of horus. Said to bring fourth protection and prosperity among other things.
One of the most underrated tattoo ideas has to be the feline eyes, and unlike humans, feline peepers are very attractive and quite sexy, perhaps an excellent idea for the ladies.
