Images like crosses, angels and portraits of religious figures serve as physical representations of faith. Get an Eye of God tattoo to show a belief in a higher power. The Eye of God, also known as the Eye of Providence or the All-Seeing Eye, represents the idea of a supreme being watching over the world. The common image is of an eye encased in a triangle. Get this image as a tattoo to show your belief in a higher being or as a reference to secret societies and Freemasonry, which this image is often connected to.
While it's dangerous to tattoo an actual eye, you can get a tattoo of eyes on your eyelids to create the illusion that your eyes are always open. This is a good tattoo to get if you want to scare people or give yourself a set of eyes you've always wanted. For example, you could get an eyelid tattoo featuring cartoon-like eyes or blue eyes if your eyes are brown.
Eyes are fitting tattoo images because, like tattoos, they can be very expressive. You can tell a lot about someone's feelings by looking at their eyes. Get a tattoo of a set of eyes to express your personal and/or favorite emotional state. If you tend to be a sad person, get a set of eyes with tears dripping off of them.
