There is something about all black contact lenses that is truly creepy. They give a feeling of true evil and emptiness. Any demon costume or evil character will really freak people out with black contact lenses. It makes it seem like the monster has no soul. The bestselling lens is the Black Out Lenses and we highly recommend the Hellraiser Lenses as well. They have a red limbal ring around the black edge that gives a bloody / black look.
