Vampire Contact Lenses
One of the most popular special effects contact lenses at Halloween and at costume parties are vampire contact lenses. They are also very effective for use with stage costumes, so if acting is your thing, they could make a very effective addition to your thespian wardrobe. There again, if you simply want to scare off unwanted door to door salesmen, then vampire contact lenses can also be very effective, although it has to be said that many door to door salesmen are vampiric themselves, so may not be taken in.
Vampire contact lenses are not restricted for use by people with poor eyesight. When purchased over the counter, they do not have any prescription attached to them, so they will not affect your vision at all. That being said however, if you have an optical problem such as astigmatism, then these types of cosmetic contact lenses will have no effect, so if you need lenses such as these and you have poor eyesight, then you may need to get custom lenses made, which could prove to be expensive.
Vampire contact lenses are prepared differently from conventional cosmetic coloured contacts in that they are not tinted. Because of the effect required, the lenses are actually printed. Because of this, the effect that they produce can be quite stunning.
