Whether they are blue, red or even white contact lenses, a lot of that comes down to the rest of the outfit. A person wants to get this very unique look that can match with everything else. It is a very fun way of showing some originality without having to spend a lot of money.
Most contact options can be purchased online if the person wishes to. It is a very unique use for something like this, and most people are not going to use it on a daily basis. They are however capable of withstanding daily use as well.
