They absolutely do not hurt if you wear them just for fun and not wear it for days each time. I always use colored contacts for Halloween, theatrical or novelty uses. Nowadays, neon glow-in-the-dark UV lenses or special-effect lenses are cool. It is worth mentioning that the lenses need to be properly prescribed and cared for, your practitioner will give you the to-do list. In US , you may not legally buy a novelty contact with medical devices without a contact lens prescription. The legitimate source for purchasing are absolutely needed, especially when you decided to buy them on the online stores. The proper way to wear the lenses is also important, like washing your hand thoroughly, keeping your nail short and storing the lenses by soaking in its special liquid.
