Contact lenses, even decorative/cosmetic ones without any power, are prescription devices. They must be fit by an eye care professional to ensure they center appropriately, move ~0.5-1.0 mm on the cornea with every blink, and extend far enough onto the white part of the eye to prevent damage/irritation. There is actually a federal law that states you must have valid contact lens prescription from a doctor to obtain any contact lens. Some contact lens outlets choose not to abide by the law, deciding the profit outweighs the risk of being involved in litigation. Also, these outlets that choose to disobey the law sometimes sell fraudulent merchandise...you may think you are getting a reputable brand, but your have to instill trust in your supplier. Doctors deal either directly with the contact lens company or wholesale providers, so you can trust their products.
