Does Pearle Vision, Lenscrafters or Iris sell non prescription colored contacts?
Pearle Vision and Iris both sell contact lenses directly; Lenscrafters doesn’t (at least around here) but their independent doctors of optometry usually do. You may need an eye exam to verify that you don’t need a prescription and/or some form of training or examination for the lenses themselves. As far as the colours go, there are different kinds of coloured lenses meant for light eyes or dark eyes or whatever. Basically there are completely opaque ones to totally change your eye colour, and more translucent ones to emphasize a different colour or change things slightly. Most places have at least a catalogue of colours if not sample lenses for you to see.
