I get mine at the beauty supply store in Oakland. I forget the name...It was a yellow and blue building on Telegraph and I think 27th st. $20 bucks. No prescription needed. I suggest you get the brand in the blue box (they only have two brands for regular lenses). The blue box ones are more straightforward for the color you choose. The ones in the purple box tend to add a more "realistic" look that I'm not terribly sold on. The one pair of light blue color contacts I bought from the purple box brand had a bit of yellow around the outside of the pupil to simulate what some people with real blue eyes, have (like my best friend). I hope that made sense. Gomen!
