If you order from lens.com--the site that not only sponsors Lens 101 but also has some of the lowest prices on the Internet--they have Acuvue 2 Colours - Enhancers starting at just $28 for a box of six lenses. Don't forget that you'll probably need a box for each eye, unless you have the exact same prescription in both eyes.

Is that expensive? You tell me. I think it's a great price.

As for your second question "Will it be economical than the normal contacts?" I'm not sure what you're asking.
