It is a convenient way to order contact lenses without all the verification of prescription cr*p. It gets annoying when you are in your twenties, have little changes to your vision than already exists, and have to shell out money for another eye exam when your prescription hasnt even changed... HOWEVER:. If its color contacts you ordered from them, it could take up to over 2 weeks for them to backorder and ship them out and another 7-16 days to recieve them... thats a month to wait... normal contacts they ship out in a more timely manner
