Well played. I do the same but in Korea where the price for my brand is about $2 cheaper than JetLenses.
I have my vision checked in the contact store itself (for free) if I need it and then a proper eye exam during my annual physical check up (which is fully subsidized by my employer - a common practice, albeit at varying levels of support).
You need a prescription to buy contact lenses in the US?
Pills and such makes sense, but what can you do wrong with contacts, apart from having the wrong strength/astigmatism?
