If you have an eye appointment soon and you wear contact lenses, you can sign up for a free trial pair of Focus Dailies. Just click on the link above and answer a few questions and you'll then be able to print a certificate for a free trial pair.
I've never tried printing certificates like these and taking them into my eye appointments. Have any of you? I'm just curious if they fulfill them easily or if they want to charge you extra money or give you some hassle. I suppose it depends upon your eye doctor but if any of you have had experience with these, I'd be interested to hear how it went for you.
