Usually, when you go in for a fitting they give you a “sample pair” to wear, to make sure your eyes take to the contacts. If all goes well, you make a return appointment to pick the rest of them up. The best thing to do on Saturday is ask your doctor if you should drive with them in. They may say it’s okay, or they may say it’s not a good idea since this will be your very first time wearing them. Do you currently wear glasses? Or are you completely new to the world of contacts and glasses? If so, I suggest buying a pair of glasses along with your contacts – which can be done the same day as the appointment. That way you can wear the glasses while you drive and just put the contacts in once you get to L.A.
