Yeah you need to get a prescription for it.. if you do have it it is HIGHLY contagious so make sure you are washing your hands.. ALOT.. especially after touching your eye.. they will give you some drops, if you are in good with your doctor they might even just call it in for you. But seriously though.. it's very easy to spread to other people so wash your hands every chance to get and DONT TOUCH YOUR EYES, lol.. as much as you want to its not good...
