Well, in my opinion, you are not supposed to have foundation when you suffer from pink eye. Generally speaking, pink eye is a kind of eye infection, which can be just caused by viruses, bacteria, irritants, allergies. In common, there are some symptoms which can just occur. For example, one of your eyes, or both of your eyes will be red, itchy, even burning. And at this time, if you wear foundation which is made from chemical material, it will just make your situation more serious. So just give up it. Also, you should keep your eyes far from infection resource. By the way, you can just try rose water.
