No, I suggest you not to do that. As we all known, pink eye is a very common eye problem that could occurs at any stage. It is mainly caused by bacteria or virus that cannot be seen by natural eyes, especially when you use unclean hands to rub your eyes. At the same time, it is a contagious eye problem thus the bacteria or virus would be spread to others quickly. In your case, there would a group of people in a party with old friends and new faces. When you rubbing your pink eye even it is intentional, when you touch any object in the party, there is a high possibility for others to touch the same thing. And if they touch their eyes that would possible result in pink eye. In a word, you had better use some over the counter eye drops to cure pink eye and go to party when you are fine.
