Well, in my opinion, it is possible to have pink eye because of throat infection. So if you have pink eyes, you should try to find out the causes from other ways. Generally speaking, there are many factors which can just lead to pink eyes. For example, viruses, bacteria, allergies, a chemical splash in the eyes can just be the reasons. But on the other hand, there is no evidence which has shown that throat infection can cause it. When you have pink eyes, you need to have some cold compresses to relieve the symptoms. Also, just try to find the causes and avoid it.
