5. Whitish or yellowish discharge
In addition to excessive wateriness, you might also notice that your eyes are producing a discharge that is whitish or yellowish in color. Discharge is a normal function of the eyes that is produced by the tear film. Known as rheum, this watery discharge is produced by the conjunctiva and is vital for healthy eyes, as it keeps them lubricated. Since the pink eye inflames the conjunctiva, the discharge can be produced in excess and is highly noticeable.
It can appear as a whitish or yellowish film, and in some cases, it might even look greenish in color. It can gloppy in nature and cause crusting on the affected eye, which could seal the lids together and make it difficult to open the eye. You will likely notice this crusting after waking up, but you can see the discharge being produced while you are awake, too.
