Sounds like conjunctivitis. You can bathe the eye with a cotton wool pad dipped in warm water with a drop of baby shampoo in it, or you can go to the chemist and get some anti-bacterial drops (which, if your DC is anything like mine, she'll refuse to co-operate with or hold still while you're trying to drop them in). Your call. They both work IME.
The gp (last time she had this) told me to just get eye drops over the counter. The chemist reccommend soothing dry eye drops so used that before bed tonight.
juneau isnt conjunctivitus when the eye is pink or red? Her eye isnt at all not even swollen but is producing lots of green gunk. This always seems to be related to a bad cold but worried it could be conjunctivitus in which case would she need medicated drops?
Little monster my DS had the same thing it was confirmed at conjunctivitis I would make fresh cotton balls up to clean the eyes with cooled boiled water and head on fucithalmic (which didn't Work) then went onto the drops and it got so much better within 3 days.
