Subconjunctival haemorrhage ?

My 2 year old is a very energetic fearless child and recently she injured herself some how I think she fell off her bed or hit herself in the face somehow, I was not there when it happened but I heard her fall and cry and now she has what appears to be a subconjunctival heamorrage ( a red spot in the white of her eye) is that spot in her eye now permanent, what can I do to help it heal. It does not seem to bother her at all....
