My kid where playing one got hurt herd the cry went to see what happen my 1year old girl got hurt pick her up calmed her down no cuts bumps or bruses so I lad her down for bed then I notice a red dot in her eye I've seen them in adults but not kids not sure how they get them

There are many different causes for this, some that are nothing to worry about, others that could be very serious.

I would suggest taking your child to the doctor.
