Hello kimberly;
welcome to HealthcareMagic
You should immediately visit a ER and better not to wait.Eye is a vital organ of a person and the loss of vision and pain can be due to
injury ;infection;increased intra-ocular pressure so it is better that she is examined by a Opthalmologist as early as possible so that there is minimal and reversible damage.
Take care;wish her a speedy recovery.
Thanks
