This sounds like physiological Anisocoria (simple Anisocoria). 20% of people have this mild eye disorder. There is nothing to worry about if this is the only symptom. One eye lighter than the other or a droopy eye lid may be signs of something much more serious called Horners Syndrome. Of course you should get the opinion of a licensed eye doctor.
yes but it should go away in less than a couple of hours.

i used a few allergy eye drops, mixed with contact solution to store my contacts last night. a bit after i put them in this morning i noted that my left pupil was quite a bit larger than my right. i read that it is possible for the allergy drops to be the culprit, but could it also cause my vision to be very slightly hazey in that eye as well?
Not likely that she's blind but that big of a difference in the size of the pupils is abnormal. Discuss it with your pediatrician, I would suggest you ask for a referral to a pediatric ophthalmologist. Be sure the ped Eye MD sees the child before any drops are put in the eye.
