Are there any eye drops to use on a two year old who has allergies?

There are a few brands on the market for children two years and older that are over-the-counter. However, it's important to note that any eye drops should only be used after consulting with a pediatric ophthalmologist or your doctor. Children's eyes can be particularly sensitive and react to even over-the-counter eye drops in ways that were unforeseen. Always get medical advice and/or consult with the pharmacist regarding any child's eye issues.
