Yes: Yes. If they contain a"get the red out" vasoconstrictor component.
Dr. Duane Gels

No: Typically allergy eye drops contain antihistamines or saline. Should not noticably affect pupils. Even steroid Rx drops. Something else; ask your doctor. One pupil enlarged only? Go to ER.

Do allergy eye drops make the pupil larger?

Maybe: Certain eye drops, even over-the-counter eyedrops can affect the pupil usually making it larger. There are many good allergy drops that do not cause mydriasis (dilation of the pupil). Consult your ophthalmologist for recommendations.
