Documented eye effects of Allergy and Antihistamines

Pharmacological options include second-generation oral antihistamines such as cetirizine, loratadine and fexofenadine, which block the H1 histamine receptor with limited sedation; intranasal corticosteroids for rhinitis… Severe ocular events — sudden vision loss, persistent visual disturbances, retinal changes — are rare but require immediate evaluation.

Persistent blurred vision, double vision, severe light sensitivity or sudden vision loss while on Allergy and Antihistamines at 30mg, 60mg, 120mg, 180mg, 5mg is a stop-and-evaluate signal, not something to wait out.
