The Types segmentation dissects the market into five pharmacologic sub‑classes: Antihistamines, Mast‑cell stabilizers, Combination antihistamine/mast‑cell stabilizers, Non‑steroidal anti‑inflammatory drugs (NSAIDs), and Corticosteroids. Antihistamines, such as olopatadine and azelastine, lead the market due to rapid symptom relief and a favorable safety profile, contributing the largest share of sales. Mast‑cell stabilizers (e.g., cromolyn sodium) provide prophylactic control, appealing to patients with mild, intermittent symptoms and supporting a niche but steady revenue stream. Combination agents merge immediate relief with preventive action, capturing a growing segment of patients seeking convenience and improved adherence. NSAIDs are employed for secondary inflammation control, representing a modest but strategic portion of the market, especially in post‑operative settings. Corticosteroids, while effective for severe inflammation, occupy a limited share because of safety concerns and restricted prescribing. Collectively, these sub‑types delineate the therapeutic breadth of the Eye Allergy Therapeutics market and inform product development and pricing strategies.
