Eye allergies can be an annoying complication of seasonal changes but there’s important information that can help you treat those symptoms. An allergic reaction affecting the conjunctiva, the clear layer overlying the eye, is commonly referred to as allergic conjunctivitis. There are several subtypes/subdivisions of allergic conjunctivitis, with the most common being seasonal allergic conjunctivitis (SAC) and perennial allergic conjunctivitis (PAC). Both SAC and PAC are triggered by an immune reaction involving a particular allergen.
Common allergens include: pollen, grass, weeds, dust, and pet dander.
