Hay fever - Eye Drops
Allergic conjunctivitis causes itchy, red, watery eyes during hayfever season. Antihistamine eye drops can target these eye symptoms directly
About hay fever - eye drops
When pollen contacts the surface of the eye, it triggers a local allergic reaction similar to that in the nose, causing swelling of the conjunctiva (the membrane covering the white of the eye and inner eyelid) and increased tear production. It often occurs alongside other hayfever symptoms but can also happen on its own
Treatments
Symptoms
• Itchy, red eyes
• Watering or excessive tearing
• Swollen or puffy eyelids
• A gritty or burning sensation
• Sensitivity to light
• Symptoms often worse after exposure to pollen, dust, or rubbing the eyes
Diagnosis
Allergic conjunctivitis is usually diagnosed from typical symptoms and their link to allergen exposure or hayfever season. Persistent, painful or one-sided symptoms, or reduced vision, need assessment to rule out an infection or other eye condition
Treatment
Antihistamine eye drops (such as those containing azelastine or ketotifen) relieve itching and redness quickly by blocking the local allergic reaction. Sodium cromoglicate drops can help prevent symptoms if used regularly before exposure. Cool compresses and lubricating drops offer additional relief
Prevention and self-care
• Avoid rubbing the eyes, as this worsens irritation
• Wear wraparound sunglasses when outdoors
• Use eye drops before high pollen exposure if prone to symptoms
• Wash hands before touching the eyes
• Rinse eyes with cool water after outdoor exposure
• Keep windows closed during high pollen counts
