Allergies are often due to a reaction to pollen or other air-borne allergen and irritants. Both seasonal and chronic allergies cause symptoms such as coughing, sneezing, and runny nose. Many remedies to allergies involve the use of allergy medication, or anti-histamine. These medications have side effects that typically cause dry eye symptoms to begin or worsen.

 

Ocular allergies can either be asymptomatic, or include itching, watering, redness, and discomfort in mild forms. If ocular allergies are more severe, they can often cause inflammation and swelling of the conjunctiva.
