Seasonal allergic conjunctivitis (SAC) is an allergic reaction that affects the eyes, causing inflammation and irritation of the conjunctiva, which is the thin layer of tissue that lines the inside of the eyelids and covers the white part of the eye. It is a common type of allergic conjunctivitis that is typically caused by an allergic reaction to airborne allergens such as pollen, mold spores, and dust mites.
Symptoms of seasonal allergic conjunctivitis may include redness, itching, tearing, burning, and swelling of the eyelids. It can also cause sensitivity to light, blurred vision, and a gritty or sandy sensation in the eyes. The symptoms of SAC usually occur during certain times of the year when there is an increase in the level of the allergen in the environment, such as during the spring and fall.
Treatment for seasonal allergic conjunctivitis may include over-the-counter or prescription eye drops, antihistamines, and other medications to relieve the symptoms. In some cases, avoiding exposure to the allergen or wearing protective eyewear can also help to prevent or reduce the severity of symptoms.
