There are a few quick things you can do to alleviate chemosis. Applying a cold compress, such as a wet cloth or ice pack, gently on the affected eye can help. Avoid irritants that could worsen the swelling, such as smoke or strong chemicals. Use lubricating eye drops, specifically artificial tears, to soothe the eye and reduce irritation. If symptoms persist or worsen, see your eye doctor for a proper diagnosis and treatment.
