Cold Water: There are plenty of benefits of water, and one of them is to cure swollen eyelids. Washing the face in cold water can also help to reduce swelling. A cold compress of frozen peas is also beneficial to lessen puffy eyelids. The cooling sensation, be it of frozen peas or cold water, soothes the pain and itchiness. Cold compress constricts the blood vessels, which in turn decreases the blood circulation to the affected area. This helps to reduce the inflammation of the eyelids.
