The Big Chill. Tired eyes wake up fast when you give them a dose of cold. If youâre feeling brave and want the quickest relief, dunk your face into a large bowl filled with ice water. For a less bracing experience, soak a washcloth in cold water, then lie down with the cloth over your eyes for 10 to 15 minutes.
A warm compress can help relax the muscles around your eyes. This can help relieve that tired feeling. To make a simple compress, moisten a clean washcloth or a few clean paper towels with warm (but not hot) water. Lay the cloth over your eyes for a few minutes until you feel soothed. You can also make a warm compress with a tea bag. Steep the bag in some warm water, then squeeze the excess from the tea bag.
