1. Warm Compresses
Dry eye is caused by a lack of natural tears, which are composed of water and a much-needed oily substance. Over time, cells in the glands may harden, keeping the oil from getting into the tear film. Without that oil, the water in tears evaporates too quickly, leaving eyes feeling dry. A warm compress can help liquefy those plugs so the oil can flow into tears.
