An eye sleeping mask is a soft, lightweight cover designed to block out light and create a dark, calming environment for better sleep. Made with gentle fabric like silk, cotton, or memory foam, it rests comfortably over the eyes without causing pressure. Perfect for use at night, while traveling, or during daytime naps, it helps improve relaxation, reduce eye strain, and promote deeper, more restful sleep. Some eye masks also come with cooling gel inserts or aromatherapy features for added comfort and stress relief.
