TranquilEyes XL Moist Heat Eye Mask delivers therapeutic warmth to relieve dry eye discomfort, styes, and meibomian gland dysfunction. The reusable mask is activated by soaking in hot water, then applied to closed eyes for a soothing spa-like treatment. The contoured silicone chamber holds heat for 10-15 minutes, allowing oils in the eyelid glands to soften and flow more freely. Regular warm compress therapy can significantly improve natural tear quality over time.
