Experience Refreshing Mornings Without Eye Discomfort
The Eyeseals 4.0 is an innovative, soft, and hydrating sleep mask crafted to alleviate dry eyes as you sleep by sealing in moisture and minimizing tear evaporation. Developed by Eye Eco, this mask is perfect for individuals suffering from meibomian gland dysfunction, CPAP-related dryness, and nocturnal lagophthalmos. It operates passively while you’re asleep, requiring no external heat.
Understanding the Importance of Moisture: The Underlying Causes of Overnight Dry Eye
Many people erroneously perceive dry eyes as merely a result of insufficient tear production. However, the primary issue often lies in tear film instability, typically caused by inadequate oil secretion from the meibomian glands.
When these essential glands fail to function optimally, tears evaporate quickly—especially during the night when eyelid closure may be compromised, or environmental factors like CPAP machines and air conditioning enhance evaporation.
This leads to uncomfortable symptoms such as redness, grittiness, and blurred vision upon waking, significantly affecting your morning routine and overall comfort.

- Effectively trap natural humidity around the eyes
- Significantly reduce tear evaporation
- Shield against CPAP airflow or environmental dryness
- Prevent overnight irritation resulting from eyelid gaps (lagophthalmos)
