Eyeseals 4.0 Hydrating Sleep Mask: Overnight Relief for Dry, Irritated Eyes
Wake up without the burn, grit, or blur
Eyeseals 4.0 is a soft, hydrating sleep mask designed to relieve dry eyes overnight by locking in moisture and reducing tear evaporation. Developed by Eye Eco, it’s ideal for people with meibomian gland dysfunction, CPAP-related dryness, and nocturnal lagophthalmos. It requires no external heat and works passively while you sleep.
Why Moisture Matters: The Real Cause of Overnight Dry Eye
Dry eyes are often misunderstood as simply “not enough tears.” But in reality, most cases are caused by tear film instability, usually due to a lack of oil from the meibomian glands.
When these glands underperform, your tears evaporate too quickly — especially overnight when eyelid closure weakens or airflow (like CPAP or air-con) increases evaporation.
The result? Red, gritty, or blurry vision when you wake up.
What Is the Eyeseals 4.0 Hydrating Sleep Mask?
The Eyeseals 4.0 is a medical-grade sleep mask that creates a moisture-rich microenvironment around the eyes while you rest. Unlike traditional heat masks that require warming, this mask works passively, using your body heat and its patented design to:
- Trap natural humidity around the eyes
- Reduce tear evaporation
- Protect against CPAP airflow or ambient dryness
- Prevent overnight irritation from eyelid gaps (lagophthalmos)
Its anatomical shape gently seals the area around your eyes without pressure, making it safe for extended overnight wear. Explore more dry eye solutions here.
