Six Engineering Choices That Make The Daily Warm-Compress Routine Stick
3-Temperature Precision Heat
113°F for daily fatigue, 131°F for the meibomian-gland session, 143°F for deep tension. One button cycles all three.
NTC Chip Sustained Heat
Negative-temperature-coefficient regulation holds your setpoint within ±2°C for the whole 15 minutes — no peak-then-drop curve like microwave masks.
Cordless USB-C Freedom
1000mAh internal battery, 4-5 sessions per 2-hour USB-C charge. Use it at your desk, on a flight, lying on your side in bed — no outlet, no cord wrap.
Sealed Light-Blocking Geometry
Contoured nose-bridge and edge seal block 100% of ambient light. The warm-compress device doubles as a complete-blackout sleep mask.

Frequently Asked Questions
How long does the heat actually stay at the setpoint?
How long does the heat actually stay at the setpoint?
The NTC regulator holds your selected temperature (113°F, 131°F, or 143°F) within ±2°C for the full 15-minute session. Unlike microwave-activated beaded masks, there is no peak-then-drop curve — heat stays sustained until auto-off.
Which temperature setting do I use for dry eye and meibomian gland dysfunction?
Which temperature setting do I use for dry eye and meibomian gland dysfunction?
131°F (55°C) is the middle setting most users reach for during daily warm-compress sessions targeting evaporative dry eye and MGD. 113°F is gentler for eye fatigue. 143°F is for deeper tension. Start lower, step up as your eyelids tolerate.
How long does the battery last between charges?
How long does the battery last between charges?
Real-world: 4-5 full 15-minute sessions per single 2-hour charge. That is roughly 75 minutes of total heated time. Twice-a-day users plug in via USB-C every 2-3 days. The Type-C port works with any standard phone or laptop cable.
Can I sleep with it on overnight?
Can I sleep with it on overnight?
The heat auto-shuts off at 15 minutes, so falling asleep with it on is fine — the device cools, you keep the blackout sleep-mask benefit. Running heat continuously overnight is not recommended; the 15-minute window is intentional.
Will it fit my face if I wear glasses or have a wider/narrower head?
Will it fit my face if I wear glasses or have a wider/narrower head?
The elastic strap adjusts across a wide head range and the contoured shell fits most adult faces without nose-bridge pressure. Remove glasses before use. The 85g weight means no pressure marks after a 15-minute session.
Is it safe for contact lens wearers?
Is it safe for contact lens wearers?
Remove your contacts before each session. Heat plus contact lenses traps moisture against the eye and may affect lens material. With contacts out, the warm compress lets meibomian glands secrete the lipid layer your tear film needs.
How do I clean it?
How do I clean it?
The satin-silk inner cover detaches and goes in the washing machine on cold, gentle cycle. Air dry. Weekly washing keeps the eye-area surface clean. The heating shell is IPX4 splash-resistant — wipe with a damp cloth, never submerge.
Does it actually help with tension headaches and ocular migraines?
Does it actually help with tension headaches and ocular migraines?
The 143°F deep-heat setting and sealed blackout shell are what most migraine-prone users reach for at the start of an aura. Heat dilates orbital vessels, darkness removes light triggers. It is a relief tool, not a medical treatment.
