Your sleep mask is squashing your eyes all night.
Every flat mask makes you choose: press it into your eyes to actually block the light, or leave it loose and let light leak in around your nose.
Either way, you lose — pressure on your eyelids, flattened lashes, smeared eye cream, and a mask that ends up on the floor by 2am anyway.
That's not a design flaw. It's the only way a flat mask can work at all.
Meet the Zero-Pressure Blackout Chamber
The Halo isn't flat — it's contoured. Two deep, plush eye cups curve away from your eyelids, creating a private pocket of total darkness around each eye.
A padded nose bridge seals the #1 spot where light sneaks in. The result: 100% blackout, 0% contact.
Blink freely. Sleep on your side. Wake up with your lashes exactly where you left them.
