Lumiero NightSeal 3D Sleep Mask
Blackout that follows every curve
Deep 3D eye cups help reduce direct eyelid pressure
Adjustable comfort for nights, naps, and travel
How does NightSeal block out light?
Its sculpted 3D shape follows the curves around your eyes while the contoured nose bridge helps close the gap where ordinary masks let light in. The result is a darker sleep space without having to darken the entire room.
Will it press on my eyes or lashes?
No. The deep 3D eye cups are designed to sit around your eyes instead of directly on them, leaving room for natural blinking, eyelid movement and lashes.
Is it comfortable for side sleepers?
Yes. The soft memory-foam contour and adjustable, hair-friendly strap help the mask stay comfortably in place without squeezing your head. Adjust it until the seal feels secure but relaxed.
How do I clean it, and what if it is not right for me?
Hand wash in water below 40°C with a mild detergent, then let it air dry naturally. Do not bleach, iron or machine wash. If NightSeal is not right for you, contact us within 60 days of delivery and we will help under our satisfaction guarantee.
THE NIGHTSEAL DIFFERENCE
Why flat masks fail after lights out
DEEP
Room around the eyes
Deep 3D eye cups create space around your eyes, helping protect your eyelids and lashes from direct pressure while you rest.
Deep 3D eye cups
FIT
Made to adjust
The flexible strap adjusts to your head for a secure, hair-friendly fit that works for nights, naps, flights and side sleep.

WHY NIGHTSEAL
Your room doesn't need to be dark
Streetlights through the curtains. A partner scrolling beside you. A bright hotel room or an early flight. Good sleep should not depend on perfect surroundings.
NightSeal creates a personal blackout space that moves with you. Its deep 3D contour blocks distracting light while leaving room for your eyes and lashes, so darkness finally feels as comfortable as it should.

The quality is excellent. It doesn't have any smell, it blocks out the light completely, the strap is adjustable, and it doesn't press on the eyes.

THE DIFFERENCE
Same room. A more comfortable way to block light.
A flat mask can shift, press on your eyelids and leak light around the nose. NightSeal's sculpted 3D contour creates room where you need it and a closer seal where light usually gets through.

Good
It's good.
Five-star rating
This buyer left a five-star rating without a written comment.
Very good quality
Very good quality. It feels nice.
No more light leaks
I bought a cheaper mask before, but light came through. This one doesn't, and the construction feels like it will last much longer.
The best blackout of the masks I tried
The mask is very comfortable and puts no pressure on my eyes. I can even open my eyes without discomfort. I tried other masks, but this is the only one that completely blacks out the light.
Fits well
Fits well. It feels comfortable and secure once adjusted.
Fits a larger head comfortably
Very comfortable. I have a 64 cm head, and at its largest adjustment it fits comfortably. Full blackout and no pressure on my eyes or eyelids.
Nice
Nice.
As described
It matches the product description. I would buy it again if I needed another one.
Good mask with one strap preference
Quite good. I only wish there were two straps, one above and one below the ears. The current strap can sit over my ears when I secure it.
Dark from the moment I put it on
I tried it on as soon as it arrived, and it was really dark. It feels like I'm going to sleep soundly.
Stays in place
I like it. The texture feels good, and it doesn't slip like other brands I've tried.
The band is adjustable
Before buying it, I wasn't sure it would fit my head, but the band is adjustable. The mask itself is a little bulky, but that wasn't a disappointment.
Loved it
Very good. I loved it.
Excellent for travel and meditation
Awesome mask. It provides excellent shading during the day and lets you keep your eyes open. It's especially good for meditation or sleeping on a plane.
Super
Super.
Quite comfortable
I found it quite comfortable.
Doesn't let light through
Very good. It doesn't let light through.
More comfortable than expected
It is much more comfortable than I expected.
Looks and feels good
It looks and feels good. I bought it for someone else, so I haven't personally slept in it, but visually it passes the test.
Soft and light-blocking
It arrived quickly and was just as described. It is very soft and does not let any light through.
Blocks every light source
It blocks literally every light source. Even if the sun were shining straight into the bedroom, I wouldn't notice.
Very good quality
Very good quality.
Very dark and comfortable
I tried it on right away. It was so dark that I couldn't see anything, but it was very comfortable. It also seems useful for outdoor activities and car camping.
Blocks even strong light
Honestly, it's everything I wanted from a sleep mask. It completely blocks light, even a direct beam from a strong flashlight. It's comfortable and doesn't move while I sleep.
Comfortable with full darkness
Comfortable and completely dark when I wear it.
No pressure on my eyes
It doesn't press on my eyes and gives complete darkness. It is a little less rigid than it looks in the pictures.
Soft with an adjustable strap
Total blackout and very soft. The adjustable head strap is useful because you can change the size.
I use it every night
Good product. I use it while sleeping every night.
Very nice
Very nice.
