How to Choose a Silk Eye Mask: Fabric, Fit, Pressure and Light
A good silk eye mask should do four things well: use clearly specified silk, reduce the light reaching the eyes, fit around the nose and cheeks without large gaps, and stay secure without needing uncomfortable tension. Do not choose by momme alone. Momme describes silk fabric weight; it does not prove blackout performance. For side sleepers, edge and band comfort can matter as much as the front shape. Any “100% blackout” claim should be backed by product-specific testing.
The 30-second decision checklist
| Decision | What to look for | Do not assume |
|---|---|---|
| Fabric | Clear fibre composition, silk weight, quality specifications and textile-safety certification | That “silky” or “satin” automatically means mulberry silk |
| Light reduction | Coverage that follows your face, especially around the nose and sides; product-specific testing if a blackout percentage is claimed | That 22 momme, a dark colour or padding alone proves blackout |
| Fit | A shape that sits comfortably across the nose, temples and cheek area without large light gaps | That one contour fits every face |
| Pressure | A band and edge profile that stays comfortable in your usual sleep position | That tighter always means better, or that any mask is “pressure-free” for everyone |
Why light control matters
Light is not only something you notice while your eyes are open. International circadian-light experts recommend keeping the sleep environment as dark as practically possible because ocular light exposure influences circadian and sleep-related physiology. The CDC’s NIOSH guidance for shift workers similarly recommends a very dark bedroom and explicitly names an eye mask as one option when room-darkening measures are not enough.
Closed eyelids are not perfectly opaque either. Laboratory measurements show that visible light can pass through human eyelids, with transmission varying by wavelength and between people. The useful conclusion is modest: a physical light barrier at the eyes can be relevant when the room itself cannot be made sufficiently dark.
An eye mask is not a treatment for insomnia and cannot guarantee deeper or longer sleep. Think of it as a portable environmental tool—especially useful for daylight sleep, travel, late work schedules, hotel rooms or bedrooms with unavoidable light.
1. Fabric: start with composition, then momme
“Silk eye mask” should first answer a basic question: what is actually touching the skin? Siluxe specifies 100% mulberry silk, 22 momme and Grade 6A. Its current textile standard also includes OEKO-TEX® STANDARD 100 certification. OEKO-TEX describes STANDARD 100 as a certification for textiles tested for harmful substances, with stricter requirements as skin contact becomes more intensive.
Momme is useful, but only for what it actually measures: silk fabric weight. A 22-momme silk can feel substantial and luxurious, but 22 momme does not itself prove how much light a finished eye mask blocks. Light reduction depends on the complete construction—layers, filling if present, colour, face shape, nose area, side coverage and how the mask sits on the wearer. If you want the material explanation in detail, read what 22 momme means in silk.
2. Light reduction: judge the whole mask, not one specification
The most common shopping shortcut is also one of the least reliable: “higher momme equals blackout.” It does not. A dense silk shell can still leak light around the nose or sides; a softer construction may reduce more light on one face than another because it follows the contours better.
A practical test is simple. Put the mask on in a bright room without overtightening it. Look for the direction of remaining light: under the nose, at the temples, or through the body of the mask. If the issue is a nose gap, pulling the band tighter may only create more pressure without solving the geometry.
When a brand advertises a numerical blackout percentage or “100% blackout,” look for product-specific optical testing. Siluxe does not currently publish a validated blackout percentage for its eye mask, so this guide deliberately does not invent one.
3. Nose and coverage fit: geometry is personal
Faces are not standardised. Nose height, cheek shape and temple width change how a mask seals against ambient light. A lightly contoured shape can help follow the eye area, but contour alone does not prove universal fit, lash protection or zero pressure. If a mask leaves a large nose gap or needs aggressive tightening, the geometry—not the band tension—may be the problem.
4. Pressure and side sleeping: test your real sleep position
A mask that feels comfortable upright can feel different against a pillow. Side sleepers are often more sensitive to edge thickness, seams and the band at the side of the head. Test it in your usual position: it should stay secure without excessive tension or concentrated pressure at the temple, ear or nose.
Choose by your real situation
Day sleep or shift work
Prioritise light reduction and consistency. First darken the room as much as possible; then use an eye mask as the portable final layer. For a broader late-hours routine, see the five-minute night reset for people who finish work late.
Travel and hotels
Prioritise packability, a comfortable band and a surface you are happy to place against the eye area. A mask is useful because you cannot control every curtain, cabin or hotel light source. If you also gather your hair for travel, the Siluxe scrunchie size guide helps choose a low-profile or more generous silk tie.
Side sleeping
Prioritise edge and band comfort rather than chasing the thickest-looking mask. Test the mask on the pillow, not only in the mirror.

Frequently asked questions
Is 22 momme enough to make an eye mask blackout?
No. Momme measures silk fabric weight; it does not certify blackout performance. Finished light reduction depends on the entire construction and how the mask fits your face.
Is a contoured eye mask always better?
No. A contour can change how the mask sits around the eyes and nose, but face shape and personal comfort determine whether it is better for you.
What should side sleepers look for?
Pay close attention to edge thickness, seams and the band where the mask meets the pillow. Test it in your usual side-sleeping position before deciding.
Can an eye mask improve sleep?
A darker sleep environment is recommended by sleep and circadian experts, and an eye mask can help reduce light when the room cannot be made sufficiently dark. It cannot guarantee better sleep or treat insomnia.
Can I use an eye mask for daytime sleep?
Yes. CDC/NIOSH guidance specifically includes eye masks as one light-control option for people sleeping during the day or working night and evening shifts.
Does Siluxe claim 100% blackout?
No. Siluxe does not currently publish a product-specific optical test establishing a 100% or numerical blackout result.
What makes the Siluxe eye mask different from a generic “silky” mask?
Its material is specified: 100% mulberry silk, 22 momme, Grade 6A and OEKO-TEX® STANDARD 100, with a lightly contoured design and five current colours.
