Streetlights through the curtains, a partner reading on their phone, a charger LED that never switches off, a 6 a.m. sunrise in summer or a hotel room with blinds that do not quite close. Light finds its way into most bedrooms, and for light sleepers it is often the thing that turns a full night into a broken one. A good sleep mask is one of the cheapest fixes there is. So what is the best sleep mask? For most people, the MZOO 3D Contoured Sleep Mask is the one to buy first: soft memory foam, cups that keep pressure off your eyes, a shape that works for side sleepers, and a price that makes it an easy experiment. If you want the closest thing to total darkness and you mostly sleep on your back or stomach, get the Manta Sleep Mask. And if you want something light, slim and silky for travel or naps, the Alaska Bear Silk Sleep Mask is the budget favorite.
That is the quick answer. Below I go through what the research actually says about blocking light at night, how these masks compare, who each one suits, the fit problems that cause most returns, and the small checks worth doing before you buy. With U.S. clocks falling back on Sunday, November 1, holiday flights coming up and Black Friday on November 27, this is also the season when a lot of people pick up a mask for themselves or slip one into someone’s stocking.

Key Takeaways
- Best overall for most people: MZOO 3D Contoured Sleep Mask. Molded memory foam eye cups, thin angled sides for side sleeping, an adjustable strap and a pair of earplugs in the box. It is one of the best-selling sleep masks on Amazon, with more than 100,000 customer ratings.
- Best for maximum blackout: Manta Sleep Mask. Detachable eye cups you can slide and angle to fit your face, so it can seal out almost all light. Machine washable. Bulkier, and better for back and stomach sleepers.
- Best lightweight and travel pick: Alaska Bear Silk Sleep Mask. Mulberry silk on both sides with a thin foam insert around the eyes. Weighs almost nothing and packs flat, but lets in more light than the other two.
- For side sleepers who want Manta-level darkness: the Manta Pro Sleep Mask uses a slimmer strap and C-shaped cups designed for side sleeping, at a premium price.
- What the science says: in a Cardiff University study, young adults who wore an eye mask for a week did slightly better on a memory test and a reaction-time test than after a week with a mask that let light in. The effect was real but small.
- Fit matters more than brand: most light leaks come in around the nose. Check the nose shape, cup depth, strap length and how you sleep before you choose.

Do Sleep Masks Actually Help You Sleep Better?
Your body uses light as its main signal for day and night. When light reaches your eyes in the evening or while you sleep, it can nudge your internal clock and make sleep lighter or more broken. Darkness tells your body it is time to rest. A sleep mask is simply a way to make your own darkness when you cannot control the room.
There is decent evidence that this matters. In a study published in the journal SLEEP by researchers at Cardiff University, young adults aged 18 to 35 slept at home for a week wearing a light-blocking eye mask, and for another week wearing a control mask that did not block light. After the mask week, they learned word pairs a little better and reacted a little faster on an alertness test. In a second experiment with a sleep-tracking headband, the people whose learning improved most were the ones who got more deep, slow-wave sleep while wearing the mask. The researchers were careful to note the effects were modest, and the study was done on healthy young adults, so it does not prove a mask will transform anyone’s sleep. But it is a nice sign that blocking light does more than just feel cozy.
Light during sleep may matter for the body too. The U.S. National Heart, Lung, and Blood Institute highlighted a 2022 Northwestern study in which 20 healthy people in their 20s slept in a lab. Those who spent a night with overhead room lighting on had a higher heart rate and more insulin resistance the next morning than those who slept in dim light. It was a small study, but it is one more reason to keep your sleep space as dark as you reasonably can.
And sleep itself is worth protecting. The CDC says adults aged 18 to 60 need seven or more hours a night, and it lists a quiet, relaxing, cool bedroom among the habits that help. A mask will not fix stress, caffeine or an irregular schedule, but if light is what keeps waking you, it is the simplest and cheapest place to start.
The Best Sleep Masks in 2026: Detailed Reviews
1. MZOO 3D Contoured Sleep Mask: Best Overall for Most People
The MZOO Sleep Mask is the mask you see in a lot of carry-on bags, and for good reason. It ranks as the top seller in Amazon’s sleep mask category, with more than 100,000 customer ratings, and it gets the basics right for most faces. The body is low-rebound memory foam shaped into two eye cups, so the fabric sits on your brow and cheekbones instead of pressing on your eyelids. MZOO lists the cups at 13 mm deep, enough for most people to blink freely, and adds 22 mm of padding at the nose to stop light sneaking in from below.
The detail side sleepers will like is the shape of the edges. The sides are thin and angled, so when you turn your head onto the pillow there is no thick block of foam digging into your temple. The strap is wide, soft and adjusts with a sliding buckle rather than hook-and-loop, which means it does not catch your hair. MZOO lists it at 19 to 28 inches, and TechGearLab’s testers measured roughly 18 to 26 inches, so it should fit most adult heads either way. In the box you also get a pair of foam earplugs and a travel pouch, which makes it a ready-made gift.
It is not perfect. In TechGearLab’s testing, the cups were not deep enough to stop long lashes brushing the fabric, and a tester with a narrow nose saw light leaking in around the nose in bright midday sun. In a normal dark bedroom that leak was not an issue. The fabric can also darken over time from skin oils, and it is hand wash only, so plan on a quick rinse every week or two.
- Pros: comfortable contoured foam that keeps pressure off your eyes; slim sides for side sleepers; strap that does not snag hair; earplugs and pouch included; easy, low-cost first mask.
- Cons: can leak light around narrow noses in very bright rooms; long lashes may touch the cups; hand wash only.
- Best for: side and combination sleepers, first-time mask users, travelers, and anyone who wants a dependable mask without overthinking it.
2. Manta Sleep Mask: Best for Maximum Blackout
If even a thin line of light bothers you, the Manta Sleep Mask is built for you. Instead of one fixed shape, it uses two separate eye cups that attach to the strap with a soft hook-and-loop closure. You slide each cup to sit right over your eye socket and angle it to match your face, so the seal is shaped around you rather than around an average face. Manta’s own product page promises a full blackout and backs it with a 60-day money-back guarantee if you buy direct.
Independent testing supports most of that claim. TechGearLab ranked the Manta first in its sleep mask lineup, and it was the top performer in their bright LED flashlight test. Testers could still pick up a faint reddish glow with a flashlight shone right at it, but in everyday conditions like midday sun through a window or a bedside lamp, they found near-complete darkness was achievable. The cups are deep and hollow, so most people can blink without their lashes touching anything, and the whole mask, cups included, goes in the washing machine on cold in a mesh bag.
The trade-offs come from that same design. It is noticeably bulkier than a flat mask, so it takes up more space in a bag. Getting the cup position right can take a few nights of small adjustments, especially if you have a smaller face. And while some people sleep on their side in it, the cups stick out enough that many side sleepers feel them press into the pillow. Manta’s answer is the Manta Pro, which has C-shaped cups and a slimmer, angled strap designed for side sleeping, but it costs more than twice as much as the original.
- Pros: the closest thing to true darkness of any mask here; fully adjustable cup position and angle; zero pressure on eyes and lashes; machine washable; long-lasting build.
- Cons: bulky for travel; setup takes trial and error; not ideal for side sleepers; costs more than the other two picks.
- Best for: night-shift workers and daytime sleepers, people in bright city apartments, back and stomach sleepers, and anyone who has tried cheaper masks and still sees light.
A quick note if you also use a sunrise alarm: a blackout mask will block the very light that is supposed to wake you. Our guide to the best sunrise alarm clocks covers this, but in short, you can take the mask off when you wake in the night or before dawn, or rely on the alarm sound instead.
3. Alaska Bear Silk Sleep Mask: Best Lightweight and Travel Pick
Not everyone wants a molded foam mask on their face. If you find contoured masks hot, bulky or claustrophobic, the Alaska Bear Silk Sleep Mask is the classic alternative. It is made of mulberry silk on both sides, with a thin layer of foam stitched in around the eye area to give a little room for your eyes, and a single adjustable elastic strap that is latex-free. There is no piping or rough edging, so it is less likely to leave lines on your face in the morning. It weighs well under an ounce, packs flat into the included pouch and is easy to keep in a bag, a desk drawer or a seat pocket.
It is one of the longest-running popular masks on Amazon, with tens of thousands of ratings, and Wirecutter includes an Alaska Bear silk mask among its picks, noting it fits almost any face thanks to its flat design and adjustable strap, though it does put some pressure on the eyes. That sums it up well. Because it is soft and flat, it works in any sleeping position, including face-down, and it feels lovely on sensitive skin. But because it is soft and flat, it cannot seal as tightly as a molded mask, and some light can creep in around the nose. If you want a better seal, Alaska Bear also sells versions with a small fabric nose flap.
- Pros: very light and slim; silk on both sides feels smooth and cool; works in any sleep position; latex-free strap; great value.
- Cons: not a full blackout; some pressure on the eyelids; delicate fabric needs gentle washing.
- Best for: frequent flyers, afternoon nappers, stomach sleepers, people with sensitive skin, and anyone who finds foam masks too bulky.
Contoured vs Flat vs Adjustable Cups: Which Type Is Right for You?
Most sleep masks fall into one of three styles, and choosing the right style matters more than choosing the right brand.
Contoured foam masks
These have molded cups that arch over your eyes, like the MZOO. They give your eyes room to blink, avoid smudging eye cream, and usually block light well. They are a good default for most people. Their weak spot is a fixed shape: if your nose bridge or cheekbones are very different from the mold, you get gaps.
Flat silk or fabric masks
These are simple padded shapes, like the Alaska Bear. They are the lightest, the easiest to pack and the most comfortable for stomach sleepers. The downside is that they rest on your eyelids and seal less tightly.
Adjustable-cup masks
These use separate cups you position yourself, like the Manta. They offer the best seal and the most custom fit, but they are bulkier and take some setup. If you have struggled with light leaks in every other mask, this is the style to try.
How to Choose a Sleep Mask: What to Check Before You Buy
How you sleep
This is the big one. Side sleepers need thin, angled sides and a strap that does not have a hard buckle sitting right where your head meets the pillow. Back sleepers can use almost anything. Stomach sleepers usually do best with a flat, soft mask.
Nose fit and light leaks
Light most often gets in at the nose. Look for a mask with a raised nose bridge, extra padding under the eyes, or a fabric nose flap. If you have a narrow or low nose bridge, adjustable cups or a flap will usually seal better than a fixed foam shape.
Eye pressure and lashes
If you wear lash extensions, use eye cream at night, or simply hate the feeling of fabric on your eyelids, choose deep contoured or hollow cups. Flat masks are fine for many people, but they do rest on your eyes.
Strap and head size
Check the strap range in the listing, especially if you have a larger head, thick hair or wear your hair up at night. Hook-and-loop straps adjust easily but can snag hair if they are not the snag-free kind. Buckle straps avoid that but can be felt on the side of the head.
Heat and breathability
Foam masks can feel warm in summer or in a heated room. Silk and ventilated designs run cooler. If you tend to sleep hot, start with a lighter mask.
Washing and hygiene
A mask sits on your face all night, so it needs washing. Machine-washable masks like the Manta are easy. Hand-wash ones like the MZOO need a little more effort. Whatever you buy, wash it before first use and every week or two after that.
How Much Should You Spend on a Sleep Mask?
Prices change often, especially around Black Friday, so check the current price on each product page. As a rough guide, the Alaska Bear and MZOO sit at the low end of the market, while the Manta original costs a bit more and the Manta Pro sits at the premium end. The good news is that there is no subscription, app or upkeep with any of them. Even the premium choice costs a fraction of what many people spend on blackout curtains, a new mattress or a sleep app over a year.
If you are not sure whether masks are for you at all, start with one of the cheaper picks. If you love the darkness but notice light leaks, that is when it makes sense to step up to adjustable cups.
Getting Used to Wearing a Sleep Mask
Many people pull a mask off half asleep during the first few nights. That is normal. In the Cardiff study, participants had five nights to get used to their masks before any testing began. A few things help:
- Start loose. A strap that is too tight is the most common reason people give up. Tighten it just enough that the mask stays in place when you turn your head.
- Put it on last. Read, stretch or listen to something calming first, then slip the mask on when you are ready to close your eyes.
- Pair it with sound control. Light and noise often come together. Earplugs or a fan can help, and our guides to the best earplugs for sleeping and the best white noise machines for sleep cover both.
- Use it for naps first. A 20-minute afternoon rest is a low-pressure way to get used to the feel.
- Build a calm wind-down. A cool room, low lights and something soothing, such as a weighted blanket, help the mask become part of a routine rather than a gadget.
- Give it a week. If after a week it still bothers you, try a different style instead of giving up on masks altogether.
Who Should Not Rely on a Sleep Mask Alone
A mask is a comfort tool, not a treatment. If you snore loudly, stop breathing during sleep, wake up exhausted after a full night, or have trouble sleeping most nights for weeks, talk to a doctor. Conditions like insomnia and sleep apnea need proper care, and the CDC recommends speaking to your healthcare provider if you regularly have problems sleeping. Also, if you have an eye condition or recent eye surgery, ask your eye doctor before wearing anything over your eyes at night. Parents should be careful with masks and straps around babies and young children.
Frequently Asked Questions
What is the best sleep mask for side sleepers?
The MZOO 3D Contoured Sleep Mask is the best value for side sleepers because of its thin, angled sides and soft strap. If you want the darkest possible seal while sleeping on your side and do not mind paying more, the Manta Pro is designed specifically for that.
Which sleep mask blocks the most light?
Of the masks here, the Manta Sleep Mask blocks the most light because you can position each eye cup to fit your face. In TechGearLab’s testing it performed best in a bright flashlight test, though a faint glow could still be seen in that extreme case.
Is it safe to wear a sleep mask every night?
For most healthy adults, yes. Keep the strap comfortable rather than tight, choose a mask that does not press hard on your eyes, and wash it regularly. If you have an eye condition, check with your eye doctor first.
Do sleep masks really improve sleep?
They can help when light is what disturbs you. A Cardiff University study found people did slightly better on memory and alertness tests after a week of sleeping in a light-blocking mask, linked to more deep sleep. The benefit was modest, so think of a mask as one helpful piece of a good sleep routine.
Silk or foam: which sleep mask material is better?
Foam contoured masks usually block more light and keep pressure off your eyes. Silk masks are lighter, cooler and gentler on skin, and they pack flatter for travel. Choose foam for darkness and silk for comfort and portability.
How often should I wash my sleep mask?
Wash it before first use and then every week or two, more often if you use face creams or sweat at night. Follow the care label: the Manta is machine washable on cold, while the MZOO and Alaska Bear should be washed gently by hand in cool or lukewarm water.
Is a sleep mask a good gift?
Yes. It is useful, affordable and suits almost anyone, from new parents and night-shift nurses to students and frequent travelers. The MZOO even comes boxed with earplugs and a pouch, which makes it an easy stocking stuffer.
Conclusion
Darkness is one of the simplest gifts you can give your sleep, and a good mask brings it with you wherever you go. For most people, the MZOO 3D Contoured Sleep Mask is the right first buy: comfortable, side-sleeper friendly and easy on the wallet. If you need the deepest darkness possible, especially for daytime sleep, choose the Manta Sleep Mask. And if you want something soft, slim and silky for travel and naps, pick the Alaska Bear Silk Sleep Mask. Start with a loose strap, give it a week, and pair it with a calm wind-down.
