Are Sleep Masks Worth It on a Plane?
Yes, a sleep mask is worth it on a plane if you plan to sleep and light wakes you up. It's one of the smallest, lightest things you can pack, and it fixes a problem no seat can: the cabin is almost never dark. But the free mask from the airline, or a cheap flat one, often isn't worth wearing. Here's why, and what to get instead.
Why light keeps you awake on a flight
On a plane, you don't control the light. Someone opens a window shade at noon. The crew turns the cabin lights up for a meal. The person next to you watches a bright movie a foot from your face. Even with your eyes shut, you can sense these changes, and each one can pull you out of light sleep.
A mask makes your own little dark room. That's the whole job. If it does that job, and stays comfortable for hours, it's worth packing.
When a sleep mask is worth it
- Long flights and red-eyes. On a flight of four hours or more, or an overnight flight, even a short nap helps when you land.
- Daytime flights. Bright sun through the windows is the hardest light to block. This is where a good mask matters most.
- You're a light sleeper. If a phone screen across the room wakes you at home, the cabin will too.
- You can't pick your seat. In the middle seat, you get your neighbors' screens and their window shade, and no say over either.
When it isn't
- Short flights. If you'll be awake for an hour, it's just one more thing in your bag.
- You never sleep sitting up. Some people simply can't. A mask can't change that.
- You bought a flat, thin mask. This is why many people decide masks "don't work." Here's what goes wrong.
Why cheap masks fail
Most cheap masks are a flat piece of fabric with an elastic band. They have three common problems:
- Light leaks at the nose. A flat mask can't follow the shape of your nose, so light comes in from below. This is the gap people complain about most.
- They press on your eyes. To block light, a flat mask has to sit right on your eyelids. After an hour, that pressure gets annoying, and you can't blink.
- They move when you lean. On a plane, your head ends up on the window, your shoulder or a pillow. A loose mask gets pushed up, and light floods in.
What makes a mask worth it
Look for these four things:
- Contoured eye cups. These are small domes that sit around your eyes instead of on them. They leave room to blink and keep pressure off your eyelids and lashes.
- A good seal at the nose. Some masks have a nose cutout. Others let you move the eye cups closer together or further apart to close the gap for your face.
- A slim side profile. If you sleep with your head turned, thick sides press into your face. Thin sides, or cups that lie flat at the temple, stay comfortable.
- An adjustable strap. It should be snug, not tight. A strap that sits above your ears is easier to wear when your head rests to one side.
Our top pick, the Manta Pro, checks all four. Its listing says it blocks all light even in daylight, its C-shaped eye cups sit flat against your temple, and both the cups and the strap adjust.
How to get the most from your mask
- Put it on early. Don't wait for the cabin to go dark. Once you want to sleep, put it on.
- Seal the nose first. Move the mask up or down until no light comes in at the bridge of your nose, then tighten the strap.
- Keep it within reach. Pack it in the seat pocket or a jacket pocket, not in the overhead bin.
- Pair it with support for your head. A mask blocks light, but it can't stop your head falling forward. A good neck pillow does that job. See our best travel pillows for airplanes.
- Add earplugs. Light and noise are the two big sleep breakers on a plane. Block both.
- Wash it after the trip. You wear it on your face for hours. Check the label first: some masks go in the machine, others are hand wash only.
The bottom line: yes, if the eye cups are contoured and it seals
A sleep mask is worth it if you want to sleep on a flight and you choose one with contoured eye cups, a good seal at the nose and a fit that stays put when you lean. A thin, flat mask is the one most likely to let you down. For five masks compared side by side, see our best sleep masks for airplanes.
