3D sleep mask vs flat sleep mask
A flat sleep mask is a strip of fabric that lies right on your eyes. A 3D mask has two moulded cups, one over each eye, so the mask touches your face round the eye socket and the part over your eye sits off it.
That one difference decides most of what follows.
Side by side
| 3D sleep mask | Flat sleep mask | |
|---|---|---|
| On your eyes | Cups sit off your eyes and lashes | Fabric lies on your eyelids |
| Blinking | You can blink with it on | Your lids push against the fabric |
| Lash extensions and makeup | Nothing presses on them | Presses on lashes and rubs whatever's on your lids |
| Side sleeping | The cups are thicker, so it's more mask between your face and the pillow | Thin, so the pillow side lies flatter |
| Packing | Holds its shape, takes a bit more room | Folds up to nothing |
When a 3D mask is the better pick
You don't like anything touching your eyes. You have lash extensions, or you sleep with makeup on after a late shift. You wake up and open your eyes under the mask before you want to get up. Or you've tried flat masks and kept pushing them up off your eyes in the night.
Our Eye Mask is a 3D mask with moulded cups about 20 mm deep. A slider on the elastic band sets how tight it sits on your head. It's feather light at 26 g and it's C$13.99, in black, purple or pink.
When a flat mask is the better pick
You sleep face down into the pillow most of the night, where a thin mask lies flatter. Or the mask is going in a jacket pocket and you want it to fold as small as it can.
Either way
A mask is for when you can't fix the room, a plane, a hotel, a partner reading with the lamp on. For your own bedroom, how to make a bedroom pitch black covers the window and the gaps, and how to sleep on a plane covers the mask on the road. The mask is in our blackout collection and our travel sleep collection.
