How to Buy a Sleep Mask: Fit, Material, and Features to Look For

Forget those flimsy airline eye covers. Sleep masks have come a long way, and the market is filled with a myriad of options designed to help you fall asleep and maintain a good night’s rest. From luxurious silk masks to high-tech sleeping goggles, there’s a sleep mask for every need.

Sleep physician Lourdes DelRosso highlights the importance of quality sleep and how a simple intervention such as light-blocking masks can play a significant role. “Most research has been conducted in hospitals due to the noise and lights,” DelRosso says. “Providing sleep masks and earplugs to hospitalized patients has been studied and published, showing that patients experience deeper and more restful sleep. Just by covering their eyes, we can promote better production of melatonin and send better signals to our brain.”

Wearing sleep masks at night can also aid cognitive function, including memory, alertness, and episodic learning, according to a study from the Sleep Research Society.

And it’s not just the blackout effect of sleep masks that gives users a well-rested night. Sleep masks are a healthy sleep association, providing a relaxing and comforting experience that can help you wind down at night.

“We have touch receptors everywhere on our skin, including around the eyes,” certified sleep expert Annika Carroll says. “If we apply a little bit of light pressure there with this mask, it releases a hormone called oxytocin, often referred to as the love hormone. It promotes relaxation and comfort.”

What Shape and Fit Should I Consider?

Sleep mask fits aren’t universal, Carroll says: “I find that there’s a bit of trial and error in finding a mask that fits your face shape. There are rounder faces, and there are slimmer, longer faces.” Be sure to try on a new sleep mask before giving it a whirl; the mask should press gently against your face without feeling too tight, and there should be no gaps between the mask and your skin, especially around the nose area. Additionally, several sleep mask characteristics may affect how well it fits on your face.

Flat Masks

Flat sleep masks are the most traditional type you’ll see—they’re a flat piece of fabric that covers the eyes with no contouring. These types are generally lighter and more compact, making them easy to travel with.

Contoured Nose

A common problem with traditional slip-on sleep masks is the bridge of the nose lifting the mask, allowing light to seep in and defeating the purpose of wearing it. Many sleep masks today are designed with a contoured nose or without fabric around the nose to prevent any light from penetrating.

Eye Cups

Some eye masks are built like swim goggles: They feature two convex gaps that allow you to fully open and close your eyes beneath the mask without letting any light in. Eye cups are especially beneficial for people with sensitive eyes and for people who wear eyelash extensions.

Adjustability

Too loose, and the mask will fall off throughout the night. Too tight, and it could uncomfortably press against your eyes or snag your hair while you’re sleeping. Luckily, many sleep masks come with an adjustable strap so you can customize the fit.

When shopping for a sleep mask, examine the product to locate any clasps or adjustable closures. If you’re a back sleeper, you might prefer this piece on the side of your head. Stomach sleepers may find a clasp at the back more comfortable. For those who change positions frequently, consider an unobtrusive adjustment and/or closure mechanism like slim Velcro, a magnetic closure, or a slide buckle.
