Streetlights, a partners reading lamp, summer sunrises at 5:40am. Whatever the light source, you have two real options: block the window or block your eyes. People get weirdly loyal to their pick, so heres the honest breakdown of both.

Blackout Curtains
$25 to $80 per window
VS
Sleep Mask
$10 to $40

Blackout Curtains

8.5
Darkens the whole room for everyone in it, nothing touching your face all night. They also knock down street noise a little and help with summer heat. Renters can use tension rods.
$25 to $80 per window

Sleep Mask

8.8
The most darkness per dollar, period. Total blackout for $10 to $40, works in hotels and on planes, and doesnt care how many windows your room has. You just have to be someone who can sleep with a thing on your face.

Blackout Curtains, Pros & Cons

What We Liked

  • The whole room gets dark, not just your eyeballs
  • Helps keep the room cooler in summer
  • Zero adjustment period, nothing to get used to

Worth Knowing

  • Light leaks around the edges unless you mount them wide and high
  • Costs add up fast with multiple windows
  • Youre in full darkness at 8am too, which cuts both ways

Sleep Mask, Pros & Cons

What We Liked

  • Cheapest path to total darkness
  • Contoured ones dont press on your eyes
  • One purchase covers home, hotels, planes, the in-laws guest room

Worth Knowing

  • Side sleepers need a contoured or low-profile mask or itll shift off by 2am
  • Cheap flat masks leak light at the nose, dont bother with those

Weve compared a bunch of both. The Manta Sleep Mask Pro is the one that made a mask convert out of a lifelong skeptic here, and our blackout sleep masks roundup has cheaper picks too. Going the window route instead? Our blackout curtains buyers guide covers sizing and mounting so you dont get the dreaded edge glow.

The Bottom Line

Get a contoured sleep mask first. Its ten to forty bucks to find out if total darkness fixes your sleep, and most people are surprised how much it does. Add blackout curtains later if the mask keeps sliding off or you share the room and want it dark for both of you. Plenty of light-sensitive sleepers end up with both and use the mask for travel.
