I recently gave up on making my room blackout dark when I sleep. Instead, I wear sleep masks. They're not perfect: they slip a little as I sleep, and the cheap ones wear out fast. But it's still not expensive ($10 for 3), and the masks themselves block all light. I'm happy with them. They do the job, and they come with me when I travel. Plus, it makes some intuitive sense to block light at the narrowest point - just in front of your eyes, versus from every possible source.

Great point and I should have added that because it is my solution now as well. FWIW if you have the opportunity to snag a sleep mask from an Emirates international business or first class, do so; it is by far the finest I have used and mine has lasted 6 years now.

Sleep masks make me sweaty and squish my eyeballs. I opted for tying a silk scarf around my head instead. Luxury.

The branding is a bit silly. But. You can open your eyes and it remains pitch black--zero light leakage. I started using them on flights, now use at home when I really need the extra z's.

Awesome!
