1. YFONG Weighted Mask 鈥?Best for Side Sleepers
The YFONG has a 3D eye cutout that creates space around your eyes 鈥?no matter which way you lie, nothing presses on your eyelids. The 120g weight adds gentle pressure that feels like a hand resting on your eyes, which is deeply calming. At $14, it's also one of the cheapest. Read our full YFONG review.
2. MZOO 鈥?Best 3D Contoured Cup
The MZOO is the best-selling 3D sleep mask on Amazon with 20,000+ reviews. The molded eye cups create complete space around your eyes 鈥?you can even open your eyes behind it. The strap is adjustable and doesn't catch hair. At $20, it's slightly more expensive but the build quality is excellent.
3. Alaska Bear Silk 鈥?Best Thin Flat Mask
The Alaska Bear is a flat silk mask 鈥?no 3D cup. But at 22 momme mulberry silk, it's so thin and soft that side sleepers barely notice it pressing. It's the most comfortable flat mask We researched. The trade-off: it doesn't create as much eye space as a 3D cup. Read our full Alaska Bear review.
4. Nidra Deep Rest 鈥?Best Molded Cup
The Nidra has a molded plastic cup that creates eye space. It's similar to the MZOO but slightly bulkier. The rating is a bit lower at 4.3 stars. Good if you want a 3D cup but can't find the MZOO in stock.
5. Mavogel Cotton 鈥?Best Nose Coverage
The Mavogel has a contoured nose flap that blocks light from entering at the bridge. But the cotton fabric is thicker, so it presses more on side sleepers. Good if light leakage is your main problem, not eye pressure.

FAQ
Why do sleep masks press on my eyes when I sleep on my side?
When you lie on your side, the mask's edge presses into the side of your eye socket. Flat masks are the worst because there's no space for your eye to move. 3D molded cups solve this by creating a hollow space around each eye.
Can I open my eyes behind a 3D sleep mask?
Yes, that's the point of the 3D design. The molded cup creates enough space that you can blink and move your eyes without touching the fabric. This is important for REM sleep, when your eyes move rapidly.
Do weighted sleep masks work?
Yes, the gentle pressure (similar to a weighted blanket) has a calming effect. Many users report it feels like a hand resting on their eyes, which reduces anxiety and helps them fall asleep faster.
Final Recommendation
For side sleepers, the YFONG weighted mask at $14 is the best choice. The 3D eye cutout eliminates pressure, and the gentle weight adds a calming effect. If you prefer a non-weighted option, the MZOO at $20 is the best 3D molded cup. Skip flat masks unless you really prefer the silk feel 鈥?they will press on your eyes when you're on your side.
