The 60-Second Light Leak Test: How to Check Any Eye Mask Around Your Nose and Cheeks

Quick answer: Wear the mask in a bright room, close your eyes, turn toward a light and look for thin bright lines at the nose and the edges. Then re-seat the mask and tighten the strap until the lines disappear.

Why does light leak around an eye mask?

Faces are different shapes. A mask that is too loose, too flat or tilted will leave gaps, most often beside the nose.

How do you run the 60-second test?

1. Seconds 0 to 10: Sit near a window or lamp. Put the mask on with the strap centered at the back of your head.
2. Seconds 10 to 30: Close your eyes and slowly turn your head left and right. Notice any bright slivers.
3. Seconds 30 to 45: Press the nose area gently. If the light vanishes, the bridge needs a snugger fit.
4. Seconds 45 to 60: Adjust the strap one notch and test again.

How do you fix a leak at the nose?

Tilt the mask slightly down, seat the bridge on the nose first, then pull the cups into place. Contoured designs such as the MigraineMend mask are shaped to follow this curve.

How do you fix a leak at the cheeks?

Lower the strap slightly so the lower edge sits flat on the cheekbone, and make sure hair is not under the edge.
