3. Setup and Adjustment
The Manta Sleep Mask is designed for a personalized fit. Follow these steps to adjust your mask for maximum comfort and light blocking:
- Adjusting Eye Cups: The eye cups are attached via Velcro. Gently detach them from the main strap. Position each eye cup directly over your eyes, ensuring they are centered and comfortable. Reattach the Velcro to secure them in place. Experiment with different positions to find the optimal placement that blocks all light without applying pressure to your eyelids or lashes.
- Adjusting Head Strap: The head strap features a long Velcro section for broad adjustability. Place the mask over your eyes and bring the strap around the back of your head. Secure the Velcro ends to achieve a snug yet comfortable fit. Avoid overtightening, which can cause discomfort.

6. Troubleshooting
- Light Leakage: If you experience light leakage, re-adjust the position and angle of the detachable eye cups. Ensure they are snugly fitted around your eye sockets and that the nose bridge area is fully covered. Adjust the head strap for a firmer, but still comfortable, fit.
- Discomfort/Pressure: If the mask feels uncomfortable or applies pressure, loosen the head strap slightly. Re-position the eye cups to ensure they are not pressing against your eyes or temples. The deep-molded design should prevent direct contact with your eyes.
- Mask Slips During Sleep: Tighten the head strap slightly. The snag-free fasteners are designed to hold the mask in place without catching hair. Ensure your hair is not interfering with the strap's grip.
