Shulux 3D Blackout Sleep Mask is designed to help block distracting light while deep contoured eye cups leave space around your eyes.
This sleep mask is made for people who want to rest when surrounding light is distracting, whether at bedtime or during a nap. Its shaped eye area and face-following profile address common comfort needs around the eyes, nose and temples. The design is intended for nightly sleep as well as travel, flights and meditation.
Yes. The deep contoured eye cavities create space around your eyes, helping reduce contact with eyelids and lashes so you can blink naturally. Unlike a traditional flat sleep mask that rests across the eye area, this 3D shape is designed to avoid a pressed-eye feeling while you rest. Its purpose is to help block distracting light without relying on a flat panel pressing against your eyes.
It is designed for both side and back sleepers. Soft cushioning and the face-hugging shape are intended to help reduce pressure around the eyes and temples when your face meets the pillow. The contoured nose area follows the shape of your face to support a closer fit, rather than leaving the nose area shaped as a flat edge.
The mask combines OEKO-TEX certified fabric with cushioned memory foam, and its soft-touch materials are designed for prolonged skin contact. An adjustable strap supports a secure, personalized fit; adjust it to suit your comfort rather than adding unnecessary pressure. The mask is also intended for naps and meditation, as well as travel and flights, so its use is not limited to a nighttime routine.
