Just a tiny amount of light hitting your eyes whilst you sleep can have a dramatic impact on melatonin levels and sleep quality. In today's modern world, we are surrounded by light pollution; street lighting and indoor technology cause tons of light pollution during the night. Keeping a pitch-black sleeping environment is near impossible! 

Using the Deep Sleep Delta Sleep Mask completely eliminates 100% of light entering your eyes. This creates "pure darkness" for your brain, which then increases your Deep and REM sleep.

We have custom-designed wider and deeper memory foam eye cups that allow you to fully block 100% of light hitting your eyes while still being able to open and close them. These cups are made with super soft, breathable, and durable materials that gently cuddle your face without putting any pressure on your eyes.

Conventional sleep masks don't always fit all head shapes and sizes, letting in too much light through from the top and under the nose area. On the other hand, the Deep Sleep Delta Sleep Mask has adjustable eye pieces that Velcro on and off so you can position them exactly to your face shape, ensuring a 100% blackout and a perfect fit every time.
