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.

    Deluxe Delta Sleep Mask - 100% Light Blocking

    very good, i like the way you can move the eye covers, still lets in a tiny pin prick of light though, only a problem if someone turns a big light on.

    Life Changing!

    I didn’t realise how much light comes into my house at night, and how disruptive it’s been for my sleep - until I started wearing this rad mask. It’s made such a difference to both the quality and length of my sleep. I don’t need melatonin anymore, and I wake up totally fresh.

    They were a bit of a learning curve to position but now they’re comfy every time. Highly recommend

    Blockout

    Great for blocking out the light but not very comfortable around the head and moves throughout the night

    Great product

    Bought this off the recommendation of a friend who is also a shift worker. Took me a few tries to get used to having an eye mask, but now i find it comfortable and it does not interfere with my sleep or comfort. Does an excellent job at blocking out light.

    I would love to comment on this, but unfortunately it was bought as a Christmas gift. So at this point I would say the look and feel of the mask is lovely and of a high quality.

    Great product, great sleep!

    I love this mask. This is the second sleep mask I’ve bought from Block Blue Light—the previous was slightly different, and after three years of continuous use it was time for a new one.

    The foam padding is excellent, and I love that there is elastic in the waist band of this one. Although not designed for side sleepers, I sleep on my side with this no problems. I get a great night’s sleep now with this.

    Quite comfortable and blocks practically all light.

    Quite comfortable and blocks practically all light. If you have a small head, the strap is too big and the Velcro doesn't stick well.

    Am in the dark

    I find I sleep better now that I totally in the dark. Can’t see anything through them
