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.

    Disappointing

    I love supporting small businesses and trying new products, and I was really excited for this mask. It’s branded as a top-of-the line product which would have been the perfect upgrade from my current sleep mask. Unfortunately, this product fell below expectations. The mask itself feels rather jagged, maybe it was too costly to provide better curvature which would have fit better. As a result, it felt awkward and it leaked in light. I tried adjusting the eye cups but it didn’t help much. This product does not feel like a top-of-market mask. I prefer my existing mask, which has more curvature, is softer, and blocks light better… and it costs a bit less! Then it gets even more disappointing. At the bottom of the product page there is a button which says “30-day return policy”. It is not mentioned on the product page that this is a non refundable product.

    ,

    I hope you will be honest and transparent and allow this review to remain on the site. I hope this promising company will improve transparency by indicating clearly on the product page when an item is non refundable. I hope that they can improve this sleep mask and deliver a truly best in class product, where I will happily pay top dollar. But this one, unfortunately, ended up in the trash bin.

    Not Suitable For Stomach Sleepers

    I don't like this Deluxe Delta Blackout Sleep Mask. It's not ideal for stomach sleepers mainly because it feels bulky and uncomfortable around the eyes, there is light intrusion, but also it leaves compression wrinkles around my eyes. Trying out this new sleep mask in order to avoid wrinkles was the main reason why I purchased it. After relying upon the more expensive Manta Pro Sleep Mask for 9 months, I now can't seem to shake off this 8cm-long diagonal wrinkle on my forehead after wearing it. But because the Deluxe Delta Blackout Sleep Mask produces more pronounced compression wrinkles around my eyes, I now have no choice but to revert back to using the more comfortable Manta Pro Sleep Mask. Not to matter. In the meantime, I think I will continue buying other brands of sleep masks until I find the right one that ticks all my boxes.

    Impressed!

    It really does block out the light and is comfortable. I’m still getting used to sleeping with it, but it is impressive how much light it blocks out whilst also not pressing on my eyes.

    This sleep mask is comfortable to wear, and seem's to block out all light.

    Best Eye Mask

    I have tried a few different eye masks and I have never found the right fit. They either slip off my head during the night, press too firmly on my eyes and never fully block out light. After a recommendation from an OT, I gave this a go and I can safely say I am not disappointed! It is the perfect eye mask and I have never slept more soundly. It is on my Christmas and Birthday wish list so I can have spares!

    Night time bliss.

    I love the mask. It completely covers my eyes and everything is completely dark. Don't need to worry about needing blackout blinds any more as they still let light in around the edges. I have to let people try them on so they'll believe me.🙂

    Nothing but black!

    I'm loving this mask! I had been using a 'standard' sleep mask which had been ok until recently moving into a new house with a lot of light coming in through the windows at night! Upgrading to this sleep mask has been a game changer!
