How 3D Facial Technology has been used to provide complete light block out

According to a fascinating and slightly scary website called Worldometers (https://www.worldometers.info/world-population/) – where you can watch the world’s population increase before your very eyes, there are 7.9 billion of us on this planet  (depending when you read this).

Our bodies come in all different colours, shapes and sizes, and our heads are no different. So how on earth do you produce a face mask for sleeping that will fit all of those people and effectively block out light?

Well, the way Dreamlight decided to tackle the challenge was to recruit more than 3,000 people from all over the world and study the shape and contours of their face using technologically advanced 3D facial mapping.

This helped greatly in the design process by guiding the cushion distribution around sensitive facial areas. For complete light block out it needs to be a snug fit, but not so tight that it puts pressure on the face or head to create discomfort.

The results speak for themselves – Check out the Smart Wellness range of Dreamlight Sleep Masks here.

Dreamlight masks sit comfortably on the head, minimising pressure on the eyes, distributing weight around the back of the head and providing ample padding for the nose.

The masks are also made from a soft, resilient material with a spacious hollow design around the eyes. Adjustable Velcro straps for a secure fit.

Is 100% light block out important?

Light is the ‘enemy’ of sleep. Whether it’s daylight, artificial room lighting or the blue light of screens, even the smallest exposure can stimulate wakefulness. In fact, a study investigating the impact of just 5 minutes of light exposure through the evening, (for example, a bathroom visit from your partner), triggered a delay melatonin release by a staggering 2.3 hours, leading to the inability to sleep through the night, and greater morning fatigue.1

Melatonin is a natural hormone secreted by a gland in your brain (pineal).2

Exposure to darkness tells the pineal gland to start producing melatonin while exposure to light causes that production to stop. Melatonin helps regulate our circadian rhythm or body clock and synchronize our sleep-wake cycle, so we’re asleep when we should be and awake when we need to be.3 Melatonin is usually released a couple of hours before your normal bedtime4 (which is why going to bed at the same time each night is a good idea).

In contrast, exposure to light shuts down production of melatonin.5

That’s why sleep experts advise you to keep lights low before bedtime and definitely stop using computers, tablets and smartphones.6
