How It works

Disrupted circadian rhythm leads to poor sleep

A healthy circadian rhythm is the foundation for a good night’s sleep. However, in modern days, many of our activities compromise this foundation, leading to various sleep and health problems.

Lumos Smart Sleep Mask

Setting a healthy foundation for sleep

Lumos uses patented light technology to help you strengthen this foundation, so you can enjoy a good night’s sleep.

Select program

Whether it’s traveling, working night shifts, or simply wanting to fall asleep or sleep through the night, Lumos will guide you through the right program.

Set schedule

Input your schedule to set up the program, and follow the instructions on when to use the mask.

Wear mask

Before going to bed, simply put on the mask and start the program. Wear the mask throughout the night.

Why light therapy?

Light is the most effective regulator of our body’s circadian clocks. Studies from Stanford have shown that short light pulses are effective in adjusting human circadian clocks. When applied at night during sleep, the light flashes from Lumos Mask penetrate through your eyelids and send signals to change your circadian clocks.

How can it help me sleep?

A good night’s sleep starts with a dialed circadian clock. In modern days, many of our activities result in a misaligned circadian clock, leading to difficulties falling asleep and staying asleep, or trouble waking up in the morning.

Whether you are traveling or working night shifts, or just simply want to improve your sleep, Lumos offers different modules to help you navigate the process of strengthening your foundation of sleep.

Frequently Asked Questions

Let's answer your questions about lumos mask

Is the Lumos light therapy safe?

Human-subject studies conducted at Stanford Sleep Center using millisecond light pulses on hundreds of participants have not shown any known negative side effects to this point. Lumos Smart Sleep Mask is designed to mimic the light programs used in the Stanford studies. So far, only about 5% of our users have reported sleep disruptions from the lights, and 1-2% reported other possible side effects, all of which are minor.

Additionally, the light intensity from Lumos Smart Sleep Mask is orders of magnitude lower than the intensity of light a human eye will be exposed to during normal activities on a typical sunny day. The pulse frequency is orders of magnitude less than the frequency that can induce seizure and epilepsy.

Despite the safety evidence from lab studies, we recommend that users who are on non-sleep medication or suffering from any sort of serious medical conditions check with their doctor before using the Lumos Smart Sleep Mask, and discontinue use if experiencing any adverse reactions such as dizziness or migraines.

Is the mask hard or soft?

We understand that no one wants to wear a hard device to sleep, so we have spent a lot of time working with our testers to make sure that the mask is light, breathable, soft, and comfortable.

How do I charge the Lumos Sleep Mask?

The Lumos Smart Sleep Mask is charged by MicroUSB, making it easy and convenient to recharge wherever you are.

How do I keep my Lumos Sleep Mask clean?

The removable cover in the Lumos Sleep Mask makes it easy to clean and maintain. The cover is made from a soft and comfortable material that feels great against your skin, but over time it can become dirty and stained from regular use. In that case, all you need to do is remove the cover and wash it in a laundry bag in the washing machine and then air dry to keep it clean and fresh.

Can I easily bring Lumos onto the plane with me? Is the battery a concern?

According to the FAA, products with lithium batteries will be allowed in both carry-ons and checked bags, so Lumos is compliant with regulations when packed either way. Always good to check the latest regulation to be sure.

Is the Lumos Sleep Mask suitable for all head sizes?

The Lumos Sleep Mask has an adjustable strap, which allows you to adjust the fit to your specific head size and shape.

Can I use the Lumos Sleep Mask with my CPAP machine?

The Lumos Sleep Mask is designed to fit comfortably over your eyes, therefore it won't interfere with the operation of your CPAP machine. We do understand each person has a different preference, so you will get to decide if this works for you.
