40 Hz light stimulation is exposure to light pulsing at 40 hertz, which is 40 times per second. That’s very stroboscopic… we know, that’s why we engineered a way to mask it so the brain received the proper stimulation without having to sit near bright strobing light.

Put simply, EVY LIGHT® is designed to synchronize a particular type of electrical activity in the brain known as gamma waves.

High gamma activity is associated with greater performance in memory, mood, learning, and sleep. Situations where we are under great pressure and need to provide greater performance, gamma activity in the brain increases.

In fact, the lack of proper gamma waves or altered gamma brain waves, (which is very common in aging), have been heavily observed in cognitive disorders, such as Alzheimer’s / dementia.

Due to these observations, recent studies suggests that gamma wave stimulation has great potential to slow major brain diseases and disorders, such as, you guessed it – Alzheimer’s / dementia.

The black dot was added to EVY LIGHT® from user feedback and experimental testing.

According to our users, it helps focus the gaze if looking directly at the light without causing eye fatigue. 

Please be aware that legally our device is still considered experimental.

EVY LIGHT® is not a medical device – it is not intended to diagnose, treat, cure, or prevent any disease or health condition.

Our ongoing animal and human clinical trials are currently in progress to determine the full health efficacy of our technology, as well as several other research studies with recognized institutions to investigate the efficacy of our solutions.

We encourage you to look at other research groups such as Cognito Therapeutics who also examine the efficacy of 40 Hz brain stimulation.

Absolutely not! It is completely non-invasive with great cognition enhancing potential.

Not only is Masked 40 Hz Light patented with OptoCeutics, but our technology within EVY LIGHT® is completely safe.

EVY LIGHT® is CE marked and FCC marked, meaning that we have verified compliance with the essential safety requirements as indicated in the applicable American plus European Directive and Regulation bodies. We have also investigated the safety of the intervention in our clinical study ALZLIGHT Pilot.

We recommend being mindful in using EVY LIGHT® near the 4 hours before going to bed, as it could alter your sleep pattern, but it truly depends on the individual, as some people prefer it near bedtime.

Moreover, people who suffer from photosensitivity or are susceptible to epileptic seizures might negatively react to the stroboscopic effect of the light, even though it’s barely visible. Therefore, we encourage anyone who might be at risk to first contact their doctor before using EVY LIGHT®.

Absolutely not. We have developed an “eye-tracking” function with a small monitor on the device so that it can measure how much brain stimulation you are getting and how long you look directly at the light.

The data is saved but the image is deleted immediately, as the eye-tracking does NOT have the capability to collect personal information or images.

Yes, we recommend it. In case you lost yours or it was accidentally tossed, you can access a digital copy here.


EVY LIGHT®, or OptoCeutics Masked 40 Hz Light, is quite simple to use.

➤ Sit down, turn on the light and look at it or near it for 1 hour (it can also be used for 15 minutes four times a day or 30 minutes two times a day; it will be difficult to overuse the device, as there are limited side effects).

➤ The light is most effective when used for a minimum of 60 minutes a day (preferably in the first half of the day, and at least 4 hours before going to bed).

Please refer to our User Manual for more details.

Exposure to bright light at the wrong times alters the body’s internal clock, or circadian rhythm, and can make your brain stay up later than you intend.

That’s why, for example, it is ideal to avoid using a mobile phone or laptop before bedtime.

A good sleep-and-wake cycle is extremely important for many functions in our everyday life. We recommend that you use EVY LIGHT® through the first half of the day, if possible.

➤ Choose a comfortable area and seat to sit on that is approximately an average arm’s length away from EVY LIGHT®.

➤ Place the device at an appropriate height near your face, so you do not have to strain your neck to look at or near it.

➤ Make sure that EVY LIGHT® is placed on a stable and secure surface.
