Intended use of EVY LIGHT®
The device is intended for 40 Hz brain stimulation and activation of gamma brainwaves.
It is intended to be used in conjunction with a healthy lifestyle to promote mental acuity. The
device does not have any medical indication for any specific patient population. It is intended
but not limited to residential use.
What is Invisible Spectral Flicker?
OptoCeutics has invented a way to make 40 Hz flashing lights more comfortable. Traditional
40 Hz flashing lights can be disturbing, highly uncomfortable to use, and may induce side
effects such as nausea and headaches, especially if used for extended periods.
Instead of flashing 40 times per second between the light being on and off,
EVY LIGHT®alternates between two different combinations of colors that together form a
nearly continuous light, we call it Invisible Spectral Flicker.
(The effect can be seen if you try to record a video of the light.)

4. Follow these guidelines for use
You receive gamma brain stimulation the moment the light from EVY LIGHT® reaches your eyes.
The amount of brain stimulation can vary depending on how it is used but, generally, the following applies:
• The device should be used 1 hour a day, but it can be split up into shorter intervals, e.g. 2 x 30 minutes.
• The device should be within 2-3 ft (50-100 cm) and the light should be within your field of view.
• You don’t have to stare directly at the light, and you can use the device in connection with other activities
(see examples below).
Try using EVY LIGHT®while eating, working,
reading, listening to music, or watching TV.

PLEASE NOTE:
The highest brain response is seen when looking directly into the light. If you wish to look directly into the light,
the focus point (4) can aid your eyes. However, it is better to find a comfortable use where you will use EVY LIGHT®
consistently. The above methods can be used to prevent eye strain and achieve consistent use.
Front Indicators
There are four indicators on the front of the device (5).
For each 15 min the light has been turned on, one indicator will light up. After 60 min all four indicators will light
up for about 1 min before the light turns off completely.
Brightness Control
You can change the brightness of the device
by pressing and holding the front button for 2
seconds. The front indicators will start blinking
and indicate which of the four different brightness
settings you have chosen.
One indicator blinks for the lowest brightness, and
four indicators blink for the highest brightness. Lowest
2 seconds Highest

5. How to track your usage (optional):
You can enable usage tracking on EVY LIGHT®, by connecting the device to the INSIGHT app.
When enabled the camera tracks whether a person is in front of the device and the gaze direction,
so you know whether EVY LIGHT®has been used correctly and for how long.
Usage tracking is NOT enabled by default.
PLEASE NOTE:
The camera data is not shared, and the image is only stored temporarily for gaze direction analysis.
See the included flyer on how to install and use the INSIGHT App, or contact OptoCeutics support.
