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).
