For most of his life, Roudy Nassif spent nights staying up late, waking up feeling exhausted, unmotivated and unfocused. After visiting so many doctors, trying different diets, supplements, herbs, nothing seemed to work.
About 7 years ago, Roudy's depression and anguish became unbearable so he decided to leave his job as an engineer and embark on a worldwide journey of learning about himself and nature.
Roudy's experiences transformed his health and life. His quest to understand this transformation and help others led him to study light, quantum biology and the circadian rhythm. Thus, VivaRays was born
Roudy has been educating thousands of functional medicine and naturopathic doctors about the power of light and helping them optimize their personal as well as their patients' wellbeing, sleeping patterns, energy and focus.
His company VivaRays is responsible for introducing the world's first circadian light-harmonizing eyewear. These glasses harmonize the bad effects of artificial light coming from screens and indoor light bulbs, helping individuals sync with nature's rhythm for a more vibrant life.
