About Roudy Nassif

As a child, Roudy began suffering from ADHD, headaches and eyestrain. His struggle continued as he grew older, with Roudy becoming a night owl and often feeling depressed, fatigued, and disoriented. After consulting so many doctors, and trying every diet, supplement, and healing modality, nothing seemed to work. 

The frustration of living in pain drove Roudy to a journey of learning about himself and nature, which transformed his health and life. That’s when he discovered Light and Circadian Biology.

Now, as a renowned engineer, health entrepreneur, martial artist, and light expert, Roudy’s mission is to help people experience the freedom, flow, and vitality of living in rhythm with nature’s light and dark cycles, and achieving better sleep and increased energy. Roudy is the founder of Vivarays, leading the Light Revolution.

His company 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.
