About the series

Designed for practitioners, researchers, and health professionals, these free evidence-based learning sessions explore the cellular mechanisms and science behind brain photobiomodulation (PBM).

Each session reviews peer-reviewed literature and emerging pilot data across various cognitive and physiological domains, detailing how Vielight systems are implemented in academic and institutional research.

This information provided is based on published research and not medical advice.

Our lectures
Dr. Lew Lim
Dr. Charles Shidlofsky
Dr. DeAnn Fitzgerald
Dr. Neda Rashidi-Ranjbar
Dr. Lew Lim Founder & CEO
He is widely recognized as an expert on photobiomodulation (PBM), particularly in its application for brain functions and the effect on the immune system. He owns the largest number of worldwide issued and pending patents related to PBM as an individual.
Dr. Charles Shidlofsky Doctor of Optometry
He is a neuro-developmental optometrist at Neuro-Vision Associates of North Texas, a part of the DeyeNAMICS Alliance. With a passion for neuro-developmental optometry, Dr. Shidlofsky has dedicated his career to creating and implementing innovative therapies for children facing vision-related challenges, including those with ADD/ADHD, autism spectrum disorder, and sensory processing disorders. His expertise extends to addressing vision problems associated with traumatic brain injuries, strokes, and other neurological processing issues.
Dr. DeAnn Fitzgerald Doctor of Optometry
She is the immediate Past President of the Neuro-Optometric Rehabilitation Association (NORA), an inter-disciplinary group of professionals dedicated to providing patients who have physical or cognitive disabilities as a result of an acquired brain injury with a complete ocular health evaluation and optimum visual rehabilitation education and services to improve their quality of life.
Dr. Neda Rashidi-Ranjbar Clinician Scientist
She is a Clinician Scientist holding both an MD and a PhD, currently serves as a postdoctoral fellow at St. Michael’s Hospital. She earned her doctoral degree in medical science from the University of Toronto. At present, Dr. Nana is at the forefront of pioneering research focused on the application of photobiomodulation (PBM) for the treatment of Mild Cognitive Impairment (MCI).

Our Masterclasses

Photobiomodulation and Alzheimer’s: Mechanisms and Research Findings Watch the video

Photobiomodulation and Alzheimer’s: Mechanisms and Research Findings

Dr. Lew Lim and Dr. Neda Rashidi discuss the underlying cellular mechanisms of brain photobiomodulation (PBM) and its role in cellular health. They also review published exploratory research examining PBM’s effects on general cognitive performance, memory measures, and brain function.

Neuro-Optometry: Intranasal Plus Transcranial Photobiomodulation Watch the video

Neuro-Optometry: Intranasal Plus Transcranial Photobiomodulation

In this Masterclass, neuro-optometrists Dr. DeAnn Fitzgerald and Dr. Charles Shidlofsky discuss how they integrate dual-pathway (intranasal and transcranial) photobiomodulation (PBM) alongside visual and vestibular training protocols. They explore the connection between cellular energy, autonomic balance, and neural adaptability, sharing clinical insights on how combining the Vielight Neuro with neuro-visual training helps support visual processing, focus, and overall functional performance.
