Red Light Therapy Eye Treatment Explained: What Actually Works? | Dr. Robert Dotson
Red light therapy for eye health is everywhere right now, but what’s real, what’s hype, and what actually works? Dr. Joseph Allen sits down with ophthalmologist Dr. Robert Dotson to break down the science behind photobiomodulation, red light therapy, and how it may impact conditions like dry eye, macular degeneration, and more.
With over 40 years of experience and decades researching light-based treatments, Dr. Dotson shares what the research really says about wavelengths, safety, dosing, and the growing number of at-home devices entering the market.
In This Episode, You Will Learn:
✅ What red light therapy (photobiomodulation) actually is
✅ How red and near-infrared light affect eye health at a cellular level
✅ The role of mitochondria and ATP production in healing
✅ Why wavelength, power, and dosage matter more than you think
✅ The truth about at-home red light devices like Arun Light
✅ Safety concerns when using light therapy around the eyes
✅ How red light therapy may support macular degeneration and dry eye
