BioHackers Lab: Health Show for How to Live Your Best Life How Red Light Helps Our Vision and Blood Glucose Levels: Dr Glen Jeffery PhD
Feb 11, 2025
Dr. Glen Jeffery, a neuroscience professor from University College London, discusses his pioneering research on red light therapy. He reveals how red light can recharge retinal mitochondria, enhancing vision, particularly in older adults. The conversation explores the potential of red light to regulate blood sugar levels and its broader implications for health. Jeffery warns about the detrimental effects of modern lighting, suggesting innovative solutions to improve both eye health and metabolic regulation.

Episode notes
Mitochondria As Rechargeable Batteries
- Mitochondria act like cellular batteries and absorb particular wavelengths of light to boost charge.
- Recharging them with red/infrared light can help cells cope with stress and aging.
Retina Is Exceptionally Energy Hungry
- The retina consumes more energy per cell than any other tissue due to huge luminance adaptation.
- That high energy demand makes the eye an ideal target for mitochondrial light-based therapies.
Use Short Red-Light Bursts For Vision
- Try brief bursts of deep red or infrared light to improve visual contrast and color perception.
- The effect appears stronger in older adults and can be measured within hours.
