| Protects retinal cells and boosts mitochondrial energy |
Photobiomodulation at 670 nm red light (and 810 nm NIR) enhances mitochondrial metabolism in retinal photoreceptors, reducing oxidative stress and inflammation from blue-light damage. |

| Supports visual function and slows AMD progression |
Multiwavelength light therapy significantly improved visual acuity and reduced progression of geographic atrophy in dry age-related macular degeneration over 13 months, compared to sham treatment. |

| Improves brightness perception and contrast in aging eyes |
Daily brief exposure (3 minutes) to 670 nm red light improved color contrast sensitivity and dim-light vision in adults over 40, likely by revitalizing retinal cellular energy (ATP production). |

| Protects against bright-light and oxidative damage |
In animal models, red and NIR light reduced markers of inflammation and retinal damage, suppressed stress in supporting glial cells (Müller cells), and boosted mitochondrial function to prevent light-induced degeneration. |
