Condition focus: Glaucoma & Light-Mitochondria Interactions Glaucoma, the leading cause of irreversible blindness worldwide, involves retinal ganglion cell death driven in part by mitochondrial dysfunction. This review examined how different wavelengths of visual light interact with mitochondria in retinal cells, with particular focus on implications for glaucoma pathogenesis and potential therapeutic interventions. The analysis integrated evidence from cellular studies, animal models, and early clinical observations to evaluate how blue, green, and red/near-infrared light differentially affect mitochondrial function and retinal ganglion cell survival. The review established that light wavelength profoundly influences mitochondrial function through distinct mechanisms. Blue light (400-500 nm) generates excessive reactive oxygen species, damages mitochondrial DNA, and triggers apoptotic pathways in retinal ganglion cells—effects particularly concerning given modern LED lighting prevalence. Green light showed intermediate effects. In contrast, red and near-infrared light (630-850 nm) enhanced mitochondrial function through cytochrome c oxidase activation, increased ATP production, and reduced oxidative stress. Critically, red/NIR light demonstrated neuroprotective effects in glaucoma models by supporting energy-demanding retinal ganglion cells vulnerable to mitochondrial failure. The analysis suggested that environmental light exposure patterns may influence glaucoma progression, while therapeutic red/NIR light could provide metabolic support as an adjunct to intraocular pressure-lowering treatments. WaveFront Alignment: Osborne’s framework linking light wavelength to mitochondrial function in glaucoma validates the Spectral WaveFront’s red/NIR wavelength selection for optic nerve conditions, supporting photobiomodulation as metabolic support complementing traditional pressure-lowering glaucoma therapies.
