Photobiomodulation

Red light therapy (or Low Level Laser Therapy) that exposes the retina to near-infrared or infrared light in the range of 650-1100nm. The red light ‘reactivates’ aged mitochondria in the Ellipsoids of Photoreceptors, which improves Color Contrast Sensitivity. However, the effect is small and only applies to people 40+ years old. It cannot alleviate color blindness.
