In the lightless depths of the Arctic, a creature that has circled the Earth for four centuries quietly challenges what we thought we knew about aging and sight. Researchers at UC Irvine have discovered that Greenland sharks — long presumed blind — maintain fully functional vision across lifespans that dwarf recorded human history, sustained by DNA repair mechanisms that protect the retina from the slow erosion of time. What began as a single observation of an eye tracking light in dark water has opened a corridor between the biology of the deep sea and the clinical reality of human vision los
