(Washington University School of Medicine) Ever wonder how your eyes adjust during a blackout? When we go from light to near total darkness, cells in the retina must quickly adjust.

Vision scientists at Washington University School of Medicine in St. Louis have identified an intricate process that allows the human eye to adapt to darkness very quickly.

The same process also allows the eye to function in bright light. The discovery could contribute to better understanding of human diseases that affect the retina, including age-related macular degeneration.
