Scientists map the eye to unlock secrets of fading night vision

This study aimed to understand the link between poor night vision and the early stages of age-related macular degeneration (AMD), a common cause of vision loss in older adults. Researchers followed 556 participants, including older adults with and without early AMD and a younger comparison group, over three years. They used detailed eye scans and vision tests to create a map of how changes in the eye's structure affect a person's ability to see in the dark.
