Amsler, Hermann

Hermann Amsler was a Swiss physician best known for developing the Amsler Grid, a diagnostic tool used to assess central vision and detect visual distortions. The grid consists of a simple pattern of horizontal and vertical lines, which helps identify issues such as macular degeneration or other retinal problems. When patients look at the grid, they indicate any wavy or missing lines, providing valuable information about their eye health. The Amsler Grid is an easy-to-use test that allows both doctors and patients to monitor visual changes over time.
