Amsler (botany)
The Amsler grid is a tool used in botany and vision science to assess visual distortions. It is a square grid with a central point, designed to help detect changes in visual perception, particularly in the context of macular health. When individuals look at the grid, they may notice wavy lines or missing areas, which can indicate problems, such as those caused by issues in the retina—the part of the eye responsible for sharp vision. In botany, this tool is particularly relevant when studying plant structures and their interactions with light and visual perception.
