visual field charts

Visual field charts are tools used to assess a person's peripheral vision, which is the ability to see objects outside of their direct line of sight. During a visual field test, a person looks straight ahead and is asked to identify when they can see flashes of light in their peripheral vision. The results are recorded on a chart, showing areas of vision loss or restriction. This information can help diagnose conditions like glaucoma, retinal diseases, or neurological disorders, providing valuable insights into a person's overall eye health and visual function.
