Visual Field Graphic

The numbers show the visual field quality, the bigger the number, the better the vision

Lower numbers have darker shades, showing areas with poor vision. Black areas (with 0 value) show areas with no vision at all.

White areas indicate perfect vision.

 

A healthy eye will show a vision field with most values between 20 and 30, a few 40's and only one or two 0's, showing the normal blind spot.
