This is a test for your peripheral vision. Many different eye conditions, such as glaucoma and optic neuritis can affect your peripheral vision as well as your central vision. Field tests reveal if there is any loss of peripheral vision, often not detected because we normally use our central vision. It is common to have to repeat visual field tests on a regular basis to check if there has been any change.

  Field tests take approximately 15 minutes to complete. Points of light are flashed onto a screen and you press a button when you observe a flash. The automated Humphrey Field Analyzer is used at Vision Centre.
