What is a Humphrey Visual Field test?
This is a test for your side 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 side vision which is 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 30 minutes to complete.
