I've had 5 or 6 visual fields tests. I'm not sure how accurate they were. I had trouble coordinating the clicks I was supposed to do with the appearance of the lights on the screen.

By the time I would get around to clicking, the test would have gone on to the next light.

The charts for this test can be interesting. One of mine showed almost no peripheral vision, and others showed considerable loss of central vision.

I had all of these visual fields tests done in an ophthalmologist's office. At least they aren't painful or uncomfortable.
