How is it done?

At the London Eye Hospital we use the gold standard in visual field screeners – the Humphrey Visual Field Analyser. The test involves placing your chin on the instrument chin rest and fixating a central yellow light. You then press a button when you detect flashes of white light on the surrounding bowl shaped screen.

There are several different tests that can be performed on this screener – your consultant will select the most appropriate type. On average this test takes 5-10 minutes per eye. As well as mapping your peripheral vision the sensitivity of the eye to differing intensities of light is also measured.

Before your appointment:

This test can be performed wearing your contact lenses or reading glasses if you use them.
