It is quite possible to lose areas of your vision in one or both eyes without being aware of it. This is partly because you have two eyes and partly because the human brain is so good at adapting to ignore areas of visual loss.

We are not aware of the blind spot in our vision caused by the aperture for the optic nerve, nor can we see the blood vessels at the back of the eyes which lie over the light sensitive layer.

Visual field screening enables us to pick up areas of visual loss which could indicate a number of different eye or health issues.

For this reason we include visual field screening for the majority of our adult patients and for children where symptoms indicate it.
