Your visual field is how wide of an area your eye can see when you focus on a central point.


Visual field testing is one way your optometrist measures how much vision you have in either eye, and how much vision loss may have occurred over time.

At Medioptics, we use the Humphrey Matrix Visual Field analyzer.


The Humphrey Matrix uses frequency doubling technology, which enables the detection of visual field defects in the very early stages. This is particularly important for people with glaucoma as most people are unaware that they are developing glaucoma until the disease is well established.


Earlier detection of subtle visual field loss in early glaucoma using this machine improves the success of treatment in glaucoma to help prevent avoidable vision loss.
