What is a visual field and what are visual field defects?
The visual field is the total area in which objects can be seen in peripheral vision while the eye is focused on a central point. If you think of your field of vision as a wide half circle visual field restriction can block the right or left portions of the hemisphere, or one of the corners or the lower portion of the hemisphere. To see for yourself what it may be like to have a visual field defect, visit our visual field simulations developed for e-advisor, a resource for families and teachers of visual impaired children.
