Peripheral vision: Visual field testing is used to measure peripheral vision in diseases that affect the optic nerve like glaucoma. The number of degrees usually refers to span of vision in the horizontal plane with both eyes together, used for legal definition or drivers license. 130 degrees is the angle between the left and right edge of your pripheral vision. Normal is about 180. Minimum to drive is about 120.

Visual field driving: Severe (end stage) glaucoma causes peripheral vision loss (tunnel vision) . Open angle is most common. Florida requires that you have at least 130 degrees of uninterrupted horizontal visual field in order to drive (along with acuity and other requirements). This is because severe peripheral visual field loss would mean that you might not see a car or person entering the road from the side.
