Blue visual field defect

The "field of view" is also known as the "field of view". When the eye is fixed and fixed (or through the instrument), the range of space that can be seen, the binocular field of view is greater than the monocular field of view: the field of view of various colors is also small, the green field of view is the smallest, and the red field of view is red Larger, blue is bigger, and white is the biggest. If the tissue that controls blue in the eye is abnormal, a color visual field defect will occur, and the blue visual field defect is the same reason.
