He or she will give you a visual field test to determine where your blind spots are located. If you feel you are losing your peripheral vision, you should see an eye doctor immediately. Compressed optic nerve head (papilledema).Optic neuritis and other conditions that cause neurological damage.Brain damage from stroke, disease, or injury.
Additional causes of peripheral vision loss may include: Many eye care professionals agree that the loss of peripheral vision (also known as peripheral field deficit) is linked to nerve damage, which can be caused by glaucoma or injury, among other things. Symptoms of peripheral vision loss-which may be very subtle, and may not even be detected by the patient-may include difficulty seeing in dim light and a decrease in ability to navigate while walking. So what happens when we lose our peripheral vision? Let’s go over that now. Cone cells are concentrated in the center of the retina and enable us to see bright lights and color. Rod cells are essential for seeing in dim light, but they are unable to distinguish color. There are two types of receptor cells: rod cells and cone cells. The receptor cells on the retina are densest at the center-the area known as the macula-and more diffuse at the edges. The retina is a layer of tissue located in the back of the inner eye that converts light images to nerve signals and transmits them to the brain. This is due to the density of the receptor cells on the retina. Peripheral vision is weaker in humans than in many other species, and this disparity is even greater where it concerns our ability to distinguish color and shape. The opposite condition-the loss of your central vision while retaining your peripheral vision-is known as central scotoma. The loss of peripheral vision results in a condition known as tunnel vision. Most people do not appreciate their peripheral vision until they begin to lose it. Near-peripheral vision: the vision just adjacent to the center of gaze Mid-peripheral vision: the vision in the middle of the field of view Peripheral vision is broken down into three segments of the field of view:įar-peripheral vision: the vision at the edge of the field of view A normal visual field is approximately 170 degrees around, with 100 degrees comprising the peripheral vision. Peripheral vision is the part of our vision that is outside the center of our gaze, and it is the largest portion of our visual field. These objects lie outside your central field of vision, in what is called your peripheral vision. While staring straight ahead and without moving your eyes or head, try to be aware of the objects to the left and right, above and below you.
