By using a headset for peripheral vision testing, you can get a better picture of the field of vision you actually have, and what you should have. A visual field test can also help the doctor find out more about the part of the nervous system that allows us to see. The visual part of the nervous system includes the retina , the optic nerve , and the brain itself. Problems with any part of this system can change the visual field. There are well-known patterns in the test results that help doctors recognize certain types of injury or disease. By repeating more visual field tests at regular intervals, doctors can also tell whether the patient is getting better or worse.

For example, a Humphrey Visual Field test may be administered in order to rule out glaucoma. To do this test, you will check each eye separately and hold the grid about 14 inches away from your face. Focus on the dot in the middle, and you should be able to see the horizontal and vertical lines in the grid as straight and unbroken. If you are unable to see where the lines intersect, or if they are broken or distorted, this could mean that you have a blind spot in your field of vision. Your central vision, made up of the fovea, only makes up a very small portion of your visual field. It is responsible for helping you see things clearly and in high resolution.
There are some DIY at-home visual field exams you can do to determine if your peripheral vision is in good shape. You are going to need a friend to help you do this test. You and your friend should sit facing each other, roughly two feet apart at eye level.

For example, your friend covers his or her right eye, and you cover your left eye.

Similar to an automated perimetry test, this field of vision test uses moving light targets as opposed to blinking or flashing lights to assess your range and field of vision. Stick the pushpin you used earlier back into the cardboard, this time just short of the spot where you originally placed the pencil to start tracing. This will serve as your focal point while you take the test.
This test requires your eyes to be dilated and held open while a small electrode is placed onto your cornea. You are directed to look into a machine that flashes lights, so the electrode can measure the electrical activity in your eye in response to the lights. Your field of vision includes both what you can see clearly right in front of you and what you can see less clearly off to the sides. You can measure your current frame from screw to screw, which is already a perfect fit for you . This measurement would be your ideal frame width that is the most necessary measurement. But keep in mind, all eyewear is different, so it’s just a general reference.
Right now you are reading the words in this newspaper with both your eyes. Use the attached pencil to draw a half circle on your board with a radius of 30 centimeters.

Youll be advised to stay hold your head still with vision focused straight ahead. Then you have to press a button whenever you see flashes of light at different points around the bowl, without tilting your head sideways to see them. The visual field test can help the doctor find early signs of diseases like glaucoma that damage vision gradually.
