Visual field screenings are routinely recommended for people of all ages to identify various vision problems. Your peripheral vision field can provide useful information that will help your optometrist identify potential eye conditions that can affect your ocular and overall health.
Read on to learn more about visual field tests, the information that they can gather from screenings of your peripheral vision, and the eye conditions and other neurological conditions that they can help detect.
What is a Visual Field Test?
Your visual field is made of your central vision, as well as your peripheral vision. Your central vision refers to things that are visible directly in your line of sight. Your peripheral vision on the other hand refers to the visual fields above, below and to the sides of your central vision.
As such, a comprehensive screening of your complete visual field can help detect various things regarding your ocular health, including abnormalities and potential eye diseases. This can be achieved through a visual field test or screening. These tests can evaluate the range of your peripheral vision without you needing to shift your gaze, as well as the degree of sensitivity in your peripheral vision.
At Optometrists' Clinic Inc, we offer a wide range of eye exams including visual field tests.
