A normal eye view refers to the extent of the visual field that a person with healthy eyes can perceive.
In more detail, the normal visual field encompasses the area a person can see when their eyes are fixed on a single point. This field is not uniform in all directions. Here's a breakdown:
-
Horizontal Range: A normal eye can typically see over 120 degrees horizontally. This means that, without moving their eyes, a person can see objects located more than 60 degrees to either side of their central line of sight.
-
Vertical Range: Vertically, the normal visual field spans approximately 90 degrees. This means a person can see objects roughly 45 degrees above and 45 degrees below their central line of sight without moving their eyes.
Therefore, the "normal eye view" represents this wide-ranging, binocular visual field that allows for a comprehensive perception of the surrounding environment. Deviations from these ranges can indicate potential visual impairments.
