Your visual field is very wide.
You have excellent means to notice things even at extreme sides of your vision because of the excellent width of your visual field.
A wide visual field is necessary for seeing things towards the edges of vision.
Our ophthalmologist Markku explains this indicator:
The eye not only sees straight at the direction of the gaze, but also towards the sides and up and down. If you lift your hand in front of your face and look at your thumb, your little finger is at about 10 degrees from the line of your gaze. If you move your hands to the sides of your head and look straight ahead, you can usually see your fingers moving (if you move them). The width of the visual field is then roughly 90 degrees in both directions, or 180 degrees in total. For up and downwards dimensions, the Ocusweep device measures up to 36 degrees, thus measuring a total of 72 degrees. Here, a larger number is better.
A lowered width of visual field is difficult to notice, because one’s brain tends to fill the missing areas. This can be dangerous for example in traffic. You may endanger your own safety or that of others if your visual field is not wide enough. On the other hand, if you take the limitations of your visual field into account, you can improve the safety of those around you.
Signs of narrowing of the visual field:
Ocusweep functional vision examination measures the functioning of the visual system with both eyes - just as we use both eyes simultaneously in everyday life. This measurement is not a replacement for an eye health examination, where each eye is tested on its own while the other eye is blindfolded.
