Test your field of vision

Anyone who notices a sudden movement out of the corner of his eye will snap his head around. This reflex lets us react to danger in good time. Test now to discover the range of your field of vision.

1

Important: Do not wear glasses for this test.

2

Cover your left eye with your free hand. Look straight ahead and keep looking in that direction while you move the pen slowly in an arc to the right with your outstretched arm.

3

Stop at the place where you pen disappears from your field of vision.
If you have a normal sized field of vision, your arm should be at a 90° angle from the starting point of the movement.

4

Carry out the same movement on the other side of your body until the pen disappears from your field of vision. The angle should be somewhat smaller, approximately 60°, because your nose limits your field of vision on that side.

Analysis

If you have the impression that you don't reach the given angle, they you should definitely see an ophthalmologist.

 
 

The field of vision

The field of vision is what we see when we look straight ahead with our head held straight.

It covers everything that is depicted on the retina. All the surroundings that you can in fact perceive are part of this – even if they are not sharp and you can’t regonize them cleary.
