How do we have the ability to blur our vision on command?
In: 1
By crossing your eyes, inward –>0|0<— or outward <—0 | 0–> , you take your eyes out of sync. The eyes are no longer focusing on the same field of view/object, thus creating this blurred effect.
Also, any liquid or small object will also distort your vision. Reason being is that even though both of your eyes are trying to focus on the same field of view/object, the liquid/small object in your eye is obstructing a perfect picture. Your eyes combine a picture from your left eye and your right eye to make 1 combined picture. This creates the one picture when you see regular. Any distortion to any eye will create a blurry vision.
