Question

Define persistence of vision
help me​

Answer 1

Explanation:

Persistence of vision is the eye's ability to keep seeing an image of an object for a fraction of a second after the object has disappeared from view. The image of an object stays on your retina even after you've stopped looking at it.

Answer 2

Persistence of vision :

• The time for which impression or sensation of an object continues in the eye is called persistence of vision.

• It is about 1/16th of a second which means that the minimum time for which we should give you an object so that its clear image is formed on retina is one/16th of a second.

Additional information :

• A human being has a horizontal field of view of about 150 degree with one eye and of about 180 degree with two eyes.

• So, two eyes give a wider field of view.

• The ability to detect faint objects is enhanced with two eyes.

• Our eyes are separated by a few centimetres and each eye sees is a slightly different image.

• Our brain combines the two images into one tells us how close or far away things are.

• Keeping both the eyes open provide the third dimension of depth.
