3 A paper strip with two crosses on it being cut out by scissors

Make a target shape on the other side of the paper and then cut out the paper strip.

4 Find your blindspot science experiment - using the test card

Hold the paper strip up to your face, so that the cross is in front of your right eye.

The picture of the ‘target’ should be to the right of your face. Close your left eye. Focusing on the cross, slowly move the paper away from your face.

As you move the page away from your face, you notice that at some point you can’t see the ‘target’ within your peripheral vision; you’ve found where your blind is!

Why Does This Happen?

The back of the eye, known as the retina, has a layer of cells that senses light and converts it into electrical impulses. These impulses are then sent to the brain via the optic nerve, enabling us to see.

The blind spot is due to the lack of photoreceptor cells in the area of the retina where the optic nerve exits the eye. This spot is known as the optic disc. Since there are no cells to detect light in this area, it creates a blind spot in our visual field.

You can see the blind spot area in the image below as a light circle area (to the right of the image).
