To find the blind spot
1. On a piece of paper draw a small circle and a cross about 10 cm apart2. Close your right eye and stare at the circle with your left eye. (The cross can still be seen).
3. Slowly bring the page closer until the cross disappears.
4. Light from the cross is now falling on the blind spot of your left eye.
5. Move the page closer, the cross reappears.
