chris crash im worried because i cant find my blind spot.
Try this:
Book/magazine (basically a line of type) hold around 8 inches from your face.
Close left eye, fix right eye on the left most part of that line of type (the first letter).
Slowly move a finger from left to right along that line - you should see the tip of your finger disappear around 4 inches across, carry on and it will reappear on the other side of the blind spot.
Slowly !
Make it obvious, draw a little face on your fingernail :)
