It seems to be strange to most of you that there is a blind spot（盲点）on your eyes．Here is an interesting experiment that can make something disappear，when on eye is open．
Make a card about the size of the postcard and write two English letters L and R on it，L on the Left and R on the right．First，hold the card about 80 cm away and you see both the letters．Then close your right eye and look at the letter R only with your left eye．And now，as you move the card slowly towards you，you’ll find the letter L disappearing．But if you move the card nearer to your face，the letter will be seen again．Now do the same experiment with your left eye closed，you’ll find the letter R disappearing．
Why does the letter disappear? It is because there is a blind spot on your eye．When the image of the letter falls on your blind spot，it won’t be seen．That is why either of the letter disappears?
