It' seems to be strange to you there is a blind spot(盲点 )on the eyes. Here is an interesting experiment(实验) that can make something disappear, when one eye is open.

Make a card about the size of a 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 the eye. When the image(影像) or the letter falls on the blind spot, it won't be seen. That is why either of the letters disappears.
