We cannot perceive the image that falls on the blind spot, because 我們不能看見落在眼球盲點上的影像，這是因為
no image can be formed on the blind spot. 影像不能在盲點上形成
the light-sensitive cells cannot sent signals to the brain. 感光細胞不能把信息傳送到腦
there are no light-sensitive cells on the blind spot. 盲點上沒有感光細胞
it is where the optic nerve leaves the eye. 盲點位於視神經離開眼球的位置
