The 'normal' person will see the two red lines as 'bend'.
Actually both the red lines are straight and parallel, you can confirm this by seeing them from the side of your computer screen instead of directly.
First of all, you have no idea what, "the normal person," or anyone else sees. The subjective experience of, "seeing," cannot be examined or studied by anyone. All you have for, "evidence," is the testimony of others who claim to be able to see.
Perhaps you see two curved red lines, as you claim. I'll take your word for it, just as I have to take your word for it that the world as you directly perceive it, is not the world as it actually is. If that is the case, I'm sorry for you.
To assert that just because you have defective perception and the existents you see aren't actually what you see, but something else (which you can neither identify or know) to attribute your perceptual to others is like your thinking, just because you cannot speak Mandarin, no one can.
In fact, all anyone sees when looking at that image is lines that have been drawn. Whether those line are straight, curved, or form any pattern are all, "interpretations," of what is seen. Only the, "seeing," [which must occur before any interpretation of what is made] is perception. Even for those who interpret those lines as curved, when they see them, had to see them as they exactly are before that interpretation could be made.
