Question

If there had been one eye of the man, then
(A) Image of the object would have been inverted
(B) Visible region would have decreased
(C) Image would have not seen three dimensional
(D) (b) and (c) both

Answer 1

Hint: From eyes, we can see and observe the things which are in front of us up to a wide visible region because we can move our two eyes simultaneously. But if we close our one eye, then we can observe that our visible region is different from the initially visible region. Use this information to obtain the correct answer form the given options.

Complete step by step answer:
We know that the eyes are an essential part of the human body, and we can see and observe the other thing with the help of eyes. But the condition of eyes gets affected due to various reasons like older age problem, infection, etc. Due to these reasons, the visible region and image of the object get affected. Our eyes consist of different parts so that we can perform the various functions. The various parts of the eyes are retina, macula, optic nerve and vitreous. Due to some reason if we have only one eye then it will affect our visualization capability, our visible range will decrease, and we will face problems in observing the image depth if the object is three dimensional.
Therefore, if there had been one eye of the man, then his visible region would have decreased, and the image would not have seen three dimensional and option (D) is correct.

Note: If a man has two eyes, then these two eyes will cover more range and can observe and see the three-dimensional object in a better way. But the range of the single eye is less as compared to the two eyes. We can observe this thing by observing any object normally as well as by closing our one eyes.
