Why we don't we see two images, as we have two eyes and two retina
We can't call you and give answer.there is no permission for that.
don't worry, I Will answer your doubt in a simple way using simple examples. Please read carefully&read multiple times for better understanding.
Ans:-
Is catching, juggling or heading a ball challenging for you? If you've ever tried threading a needle, did it end in frustration? Have you ever thought of blaming your eyes? Two eyes that work together help you estimate how far a ball is or where the thread is with respect to the needle. This “working together” of the eyes actually happens in the brain.
The brain receives two images (one for each eye), processes them together with the other information received and returns one image, resulting in what we “see”.
Humans have two eyes, but we only see one image. We use our eyes together to gather (get) information about our surroundings. Binocular (or two-eyed) vision has several advantages, one of which is the ability to see the world in three dimensions. We can see depth and distance because our eyes are located at two different points (about 7.5 centimeters apart) on our heads. Each eye looks at an item from a slightly different angle and registers(or makes) a slightly different image on its retina (the back of the eye). The two images are sent to the brain where the information is processed. In a fraction of a second our brain brings one three-dimensional image to our awareness. The three-dimensional aspect of the image allows us to perceive width, length, depth and distance between objects. Scientists refer to this as binocular stereopsis.
hope you understood.If you have any other doubt, put a new question.
