Overlap in the visual fields of our eyes .
A) leaves a blind spot anterior to the nose and in the lateral fields of vision
B) gives us higher visual acuity for small detail by doubling the number of photoreceptors that are being stimulated
C) is essentially a waste of brain processing for what is essentially the same image
D) allows us to subconsciously estimate the distance of objects based on the different angles the image strikes our two retinas

Question

Quizplus · Accepted Answer

The overlap in the visual fields of our eyes allows us to subconsciously estimate the distance of objects based on the different angles the image strikes our two retinas. This is known as binocular disparity and is a key mechanism for depth perception. Additionally, the brain can combine information from both eyes to enhance stereopsis (the perception of depth and 3D structure). Therefore, it is not a waste of brain processing and does not increase visual acuity. While a blind spot does exist in the visual field, it is not significant enough to affect overall vision.
