Sensory Lab Physiology
1.) Why is there a blind spot and why doesn't it interfere with Normal Vision?
Homework Answers
Answer - The cells that make up retina has to connect to the brain via optic nerves. These nerve bundles lie in front of the retinal cells which has to go through the inside surface of eyeball to reach the brain. These nerves after passing through the eyeball inner surface gets collected together and dive back through the retina at a place called the blind spot. Since there is a need for the nerve bindle to dive back through the retina, and since there is no retinal cells present, there is a blind spot present.
It doesn't effect the normal vision because the brain fills in the gaps.

1. Measure the blind spot by closing your right eye, fixating on the X, and move your head closer or further until you can get the circle to disappear. Then do some geometry to find the visual angle of the blind spot. Measure the distance from the X to the center of the circle. Then measure the distance of the X from your left eye when the circle has disappeared. Now compute the visual angle as seen in...
