Why Do We Have Blind Spots?

The video tutorial explores the concept of the blind spot in human vision through an experiment. It explains how the blind spot occurs due to the arrangement of nerves and light-sensing cells in the retina. The brain compensates for this blind spot by filling in the missing information. A small study suggests that practice might reduce the blind spot's size. The video also compares human vision with cephalopods, which do not have a blind spot due to their different eye structure, highlighting evolutionary differences.

What did the researchers find about the sensitivity of light sensing cells around the blind spots?

How do cephalopods avoid the problem of blind spots?
