Have you ever had the experience that something popped into view? Perhaps it was in your blindspot. You can check your blind spot with a simple exercise.

What is a blindspot?

Our blindspot is caused by the absence of the specialized photosensitive cells, or photoreceptors, in the part of the retina where the optic nerve exits the eye.

Researchers have proposed a number of different explanations as to why we do not notice this blind spot in normal everyday vision. Some suggest that the opposite eye compensates for the missing visual information. One of the most commonly accepted theories is that the brain actually fills in the missing information by using visual cues in the environment.
