    We all have blind spots because there’s a hole in the retina in the back of the eye for the optical nerve. The spots are located on the outer top side of our field of view and you can become aware of them with some visual tests online.

      Another fun thing you can do is look at the sky (not the sun!) on a sunny day and start seeing your blood circulation and blind spot.

        The top commenter is correct. It’s why when you glance at a clock with a second hand, it can seem like it takes too long for it to move for the next second. It moved as you moved your eyes, and your brain didn’t make up the movement.
