The reason for a blind spot in the visual field is that...
- rods are less sensitive to light than are cones
- there are no photoreceptors in the retina where the axon exit the eye
- the lens cannot focus all of the visual field onto the retina
- retinal cells die with age and overuse, resulting in blind spots
- blood vessels collect together and enter the eye at the blind spots
