How Your Eyes Work Together

The back of the eye is made up of light-sensitive cells called photoreceptors. There are two types of photoreceptors – rods and cones. However, there is one spot in the eye where there are none of these cells; that is where the optic nerve attaches to the eye. The optic nerve connects the eye to the brain and carries all the images we see to the brain. The optic nerve connecting to the back of the eye causes us to have a blind spot in our vision.


Why don’t we notice the blind spot? There are two reasons. The first is the opposite eye compensates for the missing information and fills it in. This is because when we have both eyes open, the visual fields from each eye overlap and fill in the info for the opposite eye.
