How does glaucoma affect your vision?

The optic nerve is made up of many nerve fibers that carry images to the brain. It's like an electric cable containing numerous wires. When glaucoma damages the optic nerve fibers, blind spots develop. If the entire nerve is destroyed, blindness results.

As the optic nerve becomes more damaged, blank spots begin to appear in your field of vision. You typically won't notice these blank spots in your day-to-day activities until the optic nerve is significantly damaged and these spots become large.
