The large nerve that connects the eye to brain is called optic nerve?

The statement is correct. The optic nerve is a large nerve that connects the eye to the brain, specifically to the optic chiasm and then to the brain's visual cortex. It is responsible for transmitting visual information from the retina to the brain, allowing us to perceive and process visual stimuli. The optic nerve is part of the central nervous system and plays a crucial role in our sense of sight.
