How does the Eye Focus?

Actually signals from the eye cortex is sent to the brain to tell your eyes to focus on something. Light goes through the retina to the optic nerves that’s why light hurts our eyes first thing in the morning, your eyes automatically adjust to focus when you are in a dark room it’s pitch black, but after a few seconds the signal is sent to your brain to focus in the dark, then you can start seeing things inside of the dark room.
