There are a number of reasons why we close our eyes to sleep. Closed eyelids block light from being absorbed by the eyes, which stimulates the brain to wakefulness. Remember, light is taken in through specialized cells (known as ganglion cells) in the retina.

Not quite. But it's a good second choice. Sometimes referred to as quiet wakefulness, resting with your eyes closed can calm your mind, give at least some of your neurons a break (since you're not actively thinking or concentrating on something), and let your muscles and organs relax.
