While bright light helps us see better, our eyes need darkness for better vision. Light breaks down the sensitive machinery of our eyes every day, and during the darkness of night, key pieces are rebuilt. The clock of our circadian rhythms runs this process, and researchers have found that if the clock is disrupted, our eyes may be at greater risk of retinal degeneration as we age.
