Our Story
NightReader started with a simple bedtime frustration: wanting to finish "just one more chapter" before sleep, but waking up groggy because of screen light disruption.
Standard Kindles emit cold, blue-heavy light directly into your eyes right before bed. Beyond delaying your natural melatonin release, bright screens flood the bedroom and disturb your partner.
Pure red light is the only spectrum proven not to suppress melatonin—the essential hormone your body produces for restorative, deep sleep.
We engineered the NightReader cover to fit seamlessly over your Kindle screen, transforming harsh digital illumination into a calm, low-glare reading glow that protects your sleep cycle and keeps bedroom peace.

Reading before bed should help you unwind, not keep you awake. We built NightReader so you can read comfortably in pitch-black rooms without compromising tomorrow morning's energy.
