Why screen light works for reading
Bedside lamps and overhead lights either flood the room or cast harsh shadows on the page. A screen reading light sits close to your book and produces a wide, even glow at exactly the brightness you choose. The warm temperature avoids the blue-heavy output of standard screens, making it easier on your eyes before sleep.

Start at 50% brightness and 3500K. If the room is very dark, lower brightness to 30-40% so your eyes stay adapted. For e-readers with their own backlight, use the screen light as ambient fill by placing it behind or beside the device. Adjust temperature warmer if you read right before sleep.
Reading light vs night light
The reading preset is brighter and slightly cooler than the night preset because you need enough contrast to read text. The night preset is designed for ambient glow and sleep, while the reading preset balances comfort with legibility. Switch to night mode when you put the book down.
Reducing eye strain during night reading
Eye strain from night reading typically comes from too much contrast between your book or device and the surrounding darkness. The reading preset adds just enough ambient light to reduce this contrast without being so bright that it disturbs a sleeping partner. Position the screen to one side rather than directly behind your book so the light falls across the page evenly without casting shadows from your hands.
