SmartMeiControl vs Lucent

1. Adjust the color temperature, brightness, color, etc. of the lighting fixtures. 2. Regularly turn off the lights. 3. Adjust the lights in each room separately.

Lucent helps you check the light where you read. Using your iPhone camera, it estimates ambient light and gives you a clear reading-light assessment. It also adjusts suggested break intervals as the light changes. CHECK YOUR READING LIGHT Point your iPhone toward your reading area. Lucent shows an estimated light level and tells you whether the conditions are suitable for reading. BREAKS THAT RESPOND TO LIGHT Light conditions shape Lucent’s suggested break interval. Start with a 20-minute baseline, then adjust it from 10 to 30 minutes in Settings. The schedule is Lucent’s own model, inspired by 20-20-20 and adjusted for ambient light. It is not a medical standard or medical advice. KEEP A LOCAL RECORD Review light samples over time and add notes for your desk, bedside, window, classroom, or outdoor reading. Gaps mean no measurement was taken; Lucent does not fill them in. CAMERA, WITHOUT PHOTOS Lucent processes camera data on your device while the app is open. It does not take or save photos or video. Your readings and notes stay on your device. Lucent has no account, ads, analytics, or network connection. WHEN A LIGHT READING IS UNAVAILABLE The timer still works from a fixed baseline if camera access is unavailable or your device cannot provide a light estimate. Lucent never guesses a reading. Lucent estimates light; it is not a calibrated light meter. Its break suggestions are not a substitute for advice from an eye-care professional.
