Check the light where you read, then make time for a break. Lucent uses your iPhone rear camera's exposure data to estimate ambient light. See an estimated lux value, a written lighting assessment, and a suggested break interval. It is not a calibrated light meter. CHECK YOUR READING LIGHT Point the rear camera toward your reading area, keep the lens clear, and hold steady. Numbers, written assessments, and a scale help you compare lighting conditions. Fresh ambient readings are taken while Live is visible or when you request a current measurement for a mark. The Timer tab and background timer do not continuously measure light. FOCUS AND BREAKS YOU CONTROL Choose a baseline from 10 to 30 minutes. Suggestions use the latest valid reading and your selected model. Start a focus session, pause or resume, take an early break, or end the whole session. Restart only the current interval without deleting existing records. LOCK SCREEN AND DYNAMIC ISLAND On supported devices, Live Activities show your current phase and remaining time. Availability follows system Live Activity settings. A running countdown does not mean the camera is sampling in the background. OPTIONAL BREAK SOUNDS Enable gentle cues for break start and completion in Settings. Sounds are off by default and follow system silent and notification settings. COMPARE SCREEN AND SURROUNDINGS Try a relative screen-to-environment brightness check, not an absolute screen-brightness measurement in nits. If capture or detection fails, follow the guidance to adjust the angle, distance, or surroundings. LOCAL RECORDS AND CSV Review foreground samples, add a scene label to a current valid reading, and export CSV. Gaps remain gaps; Lucent does not invent readings. Saving a mark requires a fresh reading from that attempt. FOCUS FILTERS A configured system Focus filter can start or pause the timer. It does not enable background camera measurement. Baseline timing remains available without camera access. Reminders require notification permission and follow system Focus and notification settings. Camera frames are processed on your device without taking or saving photos or video. No account, ads, or analytics SDK. Measurements and records stay on your device. Feedback emails and support links open only at your request through system mail or browser services. Light readings and screen comparisons are estimates, not professional measurements. Break suggestions come from Lucent's own model, inspired by 20-20-20, not a medical standard or treatment recommendation.
