摘要： Systems and methods for continuous objective assessment are discussed herein. The systems and methods may comprise sensor(s), a processor, a clock, data storage, and a power source. The sensor(s) may continuously monitor viewing distances, light exposure, or the like, and the system may log corresponding time and/or duration information. Also provided herein are methods of treating, preventing, and/or diagnosing vision impairment risk. These systems and methods may provide warns, such as when detecting the viewing of materials too closely (e.g. ≤30 cm), near to near intermediate viewing (e.g. ≤70 cm) exceeding a predetermined time (e.g. ≥20 min.) without a break, and/or not getting enough outdoor light exposure (e.g. at least 75 minutes of exposure at >1000 lux) for the day.
