Abstract: 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.
