■ Intuitive and Simple Usage 1. Set Alarm Interval and Volume Click the extension icon in the upper right corner to open the popup window. To use the default setting, simply leave the interval at 20 minutes and the volume as is, then click the blue [Start Alarm] button to schedule the timer. Only if necessary, enter your desired interval (in minutes, up to 60 minutes), adjust the volume using the bottom slider, and click the blue [Start Alarm] button. 2. Instant Status Confirmation Once the alarm starts, a confirmation message like "Alarm scheduled in 20 minutes!" will appear at the bottom of the popup, and the timer will begin running in the background. 3. System Notification & Alarm Sound When the scheduled time is reached, a system popup notification will appear: "Please rest your eyes! Look far away and stretch." Simultaneously, a relaxing alarm sound will play to clearly signal your break time. 4. Background Running Status While the timer is running, a green 'ON' badge will be displayed on the extension icon in the browser toolbar. Hover your mouse over the icon at any time to easily check the current status via a tooltip: 'Eye Health Assistant (Running)'. 5. How to Stop the Alarm To cancel a scheduled alarm or stop the currently playing music, simply click the extension icon in the upper right corner of the browser once. Do not click the [Start Alarm] button in the popup. Clicking the icon will immediately stop the music and completely cancel the alarm reservation. ■ The Perfect Solution for Healthy PC Habits: Eye Health Assistant People who sit at a desk in front of a PC for long periods often fail to realize the toll it takes on their body and eyes. This extension was developed to enforce healthy PC usage habits by prompting users to look away from the monitor and take a break. It can be used not only to relieve eye strain but also as a timer for regular stretching. We strongly recommend it for individuals with diabetic symptoms who require periodic physical movement for blood sugar management. ■ Scientific Basis: The 20-20-20 Rule We applied the "20-20-20 rule," a digital device usage guideline proposed by the American Optometric Association (AOA). Taking regular breaks—looking at an object 20 feet (about 6 meters) away for 20 seconds every 20 minutes—can effectively prevent eye strain and dry eye syndrome.
