Eye Fresh is a Google Chrome extension developed by eyefreshtool. This free extension aims to remind users to take breaks and give their eyes some rest while using digital devices. Eye Fresh is designed to help users apply therule, which suggests that for every 20 minutes spent on a digital device, users should take a 20-second break and focus their eyes on something 20 feet away. This rule is believed to reduce digital eye strain caused by prolonged screen time.

With Eye Fresh, users will receive notifications that serve as reminders to follow therule. To fully experience Eye Fresh, it is important to ensure that your computer is configured to receive notifications from Google Chrome. Mac users can easily configure their system by going to "System Settings", clicking on "Notifications", finding Google Chrome under "Application Notifications", and enabling notifications according to their preferences.
