The website requires desktop notifications because that's how it reminds you to take a break. Desktop notifications are supported on Firefox, Chrome and Safari.
- Now a timer will appear, showing you the time till your next break. You may disable sound notifications by clicking the volume icon next to the timer. Once you see a notification, click it and then click Start break. Now your screen will turn dark for the duration of the break. You should look at a point at least 20 feet away. Alternatively, you may click Start Eyes Gymnastics on your screen and the app shows you some eye exercises (move eyes up and down, etc.) that you can quickly go through to reduce eye strain.
