20-20-20 Rule 作者： Shreya

An eye care reminder. Looking at screens too much can lead to eye strain. If you find yourself gazing at screens all day, your eye doctor may have mentioned this rule to you. Every 20 minutes spent using a screen; you should try to look away at something that is 20 feet away from you for a total of 20 seconds. The 20-20-20 rule reminder will help by reminding you to look away every 20 minutes at an object that is about 20 feet away for a full 20 seconds.
