20-20-20 Rule

Prevent eye strain with the 20-20-20 Rule reminder.

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.

Extension safety

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

20-20-20 Rule requires very minimum permissions.
