In some countries, this may be known as the 10-10-10 rule which is similar, but goes as follows:
 
<big>
* Every 10 minutes
* Look at something 10 meters away
* For at least 10 seconds
</big>
Endmyopia recommends even more breaks.
<big>
* Every 20 minutes, take a 5 minute break.<ref>{{Cite web |title=Eye Strain Awareness: Prevent Pseudo Myopia - Endmyopia |url=https://endmyopia.org/breaks-are-key-to-build-eye-strain-awareness/ |last=Steiner |first=Jake |website=endmyopia.org |access-date=2020-06-01}}</ref>
* As you develop [[Strain Awareness]] you can customize your break schedule to your needs.
